So I hop in the G and the lock buttons were not responding when I try to lock or unlock. It was like this throughout the trip. I did lock the car with the remote key but the buttons still wouldn't respond. After I reached my destination and turned off the car, the lock buttons were working perfectly fine. Has this happened to anyone else.

 

Dumb question, I know, but were all of the doors completely shut? I've seen that cause the locks to not function and the only alert you get is the little "!" light.

 

Sounds like an issue with your BCM -- during the period when the locks were not working, did you hear the relay "clicks" with the lock and unlock buttons depressed? If not, then it's your BCM likely -- in the passenger kickpanel ..

If you dont' recall the clicks .. perhaps it's a problem closer to the lock motors .. however, there are four lock motors (obv. one at each door), and only one lock relay (i learned this after extensive time at the BCM installing KP's autolock module)... would probably be quick to blame that relay before blaming anything else.

I would ask you to check fuses... but it started working again and that would be unheard of it a fuse blew.

 

This has happened to me a couple of times...Turn the car off, turn it back on...works fine...

 

It works fine now. That was weird.

 

This happened to me this past Friday night. Had to unlock the door manually. The car locked OK with the Key FOB. When I got back into the car to head home it worked fine.

 

this has happened to me twice... the first time it happened i was really worried cuz i thought i wouldn't be able to lock my car. But then the second time it happened, i just turned the car off, and then on again. It was really strange!!

 

Question: Do you know where the Lock relay is located?

 

this happens to me as well.

how many of you have installed/had someone install factory illuminated kick plates?
