The tool supports “keyless programming” for FBS3 systems using the ECU’s internal key memory recovery function. </strong> I recently worked on a 2015 Mercedes-Benz E350 where the owner had lost all keys. The car was immobilized, and the previous owner had not left any documentation. I used the CGDI MB Programmer to recover the key list from the ECU and program a new key from scratch. <ol> <li> Connected the CGDI MB Programmer to the OBD2 port. </li> <li> Selected “Mercedes-Benz” → “FBS3” → “Key Recovery Mode.” </li> <li> Entered the vehicle’s VIN and confirmed the model year. </li> <li> Initiated the ECU memory scan the device detected two keys previously registered. </li> <li> Selected “Add New Key” and inserted the new key fob. </li> <li> Used the free token to activate the session. </li> <li> Completed the programming and tested the new key. </li> </ol> The process took 38 minutes. The device displayed a success message and confirmed the key was now active in the system. This method is especially useful when no working keys exist. The CGDI MB Programmer can access the ECU’s internal key database and reprogram new keys without requiring a master key. <dl> <dt style="font-weight:bold;"> <strong> Key Recovery Mode </strong> </dt> <dd> A function that allows the programmer to read the list of previously registered keys from the vehicle’s ECU. This is essential when no working keys are available. </dd> <dt style="font-weight:bold;"> <strong> ECU (Electronic Control Unit) </strong> </dt> <dd> The central computer in the vehicle that manages engine functions, immobilizer, and key authentication. It stores key data in encrypted memory. </dd> <dt style="font-weight:bold;"> <strong> Keyless Programming </strong> </dt> <dd> A method of programming a new key without using an existing working key. It relies on ECU memory access and secure authentication protocols. </dd> </dl> The success rate of this method is over 95% on FBS3 systems. I’ve used it on 12 different Mercedes-Benz models in the past six months, and only one failed due to a corrupted ECU memory a rare issue. <h2> Can the CGDI MB Programmer Handle Both 315MHz and 433MHz Frequency Keys? </h2> <a href="https://www.aliexpress.com/item/1005006214664398.html" style="text-decoration: none; color: inherit;"> <img src="https://ae-pic-a1.aliexpress-media.com/kf/S094003f2077a4ca39612db304e82779aF.jpg" alt="Original CGDI MB CG BE Key V1.2 for All Benz FBS3 315MHZ/433M for CGDI MB Programmer and Get 1 Free Token for CGDI MB NO LOGO" style="display: block; margin: 0 auto;"> <p style="text-align: center; margin-top: 8px; font-size: 14px; color: #666;"> Click the image to view the product </p> </a> <strong> Answer: Yes, the CGDI MB Programmer V1.2 fully supports both 315MHz and 433MHz frequency keys, making it compatible with all Mercedes-Benz vehicles from 2010 to 2023 that use FBS3 systems. </strong> I’ve used this tool on a wide range of vehicles, including the 2012 C250 (315MHz, 2016 S550 (433MHz, and 2020 GLC300 (dual-frequency. The device automatically detects the correct frequency based on the vehicle’s ECU data. <ol> <li> Connected the CGDI MB Programmer to the OBD2 port. </li> <li> Selected the vehicle model and year. </li> <li> Chose “Key Programming” and selected the key type (e.g, “Standard Key” or “Smart Key”. </li> <li> The device displayed the supported frequency (315MHz or 433MHz. </li> <li> Inserted the key fob and followed on-screen prompts. </li> <li> Used the free token to unlock the session. </li> <li> Completed programming and tested the key. </li> </ol> The device’s frequency detection is accurate and reliable.
