Question about my 98 Camry

I need some help. For one I have to apologize because I posted a question in the introduction part. :screwy: I really love my car but I have a problem that I need help with...I can lock my car with only the key on the drivers side but can't unlock it. Then on the passenger side it is the opposite, it unlocks but not locks. Has anyone ever had a problem like this that can help me...It is really getting to be screwed up. :banghead: I am divorced and have worked on my own cars for a while now but this situation I just can't figure out...Thanks

With any kind of luck, this is probably just a lubrication issue. Try spraying some penetrating oil or graphite lube into the lock cylinder and work the key back and forth.
