At least you still have ONE key. Saabs from about 2000 or so have a alarm module that talks to the engine & chassis computers, & each one of those computers "knows" the car's VIN and which keys are authorized. If you lose the last key, not even the dealer or the factory can re-program it. So the $1200 security computer becomes a paperweight... in addition to needing new keys.

This is called "PROGRESS". My 72 Datsun starts looking better & better.
