Understanding Smart Car TAN Codes
TAN stands for Transaction Authorization Number. In the context of Smart vehicles (manufactured by MCC and Mercedes-Benz), these are unique 12-digit alphanumeric codes required by the STAR Diagnosis System (SDS) or similar diagnostic tools. These codes act as a security layer to ensure that only authorized modifications are made to the vehicle's Engine Control Unit (ECU) or Body Control Module (SAM unit).
For a 2011 model, which falls under the 451 chassis generation, TAN codes are typically required for:
Key Teaching: Registering new remote keys to the immobilizer.
Soft-touch Activation: Converting a standard transmission to fully automatic mode.
Cruise Control: Enabling the steering wheel stalks and software logic.
Paddle Shifters: Activating sport steering wheels with gear paddles. How a TAN Code Calculator Works
A TAN code calculator is a software utility designed to bypass the traditional route of purchasing codes directly from a Mercedes-Benz dealership. Dealerships often charge significant fees for these codes, and in some regions, they may be hesitant to provide them to independent owners or third-party shops.
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
To utilize a generated TAN code, you cannot simply use a standard OBDII scanner. You will need a more robust setup:
Multiplexer: Usually a Star C3, C4, or C5 interface that connects the car to a computer. Disclaimer: This article is for informational purposes
Diagnostic Software: Mercedes-Benz DAS (Diagnosis Assistance System) or Xentry.
The Calculator: Software that runs on a Windows PC to generate the codes based on the VIN. The Evolution of Smart Coding
It is important to note that for many 2011 and newer Smart 451 models, the diagnostic process moved toward "Online SCN Coding." This means that instead of entering a manual TAN code, the diagnostic computer connects to the Mercedes-Benz servers to verify the vehicle's configuration.
However, many enthusiasts and independent mechanics still use offline versions of DAS/Xentry. In these offline environments, the TAN code calculator remains a vital tool for bypassing server-side checks and enabling features locally. Risks and Considerations
While using a TAN code calculator is a popular DIY solution, there are several risks to keep in mind:
Software Integrity: Many calculators found online are "cracked" versions. Ensure your source is reputable to avoid malware.
ECU Safety: Incorrectly coding a vehicle can lead to "bricked" control modules. Always ensure your vehicle battery is connected to a stable power supply (battery maintainer) during the coding process to prevent voltage drops.
Legal/Warranty: Modifying your car’s software may void remaining warranties and could have legal implications depending on your local regulations regarding vehicle modifications. Conclusion
The "smart car tan code calculator 2011" remains a sought-after tool for the 451-generation Smart Fortwo. It empowers owners to customize their driving experience and perform necessary maintenance without the steep costs associated with official dealership visits.

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.
If you need key programming, skip the calculators entirely.
If you have acquired a TAN code calculator (either via a mechanic friend or software download), follow this step-by-step guide:
First, let’s decode the acronym. TAN stands for Tankentleerungsnummer, which is German for "tank draining number." When Smart (a subsidiary of Mercedes-Benz) designed the early microcars, they implemented an anti-theft and safety feature within the fuel system.
Here is the critical reality for 2011 Smart owners: The fuel pump will not run unless you enter a valid 3-digit TAN code into the instrument cluster. This is not a "check engine" light strategy. It is a hard fuel cut-off.
The system works as follows:
For the 2011 model year, this system is fully active. Later models (post-2014) started phasing it out, but the 2011 Smart Fortwo (both coupe and cabrio) relies entirely on this security handshake.
