The solution for a malfunctioning car remote key is to replace the battery. The replacement method is as follows: 1. Slide the safety switch on the remote key; 2. Remove the mechanical key; 3. Insert the mechanical key into the gap at the bottom to pry open the shell; 4. Use a hard card to pry out the old battery from the battery gap and replace it with a new battery of the same model; 5. Reassemble the shell and reinsert the mechanical key. The functions of the car remote key include: 1. Press and hold the lock button after turning off the engine to close the windows; 2. Press the horn button on the key to alert the owner of the vehicle's location; 3. Press and hold the trunk unlock button to automatically open the trunk.
