Product Overview

XpressKit 556UXL Universal Remote-Start Immobilizer Interface Module with Selectable Windings for Larger Vehicle Keys

Expert Overview

The 556UXL Universal Remote-Start Immobilizer Interface Module by XPRESSKIT is designed for integrating remote-start systems into vehicles equipped with a transponder or RF-based immobilizer. This module addresses the challenge of immobilizer systems, which disable ignition and/or fuel if an invalid code is detected during a start attempt. The 556UXL specifically bypasses the vehicle's immobilizer only when the remote start function is active, ensuring the factory security system remains intact at all other times. It is a larger variant of the 556UW, engineered to accommodate larger vehicle keys that may not fit the smaller model. This product is suitable for IT hardware resellers and installers working with B2B clients who require remote-start functionality while maintaining the security protocols of their vehicle fleets. A spare vehicle key is required for its operation.
