Problems with ours too. Usually can't get the lock to light up so we can enter code. Then when we do get to enter the code doesn't lock/unlock. Didn't think there was a left and right to the keys, just one key for both numbers reducing possible codes. I think (but could be wrong) that code 1-1-1-1 is the same as 2-2-2-2 is the same as 1-2-1-2… you get the idea. Will have to do some research - no manual provided by Jayco.
