cmp6 ... your post is a little confused.

The VATS and PassLock II are two completely different systems.

On most of the vehicles from at least 1996 to at least 2004 GM used the PassLock II security system . This system is not key specific meaning there is no chip inside the key.

The reason it's a dealer recommended repair is the ignition switch has a specific resistance value and the BCM is configured to recognize it. To properly repair the issue the ignition switch may be replaced and the BCM has to be reconfigured to this replacement switch. This has absolutely nothing to do with the key itself.

The bypass module for a remote start system is simply a box that has a multiple of resistance values available to be selected for a particular vehicle. This module is spliced into the " security " wire from the ignition switch to the BCM after determining what the value is from the ignition switch and selecting that same value in the module.

Sorry, In the VATS system, that there is a resistor present during the start cycle.
However, in the PASSLOCK system, the resistor has been placed inside the ignition switch,
instead of the key.
