The key fob buttons no longer lock/unlock our 2005 Pilot. Replacing the batteries didn't help, and a Batteries Plus store tested them and said neither fob is transmitting.

It sounds like I can buy the inside chip/transmitter of the fob, swap it with the old one, and reprogram it. What's the best source for ordering these? Does anyone have the part number handy?

Amazon or eBay or AliExpress for the standard fob with remote electronics, but why not use the opportunity to finally put an end to your key jabbing you or making a hole in your pocket, and upgrade to a flip key? I know I wouldn't go back now that I have a couple.

2 +1 3 Buttons Remodel Remote Flip Folding Key Shell Cover For Honda Civic Pilot | eBay

You'll need to carefully dig out and transfer your immobilizer chip and reprogram your fobs.

Have all remotes for the vehicle on hand. Make sure all the doors and rear hatch/trunk are closed during programming. Only need to use 1 remote to get into program mode but all remotes must be programmed during the same session. Each step must be completed within 5 seconds.

1. Sit in the car with all doors/trunk tightly closed

2. Turn the key to the ON position, marked by "II" on the ignition bezel so the dash lights come on, then within 5 seconds press the "Lock" button on the remote for 1 second or so and release the button.

3. Turn the key to the OFF position, marked by "I" on the ignition bezel - dash lights go off.

4. Repeat steps 2 & 3 three more times (A total of 4 times) -- each step must be done within 5 seconds of the previous step.

5. Upon the 4th turning of the key to "ON", press the lock button on one remote, the locks will make a cycling sound (clunk), locks will NOT lock or unlock at this point, they will just make a noise. The system is now in programming mode. Do not turn key off.

6. Within 5 seconds of entering programming mode and within 5 seconds of each other, press the lock button ON EACH remote you are programming, for a second or so and release. This step needs to be completed within 10 seconds. Each time a remote button is pushed, the locks should cycle. Up to 3 remotes can be programmed.

7. Turn ignition completely off and remove the key. Step out of car and close door. The remotes should be programmed and should work. If you have a trunk/hatch release, the button for this feature needs to be held for a few seconds before the trunk/hatch will "pop".

Just out of curiosity ... Why would reprogramming be needed all you are doing is only swapping the shell of the unit. Taking off the battery is the same
thing as replacing the battery you don't need a reprogramming to do that ... are you changing the fobs to a fru replacement ?

OP said he tried replacing battery to no avail, so he'll probably need new fob remote electronics, hence the need to reprogram.


  1. Get a replacement fob on Amazon, eBay or AliExpress, You may or may not want to get it with the shell, but you can keep using your original shell and key if that's all you want. All fobs will need to be reprogrammed together. https://www.amazon.com/Honda-2006-2008-PILOT-3-Button-Remote/dp/B000KYX9GI
  2. Optional upgrade: Get a flip key and transfer the new fob to it, which needs to be reprogrammed, then transfer the little immobilizer chip, which does not need to be reprogrammed.
  3. Get the flip key cut at locksmith who does car keys. Call ahead to be sure.
  4. Enjoy living the flip key lifestyle.:smile: From here on in, no more holes in your pocket or key jabs to your inner thigh.:surprise:
