Silverado key fob not working

[huntingislife]

'00 Chevy Silverado

The key fob will unlock the doors fine but it will not lock them. It will activate the security when I press the lock button but the doors do not lock. Both the lock/unlock work fine on the door switch. I tried reprogramming the fob and it still does the same thing. I would think the batteries in the fob are fine because everything else works. Any ideas on where the problem could be?

Have you taken the fob apart to check battery? Has to fob gotten wet in the past?

I had the same problem on the Saturn except the unlock would not work. Took it apart and found what looked like pop between the button and the contacts on the circuit board. Cleaned it off with electrical cleaner and it has worked great since.

I should add that anytime we have a key FOB problem at the shop we always ask that the customer bring in the spare if available. If everything works with the spare than we can focus on the other FOB.

I will have to take it apart and check it out. Thanks for the suggestions.

I had the same issue with my 04. I pulled the fob apart and cleaned everything and it's worked fine since.

Well, I pulled it apart and it looked real clean. I cleaned it twice but it still didnt solve the problem.

Reason why I asked about taking apart was to make sure and get rubber push pad back in place correct. This pretty easy though and hard to put out of place.

Unless someone else has any further info to give, I would say the fob it self is broke/worn out. For some reason I have seen the lock sides fail on Ford and Chryslers before.

I would have to say it is time for a new fob.

Unless the keyless remote module is not allowing the lock function to operate.

Do you have a spare FOB? Have you tried the spare FOB?

[huntingislife]

I dont have a spare fob. I will probably just order a replacement fob and see what happens.

[Jeremy airjer W]

Sounds like a reasonable next step.

Well, got my new fob and it does the same thing. Where is the remote module for this? Is there anyway to test it?
