How to Replace the Battery in a Volkswagen Lavida Key?
2 Answers
Prepare the Volkswagen Lavida car key. Separate the smart key from the mechanical key by pulling the key apart with your hands or using a screwdriver to pry it open. Use your hands to separate the circuit board from the battery-containing part in the middle of the key. After separation, carefully remove the battery from the panel and replace it with a new one. Finally, reassemble the key by reversing the previous steps.
I've been driving a Volkswagen Lavida for several years and have replaced the key battery several times. There's a small seam on the side of the key case, which can be opened by gently prying with a flathead screwdriver or a coin. Be careful not to use excessive force, as the plastic clips are quite fragile. The button battery inside is a CR2032, which is available in supermarkets. When removing the old battery, pay attention to the positive and negative markings, and install the new battery with the silver side facing up. When closing the case back to its original state, you should hear a click to ensure it's securely fastened. After replacement, remember to test the lock and unlock buttons for responsiveness. The key battery typically needs replacement every one or two years. If you notice the remote control distance shortening or the buttons not responding, it's time to replace the battery. Also, avoid keeping the key and phone together, as electromagnetic interference can drain the battery faster.
