If you now have a key that fits the door you will have to hook up all the wires back to normal. After this is done, disconnect the battery and wait at least ten minutes. With all of the doors closed and locked, reconnect the battery. Unlock the driver’s door and see if the ignition turns and starts the vehicle. If the theft light is still flashing then try and unlock the drivers door to see if the alarm stops and the vehicle starts. If it now starts then the drivers key lock cylinder will need to be replaced.

If you need some assistance with these checks, consider enlisting a qualified technician who can diagnose your starting issue and perform the necessary repairs to your vehicle to get it going again.
