This is used when installing remote start products in 1995 and newer BMW models equipped with the EWS II Immobilizer system. DEI 555B/DEI 556U (UNIVERSAL) Bypass Module for BMWThe DEI 555B EWS II immobilizer interface module (bypass module) is used when installing a remote starter in 1995 and newer BMW models equipped with the EWS II 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. Once the correct signal is received, the immobilizer will enable the ignition and fuel systems. NOTE: THE DEI-556U(UNIVERSAL) BYPASS WILL BE SHIPPED. THIS UNIT HAS REPLACED THE DEI-555B

Directed Electronics(DEI) is the world leader in remote start technology and has pioneered a series of modules designed to allow the original equiptment to work along side the add-on aftermarket security system or remote starter. These modules are known as ByPass Modules or Transponders, etc. These items are required items in the installation of any security system or remote starter and do not compromise the original equiptment in any way.
