EoneBoss / Key Unlockers
The TLK is a professional device designed for reusing locked Toyota/Lexus keys. Through innovative technology, it allows direct matching of used keys without unlocking them, significantly improving key reuse efficiency and reducing overall costs.
When a locked key is reused, the typical process involves unlocking and resetting it to a blank state. However, certain Toyota/Lexus key models cannot be refreshed due to unique encryption mechanisms. To address these challenges, the TLK device employs a breakthrough solution.

Operation Instructions
Step 1 – Simulate Key Generation
Place the original locked key in the TLK sensing area and press the button. TLK will read the secure identifier (e.g., key ID) and simulate a matching key using internal data.
Step 2 – Match to Vehicle
Use the TLK as a replacement key during the vehicle matching process. The device writes key ID and other information into the vehicle system while securely retaining key-related data.
Step 3 – Write-Back Operation
After successfully retrieving the data, TLK writes the complete key information back to the original locked key, reactivating it.
Final Confirmation
Once the update is complete, test the key to ensure all functions are working. Programming is now complete.
