When your iPhone's home button stops responding, it’s a uniquely frustrating feeling. That single button is your command centre for navigating your device, and when it fails, your entire phone can feel unusable. It’s a common problem, especially for older models, but the fix is often simpler than you think.
Before you start worrying about a costly replacement, let’s explore what’s likely causing the issue. The culprit behind a non-responsive home button typically falls into one of two categories: a software glitch or a hardware failure. This guide will walk you through troubleshooting the problem and explain your best options for a fix, whether you're a DIY enthusiast or looking for professional iPhone repairs in Brisbane.

Getting to the Bottom of a Faulty Home Button
Most of the time, the problem isn't physical at all. It's often just a software glitch causing the issue. An app might have crashed in the background, a recent iOS update could have introduced a minor bug, or the button's calibration may have gone slightly out of alignment. These are the best-case scenarios because you can usually fix them yourself without any special tools.
On the flip side, you could be looking at a hardware fault. This means there’s a physical problem with the button mechanism or the parts it connects to. This can happen for a few reasons:
- Wear and Tear: After thousands upon thousands of clicks, the mechanical parts can simply wear out.
- Physical Damage: A drop, even a small one, can be enough to knock the delicate flex cable loose that connects the button to the main board.
- Liquid Damage: Moisture is the enemy of electronics. If any liquid gets inside, it can cause corrosion and short out the connections.
Your First Port of Call: AssistiveTouch
Before you start any serious troubleshooting, you need a way to use your phone. Apple has a brilliant built-in feature for this called AssistiveTouch. It puts a virtual home button right on your screen, giving you back full control while you figure out the real problem.
To activate it, navigate to Settings > Accessibility > Touch > AssistiveTouch and flick the switch on. A small grey button will pop up on your screen. Tap it, and you'll get a menu with access to the Home screen, Siri, Control Centre, and more. It’s the perfect temporary fix.
Is It Software or Hardware?
So, how do you know what you're dealing with? It's a process of elimination. You start with the simple software fixes first. If you try all of them and the button still isn't working, you can be pretty sure it's a hardware issue.
This initial diagnostic step is crucial. It stops you from wasting time and money chasing a physical repair when a simple reboot or restore could have solved it. Whether you're a DIY enthusiast or looking for professional iPhone repairs in Brisbane, taking a moment to diagnose the problem puts you in the driver's seat. It helps you make a smart, informed decision on what to do next.
Software Fixes to Try Before You Grab Your Tools
Before you even think about opening up your iPhone, it’s worth running through all the possible software fixes. You’d be surprised how often a “broken” home button is just the victim of a software glitch, and sorting it out costs nothing but a bit of time.
An unresponsive home button isn't always a sign that the part itself is dead. Sometimes, the iPhone's operating system just gets confused, causing it to ignore the button presses. By systematically checking these software solutions first, you can confidently rule out any system-level problems.
Using AssistiveTouch to Get By
As mentioned earlier, AssistiveTouch is your best friend right now. It's the immediate workaround that makes your iPhone perfectly usable while you figure things out. Think of it as your digital lifeline.
To really make it work for you, jump into the settings and tailor it to your needs.
-
Go to:
Settings > Accessibility > Touch > AssistiveTouch. -
Then tap:
Customise Top Level Menu. - What to do: Here, you can add, remove, and rearrange the icons. For instance, you could swap out a function you never use for a one-tap shortcut to the "App Switcher" or "Siri". It’s a small tweak that can make a huge difference to your daily workflow.
The Ultimate Software Test: A DFU Restore
If a simple restart didn't do the trick, the next—and most definitive—step is a Device Firmware Update (DFU) restore. This isn't your standard restore through iTunes or Finder; it's a much deeper process that reloads every single bit of your iPhone's software and firmware from scratch.
A DFU restore is the final word on whether your
iphone home button not workingis a software or hardware problem. If the button is still dead after a successful DFU restore, you can be 99% certain the issue is physical and needs a hardware repair.
