I cant get my doors to unlock with the key. I sprayed graphite in the keyhole an on 1999 Ford Taurus

and that didnt work. What kind of lubricant should i use to see spray in there and see if that will work and will it mess up because i already used graphite? Some times it works and sometimes it doesnt. It was raining hard and i accidently put a wrong key in. then ist stopped working. But i cant open the trunk or the passengers side either. So they stay unlocked for now
