1995 and newer, VATS (immobilizers)
1995 and newer vehicle anti-theft systems (immobilizers) require a bypass mod-
ule. The bypass module allows for easy interfacing, while still maintaining the
OEM system’s integrity.
passlock I and passlock II (PL-1 and PL-2)
The Passlock I and Passlock II systems can be found in the following General
Motors vehicles:
‘95 and newer Cavalier and Sunfire•
‘96 and newer Achieva, Grand Am, and Skylark•
‘97 and newer Intrigue, Malibu, and Cutlass•
‘98 and newer trucks, vans, SUVs•

Passlock I and II systems are VATS-evolved. Passlock systems still rely on the R-
code to start, but the pellet is no longer placed in the key. The resistor can now
be found in the key switch. This allows for a greater number of possible R-codes.
In addition, Passlock systems require “seeing” the correct R-code at the correct
time. To bypass Passlock I and II, p/n 556L(W) or p/n XK06 is required.
passkey III (PK-3), transponder-based systems
