How to disassemble the car key and install the battery?

1. Unscrew the middle screw of the car key chain with a screwdriver.

2. Unpack the car key holster and key ring, and check that there will be a button around the key (all kinds of cars are similar). After pressing it, you can take out the key.

3. Open the lid on one side, and be careful not to use too much force. Some keys are buckled and can be broken on both sides. Some keys are slippery and need to be pushed out.

One side of the battery is stuck, so we need to pry open the bottom of the other side of the battery with a screwdriver and take it out.

5. Pay attention to the details of installing the battery, first insert one end of the battery, and then press the battery by hand.
