1995 and newer vehicle anti-theft systems
(immobilizers)
1995 and newer vehicle anti-theft systems (immobilizers) require a bypass module. The bypass module allows for
easy interfacing, while still maintaining the OEM system’s integrity.
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
■ ‘99 and newer Alero
■ 2000 and newer Impala and Saturn
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 555L or p/n 555T is required.
