How to replace the car key shell

After releasing the key sheet, use a smaller screwdriver to insert it into the side groove near the key sheet, and carefully push the screwdriver in the direction of the key sheet (arrow direction). The key sheet is separated from the chip box. Insert a flat-blade screwdriver into the groove on the side of the chip case and rotate to separate the housing snaps there. Then insert a flat-blade screwdriver into the groove at the top of the chip case and rotate to separate the case snaps there. Separate chip box with CR2032 battery on the left and chip circuit board on the right. The white rubber pad around the chip board should be waterproof.
It is not difficult to install, just put it in the key case.
If you have strong hands-on ability, you can buy a key shell online. This question still needs to be asked. Your hands-on ability is definitely not good. You should find a professional locksmith to do it.
