When a vehicle refuses to start , especially if the cause is an immobiliser-related issue , it can be a frustrating situation for both the motorist and the technician who is entrusted to solve the problem . Immobiliser systems are intricate and often integrated with a vehicle ’ s electronics , using a combination of technologies such as radio frequency identification ( RFID ), transponders , or unique codes to prevent ignition . The complexity of these systems makes diagnosing problems more challenging , so overcoming immobiliser issues requires specialist knowledge and tools .
