It is most likely that your vehicle has set a theft deterrent code in the computer system & the computer is keeping the vehicle from starting.The vehicles PCM,BCM & theft deterrent module should be scanned for failure codes & view data of door & ignition input sensors .If the problem is intermitten the codes can be cleared & vehicle started,but it will happen again.

This problem can be a faulty sensor,module ,or ignition switch sensor.
