If you own a 2011 Smart Fortwo (or Forfour), you’ve probably seen the dreaded “TAN required” message when trying to program a new key, disable the speed limiter, or reset the radio. You might have searched for a “2011 Smart car TAN code calculator” — and landed here.
Let me save you hours of frustration: There is no working “TAN calculator” for a 2011 Smart car that you can download for free.
Here’s why — and what actually works.
The Smart Car TAN Code Calculator 2011 is not a luxury—it is a specialized key to your car’s fuel system. Unlike earlier Smarts, the 2011 model year introduced enhanced security that locks out generic solutions. Whether you purchase an Autel scanner, download a verified software tool, or befriend a Mercedes tech with XENTRY, you need this calculator before attempting any fuel-related repair.
Final Pro Tip for 2011 Owners: Before you drain the tank, generate the code with the calculator twice — once before turning the ignition off and once after. The SAM unit sometimes rolls the seed during power cycles.
Keep your calculator software on a dedicated USB drive labeled "Smart 2011." When that dreaded "TAN ---" appears on your dash, you will be ready. And you will have saved yourself a $200 tow and a $300 dealer diagnosis.
Disclaimer: This article is for informational purposes. Modifying your vehicle’s fuel or electrical systems carries risk. Always consult your vehicle’s service manual and local regulations.
The short answer is yes — unless you plan to never service your fuel system.
Here are the repair scenarios that require TAN activation on a 2011 Smart:
A mechanic without a TAN calculator will likely refuse the job. A dealer will charge you 1 hour of labor (typically $150-$250) just to punch in the code — on top of the actual repair.
Buying a $50 used iCarsoft (if you can find one) or a $20 software license pays for itself the first time you need to drop the tank.
There is one legitimate use: radio unlock codes (not TAN for immobilizer). For a 2011 Smart’s stock radio (e.g., Alpine unit), you can calculate the code from the serial number. Some websites do that for $5–15. That’s not a “TAN code” — it’s a radio PIN. Check the Vehicle Identification Number (VIN) Plate :
If you need key programming, skip the calculators entirely.
