🛠️ Programming instructions

🔌OBD PROGRAMMING - DIAGNOSTIC TOOL REQUIRED

This proximity smart key cannot be learned by hand. It is registered to the car through the OBD-II port with a diagnostic tool.

Compatible tools: the BYD dealer system, or locksmith tools whose software lists this model, such as Xhorse VVDI Key Tool Plus, Lonsdor K518.

Add key (spare): enter the password from a VIN lookup or let the tool collect it from the car, then match the new key together with every key the customer keeps.

All keys lost: the tool collects the key data at the start button, or the dealer supplies the key ID and the tool collects the password, then the key is matched in the same session.

Blade: cut the emergency blade to the vehicle's key code and test it in the driver's door.

Check coverage first: support depends on the tool's software version and the exact model year. Verify the BYD F3, L3, F0 and G3 2010-2017 smart key is in the tool's supported list before the job.
