I have a 2005 GMC Sierra SLT Z71 with an autopage rs-855. No remote when I bought truck. Got remote and programmed. Alarm and remote start work but no door lock/unlock. Am I missing a programming feature? Thanks for any suggestions.

firstly you have to find out if they were connected, if they aren't, then, is your truck the base model or not?

slt model, not base. I can't imagine anyone hooking all this system up and not the door locks, but how can I be sure?

ok, well i don't have any personal experience on your specific vehicle, maybe someone who does can chime in to assist in ensuring the thread is going in the right direction, here's what i can tell you, wiring notes on this site say an interface is required for the door locks, 456g or 457g, so look around under the dash area where the connections are, see if you can locate the power lock harness from the module, check to see if it's connected to a module of some sort, if it is chances are the power locks were connected, but are no longer functional, the troubleshooting part, well the american alarm guys will help you there, just in case you didn't notice where i'm from posted_image .

cheers, and good luck.
