🔓 KESS3 Unlock Module – BOOT Glitch Unlock for Bosch MD1 / MG1 ECUs, Finally Within Reach 🛠️⚡

The KESS3 Unlock Module is the new original Alientech accessory that makes it possible to perform the Glitch unlock procedure in BOOT mode on locked Bosch MD1 and MG1 ECUs. Once the ECU is unlocked, KESS3 can read and write in BOOT mode, and then in BENCH mode using the dedicated solutions in Alientech Suite. An essential tool for every remapping professional who wants to work on the latest generation of Stellantis, VAG, Ford, Jaguar/Land Rover and Kia/Hyundai ECUs. 🔧🚗

💡 Why Choose the KESS3 Unlock Module?

✔️ Access to locked ECUs 🔓: unlock Bosch MD1 / MG1 ECUs that were previously out of reach and expand your service offering.
✔️ Original Alientech module 🛡️: KESS3 only works with the official module — non-original modules are automatically detected and blocked.
✔️ Not tied to a serial number 🔁: the module is not linked to a specific KESS3 and can be used with different compatible KESS3 tools.
✔️ Complete, ready-to-use kit 📦: Hardware Unit, ribbon cable, 14AS00T12S adapter and all the accessories needed for the procedure.
✔️ Read and write in BOOT mode ⚡: once the ECU is prepared, the BOOT protocol allows full read and write operations.
✔️ Immediate return on investment 💶: offer an unlock service to your own customers and pay off the module from the very first jobs.

🚗 10 BOOT Glitch Protocols Available

⚠️ Important: these protocols appear in green in Alientech Suite for eligible customers, but a protocol shown in green does not mean the operation can be performed with KESS3 alone. The KESS3 Unlock Module is mandatory to perform the unlock.