The big difference is that a DFU restore lets your iPhone talk to your computer without loading the operating system first. This bypasses any dodgy software that might be causing the problem and gives you a completely fresh start. Just remember, make sure you have a recent backup, as this process will wipe everything clean off the device.
To get this done, you'll need a computer with either iTunes (on older Macs and PCs) or Finder (on newer Macs). The button combination to enter DFU mode changes depending on your model:
-
iPhone 8 and newer:
- Quickly press and release Volume Up.
- Quickly press and release Volume Down.
- Press and hold the Side button until the screen goes black.
- Keep holding the Side button, then press and hold the Volume Down button for 5 seconds.
- Let go of the Side button but keep holding Volume Down for another 10 seconds. The screen should stay black.
-
iPhone 7 and 7 Plus:
- Press and hold both the Side button and the Volume Down button together for about 8-10 seconds.
- Release the Side button but keep holding Volume Down for another 10 seconds. Again, the screen must stay black.
Your computer should then pop up a message saying it has detected an iPhone in recovery mode. Just follow the on-screen prompts to restore it. Once the restore is finished and you've set up your iPhone, give the home button a test. If it’s working, you've just saved yourself a repair. If the iphone home button not working problem is still there, you now know for sure: it’s time to look at the hardware. For more specific software tips, community forums like those on AppleVis can be a great place to find user discussions and solutions.
Taking Matters into Your Own Hands: A DIY Home Button Replacement Guide
So, you've tried all the software tricks and your home button is still on the fritz. When things like a DFU restore don't work, it’s a pretty clear sign the issue isn't with the code—it's physical. For anyone with a bit of confidence and a steady hand, swapping out the home button yourself is the next logical step.
This is a really satisfying repair that can save you a bundle and bring your device back to full working order. It's especially worthwhile for popular models like the iPhone 7, iPhone 8, and the various SE generations where the home button is still a key feature.

Before diving into a hardware fix, it's always smart to exhaust the software options. After trying simple workarounds like AssistiveTouch, a full DFU Restore is the final software step before you can confidently say it's time to open up the phone.
Gathering Your Essential Tools
You wouldn’t perform surgery with a butter knife, and the same goes for phone repair. Having the right tools isn't just a suggestion; it’s the difference between a successful fix and a costly mistake.
For a home button replacement, you'll absolutely need this gear:
- Pentalobe P2 Screwdriver: This is for those two pesky proprietary screws at the bottom of every iPhone. No other screwdriver will do.
- Spudger: An essential, non-conductive pry tool. You'll use this to safely pop open connectors without frying the logic board.
- iOpener or Heat Gun: The screen is held on with some serious adhesive. A bit of gentle heat makes it pliable, so you can open the phone without cracking the glass.
- Suction Cup and Opening Picks: These work together. The suction cup creates a small gap, and the picks slide in to slice through the adhesive seal.
- Tweezers: You'll be dealing with tiny screws and cables. Good tweezers are non-negotiable for handling them with precision.
The Repair Process, Step by Step
Alright, tools at the ready? The most important advice is to work slowly and be methodical. Rushing is your enemy here.
First things first, power the phone off completely. Next, grab that pentalobe screwdriver and remove the two screws flanking the charging port. Now for the heat—gently warm the edges of the display with your iOpener to soften that watertight seal.
With the adhesive softened, place a suction cup near the bottom edge and pull up gently to create a tiny opening. Slide an opening pick into that gap and carefully work your way around the edges, cutting through the adhesive. Be very careful not to push the pick in too far.
Crucial Tip: Remember that on the iPhone 7 and newer, the screen opens to the right, like a book. Don't try to lift it straight up! Forcing it the wrong way will instantly tear the delicate display cables. Always double-check the opening method for your specific model.
Once the screen is free, don't yank it off. It’s still connected by several fragile ribbon cables. The next step is the most critical: disconnect the battery. This prevents any accidental short circuits. You’ll need to remove a small metal bracket over the connector, then use your spudger to gently pop it off the logic board.
