This is the most challenging part for DIY owners. Here are your three best options:
A Smart TAN code calculator is either:
The calculator works by asking for two critical inputs from your vehicle:
Once you input these into the calculator, it outputs the correct 3-digit TAN code. You then manually type this code into your car using the odometer reset button (press: enter digit; long press: confirm).
Check the Vehicle Identification Number (VIN) Plate: The VIN plate is usually located on the driver's side door jamb or under the hood. The paint code (also known as the "Lack Code" or color code) might be listed next to the "Lack" or "Color" designation.
Owner's Manual: Sometimes, the paint code is noted in the owner's manual.
Manufacturer's Website or Dealership: You can also contact a Smart or Mercedes-Benz dealership with your VIN, and they can look up the paint code for you.
If you have acquired a TAN code calculator (either via a mechanic friend or software download), follow this step-by-step guide:
I needed to program a second key. I tried a cheap OBD cable + “TAN calculator.exe” from a forum. It didn’t even connect. Then I paid a local locksmith $60. He plugged in his Autel IM608 (with active Mercedes subscription), requested the TAN online, and had the key working in 5 minutes. The TAN was 6741 — useless for anyone else, even with the same VIN.
If you have a legitimate TAN but the car rejects it, consider:
If you own a 2011 Smart Fortwo (or any Smart car from the 450, 451, or early 454 series), you have likely encountered a cryptic, three-number sequence flashing on your dashboard.
