Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.
Is this an OEM or aftermarket alarm?
Will the vehicle crank and start?
What does the theft light do with the key on?
Camping and have no phone service, but there is free wifi here. Sorry I can only type. You can request a call and another can fulfill it.
Since the theft light is not on with the key on, this means it should not be a theft system issue. more so related to the ignition switch, transmission range sensor, starter relay, or starter motor. Can your mechanic read wire diagrams and do wire testing with a volt meter?
