Step 1 – Simulate Key Generation
Place the accidentally deleted or locked key in the TLK2 sensing area and press the button. TLK2 will read the secure identifier (e.g., key ID) and simulate a matching key using internal data.
Step 2 – Match to Vehicle
Use the TLK2 as a replacement key during the vehicle matching process. The device writes key ID and other information into the vehicle’s system while storing key-related data such as passwords.
Step 3 – Write-Back Operation
After successfully retrieving the data, TLK2 writes the complete key information back to the original locked key, reactivating it.
Step 4 – Final Confirmation
Once the update is complete, test the key to ensure all functions are working. Programming is now complete.
