Navigator, I just broke into mine because there were no keys. (Long Story
). The service manual tells you how to do it, but the quick and dirty way is to disassemble from the inside and take it to a lock smith. They can remove the tumblers very quickly and duplicate you a key, or install a new one with a new key. There should be 3 screws on the inside and 2 on the latch side. Security wise it doesn't take much to break in. I have seen some posts about installing aftermarket deadbolts. This appears to be a better locking method. LOL, Kim
