Directed 556UW Universal Remote Start Interface Module
Directed Electronics 556UW Universal Immobilizer/Transponder Bypass ModuleThe 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, ed 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.Directed Electronics, DEI, 556UW, Universal Immobilizer, Transponder Bypass ModuleDirected Electronics, DEI, 556UW, Universal Immobilizer, Transponder Bypass Module
