The anti theft system will not allow my vehicle to start. The horn continually blows even when pushing in on the cruise control button. The light to the left of the steering wheel will not stop blinking. Any ideas, my only option at this point is to have it towed to the dealership.

 

Welcome to the forum
do a search of the forum as this sounds real similar to some other users...
I'll search also and see what I can find...

 

You might try disconnecting the battery for about 10min see if it will reset, also use the remote to lock and unlock the vehicle.
