Try to start the car with all the keys that the customer has.

Does the car start with all keys?

Yes - Fault-tracing information

No - Programming keys

-------------------------------------------------

Fault-tracing information
The control module has previously read and not approved a transponder code because it was not stored in the memory. That can be because of the following:
- There are several Volvo keys with transponders to the same car or other cars on the key ring. The control module reads the key code from the wrong key or a mixture of codes from several keys when attempting to start the car.
The keys should hang free so that they do not affect the key being used.
- Attempts have been made to start the car with a Volvo key which is already programmed to another generation 3 immobilizer.
- Attempts have been made to start the car with a Volvo key before it was programmed into the control module as an approved key to the car.
- Attempts have been made to start the car with a Volvo key that is not one of the approved keys for the car.
- The fault occurred because of temporary interference in the communication between the transponder and the control module.
