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.

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

March 28, 2014

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!

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.

Can always count on DEI

February 14, 2013

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.

For vehicles that aren't controlled completely by data, these bypass kits are amazing. The 556U is hands down the best "hide a key" style unit you're going to get. I recommend it every time and as a professional installer, I use it when possible.

will this bypass my security theft sensor on my 06 chevy cobalt, my car will currently not start?

Best Answer: I buy 556Uw but I don't need it for my type of car. I have a Suzuki Vitra S 2015 model with keyless entry. Unfortunately tehnicians from auto service told me to buy 556Uw, but when they mount my 5706V, they realised that they don't need the 556Uw module. In most cases 556Uw is needed. I think you must ask a good tehnician or Directed if for your car model need this module. Hope it helps :)
