Creepy story, and I feel the pain.
I got a 2nd hand Smart with 2000 miles. Well, the horn doesn't work, the passenger door lock doesn't work, and heaven knows what else. I took it to the Mercedes Benz of Sugarland, Texas and they ordered a new SAM unit. Meanwhile, I also ordered a new key, because the car only came with one.
They called and said my SAM was in, and I can come in any time to have it installed.
Fifty miles one way, I got there and they took the car back, and then came and said that they can't put the SAM in without two keys. The second key is held up in customs. SOOOOOO I have to wait for the key to come in before they can install the SAM, and get the horn working.
My question is, what if I lose one of my keys, then what?
