Immo Bypass

ECU Files

ECU files are the core of Immo Bypass.
Each solution consists of files - original and modified dumps that can be
downloaded and programmed into your ECU.

Immo OFF

IMMO OFF Files are the majority of our database. These files can be used To permanently remove immobiliser signal in a vehicle.

Virgin / Syncro

Clear your ECU and restore it to factory settings, allowing you to adapt it to another car.

Emulator

Some solutions require installing an emulator in the ECU. Immo Bypass has ready-to-use files and instructions to make the procedure easier.

Key Writing

Program the values of the key code into the ECU memory.

PIN

Sometimes it is required to have a security access code to an ECU. PIN solutions in Immo Bypass explain how to calculate this code.

Impressive database, don’t you think?

Every file is 100% tested & working
Every file is downloadable
Ordered and easy-to-find files
