I have a 2007 Hummer H3 Tactical Edition. I have been having problema with the car. At times,it just do not want to start.Whether i do it remote start or directly to the ignition with the key.The only thing that makes sense is the GM’s anti -theft feature (GM Pass-Lock System).
Can somebody help me out what to do and if need to install a bypass module,what brand can you recommend. Thanks you !

 

replacement updated ignition switch should fix issue

 

ok.thanks for the suggestion.

 

Anybody tried using a bypass module for the GM Pass lock System?If so,which one is good out there?Thanks !

 

You have an aftermarket remote start, I would look there before anything else.

 

Have you replaced battery terminals. My 07 would act up every once and a while before replacing terminals. Battery was getting old and just wasn’t charging like it should. Both factors caused issues.
