Changing your Honda key fob battery should be a straightforward task, but sometimes it can lead to frustration when you find your Honda Key Fob Not Working After Battery Change. Don’t worry, you’re not alone, and often the solution is simpler than you might think. As your trusted auto repair experts at keyfobx.com, we’re here to guide you through the process of resynchronizing your Honda key fob, getting you back on the road quickly and without the need for expensive dealership visits right away.
Step-by-Step Guide to Reprogram Your Honda Key Fob
The issue you’re experiencing is likely due to the key fob losing its synchronization with your Honda’s security system after the battery replacement. Thankfully, Honda has designed a relatively simple procedure to re-establish this connection. Follow these steps carefully to reprogram your Honda key fob:
Step 1: Get Inside Your Honda and Prepare
First, ensure you are inside your Honda. It’s crucial for all doors, including the boot lid or hatchback, to be completely closed and properly latched. This ensures that the system can accurately register the reprogramming signals.
Step 2: Turn the Ignition to the “ON” Position
Insert your Honda key into the ignition. Turn the key to the “ON” position. This is usually marked as “II” on your ignition bezel. At this point, your dashboard lights should illuminate. It’s important to perform the next step within 5 seconds of reaching the “ON” position.
Step 3: Press the “Lock” Button
Within those crucial 5 seconds of turning the key to “ON”, locate the “Lock” button on your Honda key fob. Press and hold the “Lock” button for approximately one second, then release it.
Step 4: Turn the Ignition to the “OFF” Position
Next, turn the ignition key back to the “OFF” position. This position is typically marked as “I” on the ignition bezel. When done correctly, your dashboard lights should turn off.
Step 5: Repeat the “ON” and “OFF” Cycle
Now, you need to repeat steps 2, 3, and 4 a total of four times. This means you will cycle the ignition from “OFF” to “ON” and press the “Lock” button each time for a total of four repetitions. Remember, each step must be completed within 5 seconds of the previous one to ensure the system enters programming mode correctly.
Step 6: Enter Programming Mode and Activate Remotes
On the fourth turn of the key to the “ON” position, press the “lock” button on one of your remotes. If you’ve followed the steps correctly, you should hear the car locks cycle, making a distinct “clunk” sound. It’s important to note that the doors may not actually lock or unlock at this stage; the “clunk” sound simply indicates that the system has entered programming mode. Do not turn the key off at this point.
Step 7: Program Each Remote
Within 5 seconds of entering programming mode, and then within 5 seconds of each other, take each Honda key fob you want to program (including the one you just used to enter programming mode). Press and hold the “lock” button on each remote for about a second, then release. Each time you press a remote button, you should hear the locks cycle again. You can program up to three remotes using this procedure. This entire step needs to be completed within 10 seconds.
Step 8: Finalize Programming
Finally, turn the ignition key completely to the “OFF” position and remove the key from the ignition. Step out of your Honda, close the door, and test each of your programmed key fobs. The remotes should now be programmed and functioning correctly, allowing you to lock and unlock your car remotely.

Testing Your Honda Key Fob
Once you’ve completed these steps, test all the buttons on your key fob. The lock and unlock buttons should now work as expected. If your key fob has a boot lid or hatch release button, remember that this button typically needs to be held down for a few seconds before the boot lid or hatch will open.

If you’ve meticulously followed these steps and your Honda key fob is still not working after the battery change, there might be another underlying issue. In such cases, it’s advisable to consult with a professional.
