Using GMDAA the truck locks but doesn't unlock. I saw an earlier posted thread which was left unanswered; but it was locked. Anyhow, WTF sometimes these modules piss me off.

We tried a module from a different company I forget which one. But that one does the opposite; unlocks but doesn't lock. Does trailblazer have a specific one just for it? This isn't the first time i've heard of this either.

Use the crimestopper GM-u7. Does it all.. automatically adjusts to the platform your truck uses..Does heated seat,mirrors and factory alarm.. Also does the RAP module.....

I use the OMEGA (who has the patent on most of these DataBus Units) DB-GMDL-BP for ByPass & Door Locks......OR.......DB-DLM-3 for Doors Locks Only

Did you have the Doors closed and Key OFF when you tried yours??
