I have received no response what so ever from your "Expert" to date.
I wish you to continue to try to answer my question.
I have not found an answer to date from any other source.
I understand it would need a revised schedule of the code to the ESL to allow by pass of the steering lock. Considering it can happen due to a defect in the key the steering will remain locked. There should be a procedure to by-pass the ESL In these circumstances, especially as an inadvertently dropped key on to a hard surface key can cause the problem. It would be well worth while to have a bypass facility. If you are in the middle of no where and you drop your key it can cause the key to malfunction, while still ok to start engine and lock doors.
I accept with thanks, ***** ***** that there is apparently no procedure available and it is useful knowing that. The cost of key replacement at 300 Euro also long time period to obtain replacement key is a nuisance.
