If your current calculator generates wrong codes, consider applying a "tanlogfix" patch to your DAS installation (found on MHH Auto forums) or switching to a calculator version known to support 03/2011 DAS releases. Testing by forum member "sixcode" confirmed that a specific TAN generator worked on DAS 03/2011 version after applying appropriate fixes.

A calculator software program alone cannot talk to your car. To successfully code a 2011 Smart Fortwo, you need a complete hardware and software setup: 1. Diagnostic Hardware

The 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.

The DIY Smart community on remains active. If your calculator fails, post your VIN, desired function, and DAS version . Experienced members may generate the correct TAN code for you or guide you through manual editing of EEPROM dumps to bypass the requirement. smart car tan code calculator 2011

Modifying vehicle software parameters always carries inherent risks. Inputting incorrect strings or losing power midway through a flashing sequence can "brick" your SAM unit or ECU, rendering the car undriveable. Always ensure your diagnostic laptop and car battery are fully charged, and consider consulting a specialized European auto locksmith if you are uncomfortable managing the command line interfaces of diagnostic software.

The calculator works by asking for two critical inputs from your vehicle:

The mention of "2011" in the keyword isn't just a random year; it points to a significant transitional period. The official Mercedes-Benz diagnostic software, , was frequently updated. Users on diagnostic forums reported that older TAN calculator tools worked flawlessly on software versions prior to 2011 but began generating invalid codes for versions released in March 2011 and later. This created a pressing need for updated calculators capable of handling the new cryptographic challenges posed by DAS versions 2011, 2012, and 2013.

The TAN code is . It is generated externally by a proprietary Mercedes-Benz backend system (called NetStar or XENTRY Diagnosis’ backend). To get a TAN, a dealer or authorized locksmith must submit the vehicle’s VIN, the specific ECU’s identifier (e.g., EIS part number + serial), and mileage to the Mercedes-Benz servers. The server then returns a one-time TAN valid for a short window (often 24 hours) and for a single session. This is where the calculator concept enters.

The calculator works by using the vehicle's unique 17-digit Vehicle Identification Number (VIN). By inputting the VIN and the specific function you wish to activate into the software, the algorithm generates the corresponding 12-digit TAN code. This code is then entered into the diagnostic software (such as DAS or Xentry) to unlock the feature. Tools Required for 2011 Smart Models

The Smart Car, also known as the Smart Fortwo, is a compact two-seater vehicle produced by the German company Smart, a subsidiary of Daimler AG. The 2011 model year brought various updates to the Smart Fortwo, including changes to its engine, transmission, and features. One essential tool for Smart Car owners, particularly those who want to diagnose and troubleshoot issues with their vehicle's engine or want to know the engine code, is the Smart Car Tan code calculator.

Standalone "hardware" calculators have largely been replaced by online calculation services Official Route:

While older 450 models almost always required TAN codes, some later 451 models (2011–2016) can sometimes be programmed offline using patched versions of DAS that bypass the need for a TAN code.

The calculator generates codes for several critical maintenance and modification tasks:
