Hello,

Well congrats on the Garage Door Fix.

Ok, couple other causes.

Bad Ignition Switch - location depends on if tilt steering or not and if shifter is on floor.

Bad Key Chip - in most newer vehicles there is a security chip in the key itself. If becomes damaged can fail and vehicle will not start. If have spare key try it.

Post results.

Turn ignition off. Disconnect Black, 48-pin connector C201 or Black, 56-pin connector C200 located on right side of steering column. Using DVOM, check for continuity between specified terminals with ignition switch in specified position. See IGNITION SWITCH CONTINUITY TEST table. See Fig. 1 and Fig. 2. If continuity does not exist as indicated, replace ignition switch.
