7.5.3. Procedure of reprogramming of an immobilizator

If all of you cannot reprogram an immobilizator yet, check quantity of working keys.

Replace a key or perform the procedure of reprogramming with addition of keys.
For production of a twirl or replacement of an element of an immobilizator (a key and/or the PCM block), the client has to bring to the dealer all keys.
It is connected with the fact that previously programmed identifiers of keys are erased from memory of the PCM block at repeated programming.
It is impossible to rearrange the PCM block from other car. Otherwise the engine will not be started.
Do not replace the PCM block new to check by search of malfunctions. The identifier of a key and the code word will be programmed in the new block, and it cannot be used for other cars subsequently even if you find out that the old block is serviceable.
The immobilizer cannot be disconnected.
Make sure that all registered keys allow to start the engine after the procedure of reprogramming. Wait for not less than 5 with before use of the following key.
When the client does not need to register more than two keys, the following operations can be stopped after registration of two keys.
