Keyless door unlock receiver

I have been told my door unlock receiver module on my 2007 four door Z71 is bad. The symptoms are no communication with the TPMS and the keyless entry won't work. Both fobs are fine so it's not them. Can anyone tell me exactly where it is located please? I think I can replace it myself if I can find it. Thanks!

See if you can find the fuse that says DSM (Drivers seat Module, Remote Keyless Entry System). Should be in the fuse box under IP. If not look in your Owners Manual. Remove the fuse for about 20 minutes. Then re-install and see what happens.

Would removing the battery cables for a couple of hours do the same thing?

That would do the same thing. But it will also reset every module in the truck plus the ECM. I would just pull the fuse. I would just deal with the Keyless Entry for now. Disconnecting the battery usually doesn't cause any problems. BUT there have been times that it does. I have seen it lock up the theft module. And then you would have to deal with that.

Well I did it just like you said but it didnt work. The tech who fixed the air bag issue said his machine was claiming it was the unlock module. Supposed to be on the drivers side somewhere but he was real vague about exactly where.

Welli pulled the two fuses for the keyless remotes, it worked, the reciver is listening to the fobs now!! Thanks,

Good news, glad it worked for someone. Maybe it will help someone else in the in the future.

Skyhigh which fuses did you pull and were you also showing a TPMS error before you pulled the fuses?

BigDaddycat · January 25, 2014

I pulled the DSM fuse but am unaware of another fuse to pull.

I pulled two fuses, there were located in the panel on the side of the dash, large black boxes with 5 pins, try that, mine were pulled for 5 hours at least, good luck

I pulled the lock and unlock breakers,

What I found in the rear drivers side post was an Omron unit that had BCM on it. Small print said Body control monitor, not module, but I bet it is the module. Took drivers side post apart where the seat belt is and didnt see the RCDLR there either. Anyone got any ideas?
