How to Use EoneBoss TLK2:

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.
