2002 trailblazer doorlocks?

just use a module for the locks. it is a little more money, but well worth it.

I just did a 05 Trailblazer yesterday with a remote start / keyless system. If the vehicle does not have factory keyless (mine did not) then the bypass module that would normally control the doorlocks will not work the doorlocks. If the vehicle had the factory keyless option it would. I found my doorlock wires under the drivers side of the dash in a large white molex directly above the e-brake. This molex was a huge beyatch that plugged into a large black box (bcm?) My wires were a single smal white and a single small light blue that were a positive trigger. The rear tailgate should lock and unlock with the front doors. While your year vehicle is different it is still worth looking into this.Top Secret, I can tell you but then my wife will kill me.

The Viper 455G will do both keyless and nonkeyless entry GM sport utes. Gus Wherever I go, that is where I end up......

I have done a few 2004, 2005.. and regardless if it had keyless to begin with, the GMDL-BP will control door locks, ect.... Hak
