The power unlock button in car is working fine but the vehicle has stopped responding to Key FOB. I have checked Fuse 20 under steering column. Can someone give me or point to the diagnostics steps for this?

 

I'm working on the same problem. Check out my thread to see what I'm doing. I had to take a break from it for a week, as my truck is currently getting a valve job done. I'll be back to figuring it out next week.

Is the light illuminating when you push the button?

Maybe try changing the battery to see if its too weak?

Once you confirm the remote is working, you will probably have to check the receiver to see if it has a loose connection.

Located just in front of the rear sunroof under the headliner.

In the end, you will probably need someone with a computer to reprogram/reestablish the link.

That's all I got. Have you checked RAVE for a procedure?
