The glove compartment in my 2000 Mitsubishi Montero sport was locked with the car key. When i tried to open it, the key will go in, but will not turn. I don't want to break the key off in there. Help!

Question edited for clarity. The word 'faub' does not exist - 'fob'.

Instructions for resetting the anti-theft system. The negative cable is always the one to disconnect first and reconnect last. You could also just phone for a mobile vehicle alarm installer / locksmith, or a mobile auto electrician.

In the link it say 5 times and then start the vehicle.

The rheostat is the little dial on the dashboard that alters the brightness of the dash lights. It isn't under the hood. If your turn it all the way down until it clicks, it will turn off the lights. It will be in your manual.

Did you check the fuse circuit for voltage? Use a test lite or something. The fuse circuit goes hot with key on. Even if the fuse is good, if no voltage on the fuse circuit, the circuit is still dead.
The wiring circuit in the steering column and horn switch are the ground circuit for the horn relay.

I believe you need to turn the key to on or push in the clutch pedal
Or brake if auto to release the safety lock.and be able to push the release button on gear lever

Will door key insert into lock cylinder? Usually exterior door lock cylinders may seize due to lack of use if using the key fob. You can use WD-40 and insert the straw into the lock and spray liberaly. Use the key in a sawing motion while applying turning pressure on the lock. This will normally free up any seized/sticky wafers in the lock assembly
