GM VATS (Vehicle Anti-Theft System) Bypass module
(For PASSkey I and II type VATS)
The VATS bypass module is intended for use when installing a GM engine equipped with PASSkeyII type VATS (Vehicle Anti-Theft System) into a vehicle missing the BCM (Body Control Module), permanently bypassing a failing VATS, or for momentarily bypassing the VATS for a remote start system.
The bypass module generates the signal normally sent from the BCM to the PCM/ECM when the proper key is detected. Without this signal, the fuel injectors will not work. Normally it costs between $150 and $300 to have this feature deleted from the PCM. By using our module you will accomplish the same function for less and you won't have to ship your PCM/ECM to have it reprogrammed.
This module will work for all PASSkeyII type engine computers made from 1986 to 2002. See our VATS FAQ page for a list of vehicles that used the PASSkeyII type VATS.
PLEASE NOTE: Any GM vehicle made from 86 to 93 may or may not need the 30 Hz version of our VATS bypass. For engine computers made from 86 to 93 we highly recommend that you purchase, or upgrade too, our DFVATS bypass (Dual-Frequency VATS), which has both the standard VATS signal type as well as the 30 Hz signal type, all in one module.
The VATS bypass module uses a simple three-wire interface (power, ground, signal).
A quick disconnect connector upgrade is available, so that the module can be easily remove to re-enable the factory anti-theft system and protect your car over night or at the car show. YOU CAN'T DO THAT IF YOU HAD YOUR VATS PROGRAMMED OUT OF YOUR PCM/ECM.
This module comes equipped with a status LED that indicates that it is functioning. Available LED colors are red █ , yellow █ , green █ , blue █ and white █. If a color is not specified you will receive red █.

Please note: If your vehicle (or engine's PCM/ECM) was made from 1986 to 1993 it may or may not need the 30 Hz version of our bypass module. Unless you know which you need we recommend that you purchase the DFVATS module which has both the standard as well as the 30 Hz signal types.
