My 80 year old mother's 93 Gran Prix has suddenly gotten very hard to
turn the ignition key to start it in cold weather. It's not hard to
turn when warmed up but she only drives it short distances (church, etc)

I used to own a '91 and a '92 Grand Prix, neither of which had the key
security system. As far as I can remember, 1994 was the first year the Grand
Prix's had them. That's also the first year air-bags were put into the dash
