one of your sensors is not working properly, so the door unlocks again. attempting to lock it a second time will work.
go ahead, try it. open a door and try the central lock. the doors will unlock. do it again, they'll stay locked.
2. the key turning with trouble could either be a problem with the tumbler, or more likely your key is worn or slightly bent. Your door locks, all hinges, etc. should be oiled up with every inspection 1 and 2. If you haven't done it recently, that's probably the reason you're now having problems.
1. So basically the sensors are finished and they think that there's a door that's open? I guess I can pick those up at the dealership, right?
2. I'll try using my 2nd key, see if it still screws up. I haven't done any inspections at the dealership since i've owned the car, so I don't think anything has been oiled up. Should I bother oiling up or do I need to change parts at this point?
