Introduction

Use this guide to replace the home button assembly.

Please note that only the phone's original home button assembly will be capable of using the Touch ID functionality. Installing a new home button will only restore ordinary home button functions, not the Touch ID features.

You can also use this guide to replace the following parts:

Video Overview

  1. Before disassembling your iPhone, discharge the battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
    • Before disassembling your iPhone, discharge the battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

    • Power off your iPhone before beginning disassembly.

    • Remove the two 3.6 mm P2 Pentalobe screws next to the Lightning connector.

    • The next two steps demonstrate using the iSclack, a great tool for safely opening the iPhone 6 Plus that we recommend for anyone doing more than one repair. If you aren't using the iSclack, skip down two steps.

    • If the plastic depth gauge is attached at the center of the iSclack, remove it now—it's not needed for larger phones like the iPhone 6 Plus.

    • Close the handle on the iSclack, opening the suction cup jaws.

    • Place the bottom of your iPhone in between the suction cups.

    • Position the iSclack's upper suction cup against the display, near the home button.

    • Open the handles to close the jaws of the iSclack. Center the suction cups and press them firmly onto the top and bottom of the iPhone.

  2. Hold onto your iPhone securely and close the handle of the iSclack to separate the suction cups, pulling the front panel up from the rear case. The iSclack is designed to safely open your iPhone enough to separate the pieces, but not enough to damage any of the display cables.

    • Peel the two suction cups off your iPhone.

    • Skip the next three steps and continue on to Step 7.

  3. If you don't have an iSclack, use a single suction cup to lift the front panel:
    • If you don't have an iSclack, use a single suction cup to lift the front panel:

    • Press a suction cup onto the screen, just above the home button.

    • Be sure the cup is pressed securely onto the screen to get a tight seal.

  4. While holding the iPhone down with one hand, pull up on the suction cup to slightly separate the front panel assembly from the rear case.
    • While holding the iPhone down with one hand, pull up on the suction cup to slightly separate the front panel assembly from the rear case.

    • Take your time and apply firm, constant force. The display assembly is a much tighter fit than most devices.

    • Using a plastic opening tool, begin to gently pry the rear case down, away from the display assembly, while continuing to pull up with the suction cup.

    • There are several clips attaching the front panel assembly to the rear case, so you may need to use a combination of the suction cup and plastic opening tool to free the front panel assembly.

  5. Pull the plastic nub to release the vacuum seal on the suction cup. Remove the suction cup from the display assembly.
    • Pull the plastic nub to release the vacuum seal on the suction cup.

    • Remove the suction cup from the display assembly.

  6. Pull the home button end of the front panel assembly away from the rear case, using the top of the phone as a hinge. Open the display to about a 90º angle, and lean it against something to keep it propped up while you're working on the phone. Add a rubber band to keep the display securely in place while you work. This prevents undue strain on the display cables.

    • In a pinch, you can use an unopened canned beverage to hold the display.

  7. Several clips along the top edge of the front panel form a partial hinge, allowing the front panel assembly to swing open like a book. During reassembly, align the clips just below the top edge of the rear case. Then, slide the front panel upward until its top edge is flush with that of the rear case.

    • Use a clean fingernail or the edge of an opening tool to gently pry the battery connector up from its socket on the logic board.

    • Take care to only pry up on the battery connector, and not the socket on the logic board. If you pry up on the logic board socket, you may break the connector entirely.

  12. Remove the following Phillips screws securing the front panel assembly cable bracket:
    • Remove the following Phillips screws securing the front panel assembly cable bracket:

    • Three 1.2 mm screws

    • One 1.5 mm screw

    • One 2.9 mm screw

    • Do not attempt to insert longer screws into the red marked screw holes. Doing so may result in irreparable damage to the logic board.

    • Use a plastic opening tool to disconnect the display data cable connector.

    • When reassembling your phone, the display data cable may pop off the connector. This can result in white lines or a blank screen when powering your phone back on. If that happens, simply reconnect the cable and power cycle your phone. The best way to power cycle your phone is to disconnect and reconnect the battery connector.

  17. Finally, disconnect the digitizer cable connector. When reconnecting the digitizer cable, do not press the center of the connector. Press one end of the connector, then press the opposite end. Pressing in the center of the connector can bend the component and cause digitizer damage.

Hi guys, I replaced my front assembly and I'm having the opposite issue with my home button: The TouchID is working fine, but the home button being pressed is not working. I've tried re-seating the cable a few times. I'm normally pretty good at these kinds of things but I'm assuming I may have somehow crimped one of the ribbon cables.

My question: If something is damaged, is it more likely the cable on the back of the heat-sink that is damaged, or the home button ribbon cable itself? I realize that I will lose TouchID if its the latter, I just want to know what my options are. I'm having trouble searching the issue because everyone else has the issue where the TouchID doesn't work (for obvious reasons) but mine is working just fine.

Thanks for any advice.

Hi everyone, I replaced the home button on my cell phone iphone 6+, the home button functionality works just fine, however the biometrics fingerprint reader does not work anymore. Any suggestions? Thank you

Unfortunately, as stated in the introduction to this guide, that outcome is normal. For security reasons, the fingerprint sensor is coded to your phone's logic board at the factory. If you replace the button, you'll lose the fingerprint sensor function. Only Apple has the capability to pair new Touch ID sensors to existing phones. As far as I know, there are only two ways around this: (1) replace both your home button and logic board with a factory-paired home button and logic board harvested from another phone, or (2) pay Apple for an out-of-warranty repair (meaning you ship your phone to them and they give you a refurb in return).
