Security Code

The security code protects the immobilizer control unit against unauthorized programming and data access from Tech-2. The security code consists of a 4 digit code number and is programmed into the immobilizer control unit and Powertrain Control Module (PCM).

New control units are not programmed with a security code.

If the control units are replaced, the security code entered in the car pass, transponder ID, etc.

Must be programmed into the new control unit with Tech-2.

The security code can only be programmed with Tech-2 once and must therefore be performed with great care.

Once programmed, the security code cannot be overwritten. An already used immobilizer can be reused in a different car by initializing the immobilizer. After that you can program the security code again. For initializing command you need the current security code.

If the immobilizer control unit is returned (e.g. warranty cases), always enclosed the security code that is allocated to that control unit. If this is not done, we can not process the case and the warranty will not be recognized.
