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.

Awsome!

Directed 556U Immobilizer works like a charm! I turn heads every time I remote start my car and one one is inside!

It's a must have for connivance. Cool your car on a HOT day or HEAT it up on a cold night, your car is at the perfect climate every time.

Great price, great product for my Avital 4400 in 01 Audi A6

Flawless with zero failures since installed one month ago. I was able to locate the factory wiring to tap into on my A6 instead of using the suppliedring. Good clear instructions. Does what it is supposed to do, not much more to ask for!

Can always count on DEI

The first alarms I learned how to install we're viper, python, avital, etc. all dei products. So naturally it was DEI modules I would use for oem interface. This particular module is an oldie, but seeing as my car is an oldie (2000 3 series BMW ) I found myself in need of this exact module. What I really like about the 556u is that is has more than one option as far as connectivity and oem interfacing goes. This things work like it shoul and is really inexpensive compared to newer style transponder bypass modules.
