Key fob does not unlock/lock/or panic. Interior lights do not turn on when I open door but turn on if the truck is on. Same with door locks, if the truck is running or in accessory the locks will work but with truck completely off I have no door locks or fob. Any idea what could cause this.

 

What year? and do you have an after market keyless entry / alarm system or the factory key fob.

There are a few members on here that are very knowledgeable with the keyless systems.
I'm just going to take a guess that it might be the RKE (remote keyless entry) module or possibly the ignition switch. Let someone else chime in that knows the key fob system a bit better before you act on my suggestion first - I'm just going off of memory from prior threads I've read before.

Oh also, how long as this been happening, and have you recently changed anything with the truck that may have interfered with truck?

 

I found out that the IOD fuse was bad

 

After replacing the fuse, is your check engine light on? I just replaced mine today, and my check engine light is on. Truck is running fine, and everything is working, but stupid CEL is still on.

 

Itsa,

Have the light reset by an auto store or somewhere similar and if it returns post up the code.

 

The light went out Monday morning when I fired it up to go to work. Thanks for the reply.
