Every morning the passlock sensor locks us out of the car until the engine warms up, usually about 30 minutes of trying to get it to work. Also, the check engine light comes on randomly and sometimes kicks on when the cruise control is on. We have tried the passlock 30 minute reset and it doesn't work. The alternator and battery are both new also. What is the issue?

the security-related fuses are typically located in the underhood fuse block. Here's how you can locate the fuse block and the specific fuse for the security system:

Check out the diagrams (Below). Please let us know what you find.
