I just bought a 1994 Saturn SL1 sedan, 118,000, 1.9 liter L4 engine. The description sheet that came with it when it was bought from the dealer also says: automatic lockup. I don't believe it has power locks, though.
The key will not lock or unlock the doors. The guy I bought it from said he locked his keys in one time and a friend of his opened it with a slim jim. Could that be the reason the key doesn't work and what should I do?
