can anyone tell me the computer module location so i can set my keyless entry pad. i do not have the master code that has the 5 digit number & the factory preset is on the computer module

 

behind the rear seat on the drivers side

 

You might not find a computer back there. But, you should find the master code.

 

Could you be a little more specific please... I have an '05 Crewcab... would it be under the seat, on the back wall, etc...

Thanks.

 

Behind the rear seat on the back wall of the cab on the driver's side.

 

Thanks, how do I access that wall (I can't seem to get the seat to move forward). Do I have to dis-assemble the seat?

Thanks for your patience - I've only had the truck a couple days...

 

The rear seat back has to be removed. I know there have been several good posts detailing the how-to, if you run a few searches you should pull up some excellent instructions to help you get the rear seat back out without tearing anything up.
