    You 1st have the car towed to a dealer and have the ignition lock replaced then the module must be programmed to accept new lock cylinder.

How much does it cost to replace an ignition key for a 1991 Ninety-Eight Oldsmobile Regency?


It depends on your area. You can replace the ignition switch portion yourself. However the key lock has a chip on it that tells your cars computer it is ok to start. The dealer will have to re-program your cars computer to tell it that that key lock cylinder is ok to start the car.

1991 Oldsmobile Ninety Eight Regency I can't determine how mice are getting into the car. They are inside the car; I.E. under the seats,in the glovebox, in the trunk, etc. I put a screen over the air...


Get some dryer sheets and moth balls and put them all over where the mice are.They will leave.They don`t like the smell.I can`t tell you where they are getting in because I don`t know but you will have to look around the vehicle and see if you can find a hole.It does not take a very gig hole either.Hope this helps.Good luck.
