Immobilizer functions: AURO Otosys IM100 and IM600

auto key programmer

What’s the main different of AURO OtoSys IM100 and OtoSys IM600:

The main difference lies in Mercedes-Benz, VW, Audi software and adapters to work with.

Software difference:

Auro IM600 can read PIN/CS from AUDI Q5/A4/A5 2015-2017 and learn keys to Mercedes-Benz, but IM100 cannot work with Mercedes-Benz, VW, Audi for immobilizer functions.

Adapter difference:


IM600 use UP400. IM100 use UP200.

Up200 doesn’t allow for eeprom and use of breakout leads through the custom pinouts.

Edit to update: IM100 is confirmed to have luck with Mercedes-Benz immo.


Now Otosys IM100 with UP400 can work for Mercedes key programming as well as Otosys IM600 does.
