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 your vehicle by routing commands through its 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.

Nice Adapter for Chevrolet Traverse

Written By GregD, San Antonio, TX on Saturday, January 04, 2014

Crutchfield Customer Review (What's this?)

This is an easy to use interface kit. We used it to bridge a Code Alarm/Remote Start system to our 2011 Chevrolet Traverse. We were able to install this ourselves with minimal difficulty, as the instructions are clearly laid out, for almost every conceivable configuration. It was simple to install in the car and bypassed the stock theft deterrent system without difficulty. The casing was also small and easy to hide/secure ind the dash.

Pros: Easy to install. Easy to use. Conveniently bypasses and interfaces with stock computer system

Cons: While it works well with computer in the 2011 Chevrolet Traverse, Code Alarms/Remote starts do not use the D2D system, so additional wiring is required (although when wired it works the same).
