How to Replace the Battery in a Dongfeng Car Key?
2 Answers
Eject the car key and use a flathead screwdriver to pry open the cover by leveraging the gap in the middle of the key compartment. After opening the key, remove the rear section. Gently pry the gap near the back with a flathead screwdriver to reveal the remote key's chip. Remove the key chip, and you will see the battery compartment on the back. Gently push the battery out with the screwdriver. Before installing the new battery, confirm that the replacement battery's model and voltage match the original. Ensure correctness before proceeding. Reassemble the remote key in reverse order of disassembly, then test it.
I've been driving Dongfeng vehicles for almost twenty years, and changing the key battery is quite simple. First, identify the model of your key. Typically, Dongfeng car keys use CR2032 coin batteries, which can be purchased at supermarkets or online. When replacing the battery, prepare a small Phillips screwdriver and a flathead tool. There's usually a slot or screw on the back of the key. Use the screwdriver to remove the screw; if there isn't one, gently pry open the casing with the flathead tool. Once open, remove the old battery, paying attention to the polarity—the old battery usually has the side marked + and - facing up, so insert the new battery in the same orientation. After placing the new battery, reassemble the key casing, ensuring it clicks securely into place. Once assembled, test the key buttons to see if they unlock or start the car. I recommend regularly checking the battery life; if the key's sensing distance shortens, replace it promptly to avoid being unable to open the door midway. Also, choose reputable brands when buying batteries to avoid leakage from low-quality products corroding internal components. If you can't open it yourself, don't force it—take it to a repair shop or 4S store for safer assistance.
