This universal TK800 LCD key supports keyless-go, offers an anti-loss feature, and provides convenient control right from your palm. It’s engineered for vehicles that already use a one-key start function, helping you regain easy access, start the engine, and manage basic security features without fumbling for the correct remote.

Engineered for wide compatibility, the TK800 LCD Key works across a broad range of models and brands while presenting a clean, logo-free exterior. It’s designed to be user-friendly with a responsive touchscreen, and it supports multiple languages to help drivers around the world customize the device to their preferred language. Installation requires basic soldering of the original key circuit board to the LCD key, with an installer capable of completing the process in about 15 minutes when using OBD access.

Note: This product does not include car logos or stickers. It is intended for vehicles with one-key start and may not support every function on every model.
