Reprogramming the Passlock II Security System

Does anyone out there know how to re-program the security sytem for my 1999 Chevy Blazer?

Yeah, it ought to be in the owner’s manual.

There are many internet entries on disabling or bypassing PassLock II. Do a Google search on Passlock II and select the site of current interest to you.

The owner’s manual should read, “Take it to a qualified repair center for reprogramming”. This is where they verify you are the legal owner of the vehicle before they reprogram any security system…
