How to Replace the Battery in an Emgrand Car Key?
2 Answers
To replace the battery in an Emgrand car key, follow these steps: 1. On the side of the remote, there is a button for the mechanical key. Press this button and pull out the mechanical key. 2. After removing the key, you will see the word "open" in English on the front of the key, along with a small protruding area. 3. Insert a screwdriver into the small gap—choose the larger gap—and turn the screwdriver clockwise to pry open the casing. 4. If the key has two layers, continue prying it open, then gently separate the layers to reveal the battery and the key's circuit board. 5. Insert the screwdriver under the battery and gently lift to remove it. Then, insert the new battery securely and reassemble the key in the correct order.
My experience with changing the battery for my Emgrand car key is: Use a dime to insert into the small gap on the back of the key shell, gently pry it open to separate the two halves. The button battery inside is model CR2032, be careful not to shake it when removing to prevent the contact points from shifting. Buy a new battery of the same model, available at supermarkets or online, and place it back with the plus side facing up. After closing the shell, press it firmly with your hand until you hear a click indicating it's locked. Remember to test the remote door-opening function after replacement to ensure it works properly. If the buttons don't respond, the battery might be installed upside down. It's quite easy to do it yourself. Keeping a spare battery in the car drawer can help deal with sudden power loss. The whole process takes no more than five minutes without any tools, saving the cost of visiting a repair shop.
