I have a 990 Python system in a 2005 Denali. The system was installed at Circuit City last March. The doors stop locking when arming the alarm with the remote. But everything else works. Does anyone have a solution? Thanks

Under the dash there should be a little black box, that might say GMDLBP on it, there should be a green wire coming out of it, this is your lock wire input, follow this wire to the remote start wire, check the conection points where the 2 wires meet along the way, if you can't or don't want to do this, go back if you can to where it was put in, they should fix the problem for free

Hey thanks will try tomorrow to find that wire. But Circuit City is closing its door so i dont think they will look at it. But i will give them a call.

Well done Mr. Bond! It could also be a bad bypass module for your door locks.
