  Searched and found a couple threads on this topic, but they were several years old and were closed... On my wife's 06 Trailblazer I installed a keless entry and used a DEI 457G interface. Everything works fine,all doors and hatch unlock, but when you lock the doors, the hatch won't lock.  Do I need a diffeent interface? or is this one faulty?   I assume it doesn't need programming, since it seems to be communicating with the vehicle? Thanks...

That was a problem with some 457G's.    Try changing that to a GMDLBP,  it's cheap and works well.  And fixes that problem.

 I got the new interface installed, but now I have to press the unlock button on the transmitter 3 times to get the doors to unlock. It's like it needs a triple pulse to unlock the doors....Any suggestions?

   Thanks....

 I figured out the problem.... I had to go into the GMDLBP's programming and set the  to Driver's Door Priority to OFF.... It now unlocks with one touch of the UNLOCK button on the transmittter.   .trailblazer hatch won't lock w/ rke syst - Last Post -- posted image.
