Immobilizer Bypass Modules

warning! Any vehicle equipped with a fac- tory immobilizer must use an immobilizer bypass module to remote start. If not used, the vehicle ignition or fuel supply circuits could lock up and require a costly trip to the dealer to reset the computer system.

Most newer vehicles have a factory engine immobilizer system designed to prevent any unauthorized use of the vehicle. These immobilizers will cut off power to the starter and the fuel supply preventing a thief from starting the vehicle.

There are several types of immobilizers, with the most common being the resistance based passlock/passlock 2 systems found on most newer GM vehicles. This system can be bypassed using the 557L immobilizer bypass module available at your local retail dealer. The majority of transponder-based immobilizer systems can be bypassed using the 557U immobilizer bypass module available at your local retail dealer.

To determine what bypass module your vehicle requires, check your web vehicle information sheet.
