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.

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, 

 or 

 is required.

The Passkey III system can be found in the following vehicles:

‘97 and newer Park Avenue

•

‘98 and newer Cadillac
