Hello all,
I hope you can help. The driver door will not lock or unlock manually with the key. As a matter of fact the key will not turn in the door lock. The remote lock/unlock works fine. Any clues of what's going on here?

Buy a can of silicon spray and lube the lock, stick the key in and turn it several times do this every 6 months.
Also remove the LR emblem off the cargo door and lube the latch, open the cargo door and lube the door slide too.
Bike chain lube works best for the door slide. (that is the thing under the door that keeps it from opening to far)
