If it's an aftermarket system with a SKIM bypass...then the "ByPass" is probably an original SKIM key taped to the bottom of the SKIM antenna. Pull the plastic covers around the ignition switch and verify there isn't a key in there somewhere. If it was taped to the antenna and fell off out of range then it'll act like you're trying to start it with a non-SKIM key and trigger the anti-theft.
If by rare chance it does have an actual aftermarket SKIM bypass module that will need to be removed and the SKIM system put back to stock and repaired to working order. That means programming new SKIM keys and cutting them. Many locksmiths can do this cheaper than a dealer. Might need a new SKIM antenna module, etc.
