One of my installers was having trouble getting his unlock to work on his 02 Trailblazer. He has a Viper 791xv and is using the 457g. The vehicle starts, runs, and locks just fine. But when he attempts to unlock, all door except the drivers door will unlock. The drivers door will unlock and then lock back quickly. He tried another 457, got the same results, and then tried another 791 brain, and still got the same results. Anyone have an idea of why this is happening and how to fix it? I've done quite a few of these 457's and never ran into any problems like this, so Im not sure what to tell him to look for. Thanks.

ok I read that thread before posting this one, it may be that the same part is the cause of the problem, but since these seem to be two different problems, I felt it necessary to post and find results specific to this problem. thanks for your input but it doesnt help me any. The thread you posted deals with both front doors, mine is only with the drivers door not staying unlocked.

Sorry,

With factory key fob is it do the same problems ??

1-If not I suggest you to install a GM-SL VR-4.9 interface bypass. This unit use the same factory code from you factory keyless. It should be work.