With the phone de-energised, you can safely move on to the display and home button cables. The home button’s ribbon cable is notoriously thin and easy to damage, so be extra gentle. Remove its protective bracket, then carefully unclip the connector.
The Touch ID Reality Check
This is the part where we have to deliver some tough news. When you replace your home button, you will permanently lose Touch ID functionality.
Why? Apple pairs the original home button to the logic board with a cryptographic key at the factory. It’s a security feature. This means no third-party replacement—not even a genuine one from another iPhone—can restore the fingerprint sensor.
The goal of this repair is to get the essential click and "return to home" functions back, making your phone perfectly usable again. A high-quality replacement part will restore that physical functionality perfectly, but the Touch ID is gone for good. It's a trade-off you have to accept before starting.
Fixing your own gear is a powerful feeling, and it ties directly into the importance of the Right to Repair movement and the fight against e-waste.
This repair also throws the cost of different options into sharp relief. Going directly to Apple for an out-of-warranty "other damage" repair like a home button can set you back around A$319 in Australia. That price tag makes DIY and independent repair shops much more attractive. Of course, the success of your repair depends heavily on the quality of the parts you use. It's worth taking a moment to check out our guide on how to avoid buying low-quality iPhone parts to ensure your hard work lasts.
DIY vs Professional Repair Cost and Time Comparison
Deciding whether to tackle this yourself or hand it over to a pro involves weighing up cost, time, and risk. Here’s a quick breakdown of what you can expect in Australia.
| Factor | DIY Repair (Using a Kit) | Professional Third-Party Repair | Official Apple Service |
|---|---|---|---|
| Estimated Cost | A$30 - A$60 (includes tools & part) | A$80 - A$150 | A$319+ (out-of-warranty "other damage" fee) |
| Time Commitment | 1-2 hours (for a first-timer) | 30-60 minutes (same-day service) | 3-7 business days (mail-in service) |
| Risk | Moderate. Risk of damage if not careful. You are liable for any mistakes. | Low. Experienced technician handles the repair. Usually offer a warranty. | Very Low. Apple-certified technicians, but the highest cost by far. |
| Key Benefit | Lowest cost, rewarding experience. | Fast, convenient, and reliable. | Uses genuine parts, but you pay a significant premium. |
Ultimately, a DIY repair offers incredible value if you have the patience. However, if you're short on time or nervous about causing more damage, a professional third-party repair from a service like Screen Fixed Brisbane is an excellent, cost-effective alternative.
The Reality of Losing Touch ID After Repair
Caption: Replacing an iPhone home button restores click functionality but permanently disables the Touch ID feature due to Apple's security pairing.
Before you pick up a screwdriver for a home button repair, there’s a crucial reality you need to accept: you will permanently lose Touch ID. This isn't a glitch or a sign of a dodgy part. It’s a deliberate security feature built into every iPhone by Apple, and it affects every single repair done outside of their authorised network.
Why Touch ID Can Never Be Restored
The secret is buried deep inside your iPhone, in a tiny but mighty chip called the Secure Enclave. You can think of it as a high-security digital vault that guards your most sensitive information, especially your fingerprint data.
When your iPhone is first assembled, Apple forges a unique cryptographic link between your specific home button and the phone’s logic board. It’s like a digital lock and key that are made for each other and can't be replicated. Every time you used Touch ID, the Secure Enclave checked this unique signature to verify it was really you.
When you install a new home button—even if it’s a genuine Apple part taken from another identical iPhone—that cryptographic key simply doesn't match. The Secure Enclave instantly flags it as an unauthorised component and, to protect your data, permanently shuts down the Touch ID function. This is hard-coded into the hardware and there’s no way around it.
What a Replacement Button Can Do
Losing Touch ID is definitely a trade-off, but a high-quality replacement button is far from a downgrade. It’s the key to breathing new life into a device that’s become a source of daily frustration.
A new button will restore all the crucial physical functions you depend on:
- The Click Function: That familiar, tactile click will be back, letting you return to the Home Screen with a simple press.
- Double-Click for App Switcher: You’ll get back the ability to quickly pull up and switch between all your open applications.
