A Smart Car TAN Code Calculator is a specialized software tool used by mechanics and owners of Smart Fortwo (W450, W451) and Roadster models to unlock restricted features within the Mercedes-Benz diagnostic system, known as DAS (Diagnostic Assistance System). For a 2011 Smart Fortwo (W451)
, these codes are essential for performing advanced programming that the car's standard computer blocks for security reasons. Key Functions of a TAN Code Calculator
The calculator generates a unique 12-digit code based on your vehicle's VIN or a specific request code generated by the DAS software. Common uses include:
Key Learning: Programming new transponder keys or remotes to the vehicle.
Feature Activation: Unlocking dealer-only options like Cruise Control (Tempomat), paddle shifters (steering wheel gearshift), or Softouch (automatic gear shifting mode).
Hardware Syncing: Synchronizing a new or used SAM (Signal Acquisition Compilation) unit or ECU to the car.
Performance: Activating specialized Brabus Performance Tuning software. How to Use the Calculator
Connect to DAS: Connect your car to a Mercedes Star Diagnosis (MB Star) tool running the DAS/Xentry software.
Generate Request: Navigate to the "Special Functions" or "Retrofitting" menu. The software will display a "Request Code" or ask for a TAN.
Calculate: Enter this request code and your VIN into the Smart TAN Code Calculator software.
Input & Unlock: Enter the generated 12-digit TAN back into the DAS field to complete the activation. Important Considerations for 2011 Models
Version Changes: 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.
Software Access: These calculators are typically third-party tools found on automotive forums or sold by specialty diagnostic vendors; they are not officially provided to the public by Mercedes-Benz.
If you are trying to program a key for your 2011 Smart, you might also consider using modern handheld tools like the Autel KM100 or XTool D7, which can often handle key learning via the OBD2 port without needing a separate TAN calculator.
Are you trying to program a new key or activate a feature like cruise control? Do you already have a diagnostic tool (like MB Star/DAS)? SMART TAN Code calculator for DAS
Mercedes-Benz has been phasing out TAN codes for newer vehicles (2018+), replacing them with online authentication via XENTRY Pass-Thru – essentially, the car phones home directly. But the 2011 Smart Fortwo remains in the TAN era. As long as these cars stay on the road, the TAN calculator – whether a dealer’s backend or an aftermarket tool – will whisper secrets to the SAM unit, allowing keys to be born, immobilizers to sleep, and 12-year-old city cars to start another day.
For the 2011 Smart owner, the lesson is simple: respect the TAN, keep your dealer’s number handy, and never lose your last working key. Because without a TAN, that quirky two-seater becomes a very small, very expensive sculpture.

Third-party calculators rarely work for the 2011 451 generation because the system uses cryptographic challenges.
If you have a link to that specific post or more context (was it about key coding, ECU replacement, or window tint?), I can give you a more precise analysis or verify whether the method works.
Smart car owners and technicians often encounter a common hurdle: the need for TAN codes to activate specific features or perform key programming on models like the 2011 Smart Fortwo. Whether you are adding a new key fob, enabling cruise control, or configuring a soft-touch gearshift, understanding how TAN codes and calculators work is essential for maintaining these compact German vehicles. 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: smart car tan code calculator 2011
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.
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.
