How to Replace the Battery in a Hyundai Elantra Key?
2 Answers
The battery type for the Elantra: CR2032. Follow these steps to replace the battery: 1. Insert a thin tool into the slot and gently pry open the remote cover. 2. Remove the old battery and install the new one, ensuring correct battery placement. 3. Reattach the remote key cover. Additional details: 1. If you suspect the remote key is damaged or not functioning properly, consult an authorized Hyundai dealer. Improper disposal of batteries can harm the environment and human health; dispose of them according to local laws and regulations. 2. Each vehicle can register up to 2 smart keys. If a smart key is lost, immediately take the vehicle and remaining keys to an authorized Hyundai dealer. Towing may be required if necessary. 3. If a smart key is placed too close to a mobile phone, the phone's normal operation signals may interfere with the key's signals, especially during calls, texting, or sending/receiving emails. Avoid storing the smart key and mobile phone in the same pocket or jacket; maintain sufficient distance between the two devices.
I've been driving a Hyundai Elantra for several years, and changing the key fob battery is quite simple. First, use a small flathead screwdriver to remove the tiny screw on the back of the key. If there's no screw, just pry open the casing with your fingernail or a plastic pry tool—avoid using metal to prevent scratches. Once opened, you'll see the coin cell battery inside, usually a CR2032 model. Note the positive/negative orientation before removing the old battery. New batteries can be bought at supermarkets or stationery stores for about one yuan. When installing the new battery, make sure the positive side faces upward, gently press it in, then reassemble the casing and tighten the screw. After assembly, test the buttons to ensure they work. If it still doesn't function, there might be contact issues or the key might be damaged. To extend battery life, avoid dropping the key or exposing it to high temperatures—typically, the battery lasts one to two years before needing replacement.
