I didn't know that worked like that when you pull out the key! The key lock on the outside door handle also functions properly with the door locking and unlocking.

Yamae, on the dome light bulb, I took that out and tested it with the volt meter continuity tester and it did not show continuity. The metal end was barely hanging on and broke loose when I carefully removed it. Hopefully a new bulb will fix that issue also. Thank you for your suggestions also!

Glad it worked out for you! I learned the hard way about fuses when my amp was constantly in 'protect' mode... checked continuity on the fuse and voltage (amp was off) and it was fine, 12V. Speaker was fine. So I bought a new amp... same issue, WTF? Ended up discovering as soon as the amp powered on, voltage dropped to 8 volts. The fuse had become a resistor once current passed.
