Ordering Manual:

A: Can the store’s smart LCD key replace the original car key for controlling my vehicle?

Three conditions must be met: 1. Your vehicle must have factory-installed one-touch start functionality to be compatible with the smart LCD key. This must be the factory-installed one-touch start function, not one added through modification.

2. You must disassemble the original car key, remove the circuit board from the original key, and solder the circuit board to the LCD key’s wiring harness. The soldering must be done correctly and without errors to ensure the LCD key can perform the functions of the original key’s circuit board.

3. The LCD key only serves to change the appearance; it relies on the functions of the original car key circuit board. Therefore, before welding, you must use the original car key circuit board to open and close the car to test its functionality. If the original car key circuit board is ineffective, welding it to the LCD key will not work.

B: How do I weld the original car key circuit board to the smart LCD key’s wiring harness?

1. I do not recommend that users attempt welding themselves. It is advisable to take it to a mobile phone repair shop and have a professional use welding tools to perform the welding.

2. When welding, please carefully read the manual, which explains how to weld. Do not reverse the positive and negative terminals, as this will render the key inoperable. Many users lack welding experience and may accidentally damage the original car key circuit board due to unstable hands. Therefore, it is recommended to take it to a mobile phone repair shop for professional welding and avoid attempting it yourself.

3. Before removing the circuit board from the original car key for welding, it must be tested to ensure it can normally control the car, including turning it on and off, and that the functions are operational before proceeding with welding. Many customers bring in non-functional original key circuit boards for welding. The smart LCD key only changes the appearance; its functionality depends on the original car key circuit board, which is the core component controlling the vehicle. If the circuit board is non-functional, successful welding will be useless.

C: Can the smart LCD key enable all functions of the original car key circuit board?

The LCD key has only three wiring harnesses, meaning it can only activate three functions on the circuit board. Any additional functions on the circuit board that cannot be soldered will remain inactive. You will need to make a choice.

D: Can the smart LCD key change the wallpaper on the screen or customize the car logo?

None of the smart LCD keys have this functionality. The screen wallpaper is fixed and cannot be customized, nor can the car logo be customized.

E: My car has a one-button start function, but my original car key does not. Can the smart LCD key modify the function to enable the one-button start feature on my original car key?

The one-button start function is a method of starting the vehicle without inserting a traditional key. Simply carry the original car key into the vehicle, and the car will detect it. Pressing the one-button start button on the car will start the engine. Therefore, the one-touch start function is merely a feature on the car; it is a switch on the car. The car key states “no one-touch start function.” Some car brands’ keys have a remote start function; pressing the remote start function on the key triggers the car’s one-touch start function switch to activate. You must have the original car key with remote start functionality. You can only use our LCD key to modify the appearance; it is impossible to obtain remote start functionality through the LCD key.

F: How do I adjust the text on the smart LCD key to my local language?