- Holding for Siri: If you use it, pressing and holding the button will activate Siri just like it always did.
In short, the button will feel and act exactly as it should, just without the fingerprint scanning. You'll go back to using your passcode to unlock your phone and approve purchases—a small price to pay for a fully functioning device.
Focusing on a Practical Solution
When your iphone home button not working is a hardware problem, the game plan has to shift from a perfect restoration to a practical one. This simple fix makes your iPhone navigable again and can add years to its life, saving you from a much more expensive upgrade. Understanding these repair limitations is also part of keeping your phone's data safe. You can learn more in our detailed guide on phone repair data security and privacy. For both professional techs in Brisbane and DIYers across Australia, setting this expectation is the first step to a successful repair.
Knowing When to Call a Professional Repair Service
There's a massive sense of satisfaction that comes from fixing your own phone, but DIY repair isn’t always the best move. Sometimes what looks like a simple home button fault is really just the tip of the iceberg, hinting at a much deeper problem.
Signs You Need an Expert
If any of these situations pop up during your repair, it’s a clear sign to stop and find a professional technician. These are classic red flags that point to problems far more complex than just a dodgy button.
- The Problem Continues with a New Button: You've carefully installed a brand new home button, and… nothing. The "iphone home button not working" problem is still there. This almost always means the fault isn't with the button but with the logic board it connects to, and that requires specialist micro-soldering skills.
- Your iPhone Won't Power On: You've put everything back together, but now the phone is completely dead. This could be anything from a short circuit to a damaged connector or a battery that wasn't disconnected properly.
- Accidental Damage Occurs: A flex cable tears, the screen cracks under pressure, or a microscopic screw vanishes. A pro technician has seen it all before and has the parts and experience to fix these secondary issues without breaking a sweat.
The Value of Professional Service
Deciding to hand your phone over to a professional isn't giving up; it's making a smart call. Technicians have the right tools, years of hands-on experience, and the muscle memory that comes from doing these exact repairs day in and day out.
A good repair service uses high-quality parts and, most importantly, provides a warranty on their work. That warranty is your peace of mind. For more tips on what to look for, check out our guide on how to find affordable phone screen repair services near you.

Got Questions About Home Button Repairs? We’ve Got Answers.
Even with a full guide, it's natural to have a few questions rattling around. Let's tackle some of the most common questions we hear.
Will a New Home Button Fix My Touch ID?
The short answer is a hard no. Once you swap out the original home button for any third-party replacement, Touch ID is gone for good. This isn't because the new part is faulty; it's a security feature built right into the iPhone by Apple. Your phone's original button is cryptographically tied to the logic board. A new button will bring back the physical click, but it can't replicate that unique security handshake.
Can I Just Use a Home Button From Another iPhone?
It’s a logical thought, but unfortunately, the answer is still no. Even a home button pulled from the exact same iPhone model will act just like a brand-new third-party part. That critical security pairing is unique to your specific phone and its original button. The moment you swap it, that link is broken, and Touch ID is disabled.
How Can I Tell if It’s a Software or Hardware Problem?
The most reliable way to figure this out is to perform a full Device Firmware Update (DFU) restore. This isn't just a simple reset; it wipes and reinstalls every single line of your iPhone's software and firmware from the ground up. If you go through a full DFU restore and the home button is still dead, you can be 99% certain you're looking at a hardware fault.
Is It Really Worth Fixing an Old iPhone Home Button?
For many older models like the iPhone 7, 8, or the SE series, absolutely! It's one of the most cost-effective repairs you can do. A DIY home button replacement kit often costs less than A$50, bringing back full navigation and breathing new life into your device for a tiny fraction of what a new phone would cost. When you weigh that against the annoyance of using AssistiveTouch forever or forking out hundreds for a new device, a simple part swap is fantastic value.
If you've pinpointed a hardware issue but decided the DIY path isn't for you, Screen Fixed is ready to help. Our expert technicians can sort out the repair quickly and professionally, getting your iPhone back into your hands and working like it should.
