After 3 years of ownership i tried the keys that came with the car.
NONE WORK
Lucky i tried them before a battery failure.
Anyone else try there keys ?

FWIW, My key works in mine, although I can only seem to unlock it but not lock the door? I guess you can do it from inside the door then shut it, but it's just different.

Battery dead twice. Key worked both times to unlock door.

Tried my keys and can not turn the lock without using a big pair of pliers. Lincoln says they can not help me. Not to happy with Lincoln!
Time to return to Buick where I was happy.
