Product Description
The DEI 556U immobilizer interface module (bypass module) is used when installing a remote starter in vehicles equipped with an RF (Radio Frequency) based immobilizer system. This type of system uses a small chip imbedded in the ignition key, called a transponder, to transmit a very low powered RF signal. This signal is detected through an antenna (or coil) around the ignition switch, which is then sent to the immobilizer's transceiver.Feature
Compatible with most alarms for wide-ranging use
