My experience with changing the 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.
