1. Please prepare an original remote control key.
2. Open the remote key, take out the circuit board.
3. Take out the wiring harness and connect them correctly according to the color of the rubber ring.
4. Solder the corresponding wiring harness on the circuit board battery position. The red wire is positive (+), the black wire is negative (-).
5. Solder the wiring harness - unlock, lock, trunk and multi-function correspondingly on the original key circuit board, please note the solder on the foot of the button, and there is no need to separate the positive and negative.
6. Plug the wiring harness with the circuit board soldered in the correct direction on the LCD key.
7. Sponge padding under the soldered circuit board.
8. Close the LCD key and fix it with screws.
9. You need to make sure the circuit board chip is facing out, avoid blocking the received signal. Otherwise, the comfortable input function will be affected
Non-destructive installation:
-During assembly, you only need to take out the original PCB board and solder the wires with each button, then put behind the LCD key, after using the LCD key.
-If you don't want to use our key, you can remove all wires and put it in your original key box. This allows a non-destructive installation

Important Notice: Before making a purchase, please read the order manual first to avoid returns or exchanges.
A. Can this smart LCD key from the store replace the original car key to control my car?
The following three conditions must be met:
1. Your car must have a one-key start function when it was manufactured, in order to be compatible with the intelligent LCD key. This one-key start function must not be an aftermarket modification.
2. You need to disassemble the original car key, remove the circuit board of the original car key, and solder the circuit board onto the wiring harness of the LCD key. There must be no errors in the welding and it must be done correctly, so that the LCD key can carry out the functions of the circuit board of the original car key.
3. The LCD key only serves to change the appearance of the new vehicle. It relies on the functions of the circuit board of the original car key. Therefore, before welding, the car must be turned on and off using the circuit board of the original car key to test its functionality. If the circuit board of the original car key is invalid, welding it to the LCD key will not work.
---------------------------------
B. How can I solder the circuit board of the original car key onto the wiring harness of the smart LCD key?
1. I do not recommend that users attempt the welding themselves. Instead, it is suggested that they take the phone to a repair shop and have professionals use welding tools to perform the welding.
2. When welding, please carefully read the instructions. The instructions explain how to perform the welding and avoid connecting the positive and negative poles incorrectly, which can prevent the device from functioning properly. Many users lack welding experience and attempt to use the welding tools themselves, which can cause instability in their hands and result in damage to the original vehicle key circuit board during the welding process. Therefore, it is recommended to take the phone to a repair shop and have professionals perform the welding. Do not attempt to operate it yourself.
3. Before removing the circuit board of the original vehicle key for welding, it is necessary to test the circuit board to ensure that it can control the car properly, turn it off and on, and that the functions are effective. Then, proceed with the welding. Many customers attempt to weld with invalid original key circuit boards. The smart LCD key is only a change in appearance; its functions depend on the circuit board of the original vehicle key. The circuit board is the core that controls the car. If the circuit board is invalid, even if the welding is successful, it will be of no use.
-------------------------------
C. Can the intelligent LCD key enable all the functions of the original vehicle key circuit board to work?
The LCD key has only 3 wiring connections, which means it can only activate 3 functions on the circuit board. The other functions on the circuit board that cannot be soldered cannot be activated. You need to make a choice.
----------------------------------
D. Does the intelligent LCD key allow changing the wallpaper on the screen and customizing the car logo?
All the intelligent LCD keys do not have such functions: they cannot set the screen wallpaper or customize the car logo.
----------------------------------
E. My car has a one-key start feature, but my original car key doesn't have this function. Can the smart LCD key change the function to enable my original car key to have the one-key start feature?
The one-key start function of a car is a start method that does not require inserting a traditional key. One only needs to carry the original vehicle key and enter the car to be detected by the car. By pressing the one-key start button on the car, the vehicle can be started. Therefore, the one-key start function is merely a feature of the car, and it is the switch on the car. On the car key, there is a statement saying "There is no one-key start function". For some car brands, the car keys have remote start functions. By pressing the remote start function on the car key, the one-key start function switch of the car can be triggered to open. You must have the remote start function on the original car key itself. You can only use our LCD keys to modify the appearance, and it is impossible to obtain the remote start function through the LCD keys.
