I have an '07 Pilot and the key stopped being able to remotely lock and unlock the vehicle. I swapped out the battery twice but it still didn't work. It did seem to stop working after I accidentally left the driver door cracked for about a week which drained the battery and got some water in the interior. Not sure if that was just a coincidence or if it damaged the lock control unit / master switch and that needs to be replaced.

It's not a huge deal if the remote lock / unlock doesn't work but would be nice. Should I try buying one of these For 2005 2006 2007 2008 Honda Pilot Keyless Entry Car Remote Key Fob CWTWB1U545 | eBay

switching out the inside transponder with my current key and then try programming it like this -


Or try something else? Or do you think the locking control unit is shot and I'm looking at a more expensive repair to fix?

Do all other methods of locking and unlocking still work?

  • key in door
  • manual inside door lock
  • lock button inside driver's door

Do you have a second key? Does that work?

If not, why not take a shot with a replacement from eBay and switch out the transponder guts and reprogram it? They're certainly cheap enough. If fact, if you only have the one key, why not get one their twofer sets?

My backup key is just a valet key. But yeah, I went ahead and ordered one off eBay and will swap it out to see if that works. Thanks for the responses.

I was able to swap and reprogram the new transponder using the steps in my first post. The lock button kept getting stuck on the key shell (Maybe bc it’s not an OEM key) but I drilled the hole bigger and now it’s working great.

OK, glad to hear you got it working.

Now that you've gotten that under your belt, you may wish to consider a flip key as your next step.

Try it twice in a row. :D


Have you gone through the reprogramming sequence?

Get a new fob off Amazon or eBay, with or without the key, whichever is cheaper. Then reprogram all remotes together.

Here's how:

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 1remote 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".


Here's a video that might also help.


Keep trying, it eventually does work, if your fobs are good. In the end, what finally worked for me when using the method that goes from II to 0 didn't work: Going from II to I is what did it for me.
