Our take on the XpressKit GMDLBP

by Ken Nail

XpressKit modules work with your vehicle's anti-theft system to incorporate the convenience, security and luxury features of your Python™ alarm system.

An XpressKit interfaces with vehicles by routing commands through your vehicle data system, so it's more secure. You have fewer wires to connect and, best of all, your extra key stays with you, not in your car.

Use the GMDLBP to interface with the alarm system in select 1997-up GM vehicles with anti-theft systems. The compact module comes with harnesses and a built-in transponder data interface port.
