The car is completely unusable right now. They told me it's going to cost $1,300+ in parts and labor to replace the SAM control unit. They also mentioned this is a "fairly common" problem that occurs when programming new keys, and that ours is the "second or third time it's happened".

The car was fully functional before I brought it in to have the new key programmed, and now it's dead until I pay for the replacement parts and labor.

I'm prepared to eat the repair bill, but I was wondering if anyone else had any experience or advice regarding this issue before I do.
My Smart has not been starting properly why is located in another place. I have been getting messages like, engine malfunction, remove key, take to service shop, four wheels need to be off ground ?, etc. it has shut down in traffic, refused to start then a little later it starts as normal. Any problems like this ?

MB/smart isn't the only one being ridiculous like this. My girlfriend's Honda Civic has a built-in navigation system. A sharp eye will take note that the system is literally just an Android tablet with a Honda skin on it. Well, while troubleshooting why Android Auto wasn't working by resetting the unit, it managed to freeze. Buttons weren't working, the screen was flickering. It was essentially bricked.

Honda suggests replacing the whole unit to the tune of $1+k.

Then I remembered that the thing is just an Android tablet, and it probably just needs to be restarted. Since the buttons don't work and there isn't a battery to run dead, I checked the fuses up front, pulled the one for the system, then put it back in. Headunit rebooted and had no further issues.

Our original problem turned out to be bad USB ports on our phones, but it could have gotten far more expensive if Honda got involved.

That just makes me angry to hear that.

Yes, I understand the need for digital electronic IC engine controls so an engine can operate at the perfect state of tune (ignition timing, exact stoichiometric A/F ratio) in order to meet stringent emission requirements. but what kind or economic insanity has allowed to to accept manufacturers giving us cars where the mere act of unlocking a door or turning on a headlight is tied to a device that can render the car inoperable if it fails?

Pete000 Dealer broke it, Dealer should fix it. I hear so many horror stories about MB dealers.
