I strongly suggest allowing a technician to inspect the vehicle’s electrical system as it may simply be wire out of place or a blown fuse causing the vehicle not to start.

However 90% of immobilizer system repair and reprogramming must be performed with specialized computerized equipment that is only available at the dealer.
