The battery model for the Sylphy key is a 3V CR2025 button battery. Below is related information about car keys: Method for replacing the key battery: Remove the mechanical key, use a flat-head screwdriver to pry open a small gap from the side of the key, open the key cover, use the flat-head screwdriver to remove the old battery, insert the new battery with the positive side facing down, then reassemble the circuit board and key cover. Car key: A car key is a tool used to start and stop the car. Modern car keys use a chip, which is part of a magnetic chip system. The reading coil in the car's ignition lock cylinder reads the chip in the key; each chip has fixed digital information.
I've been driving a Nissan Sylphy for six years and have replaced the key battery a few times. The standard model is a CR2033 coin cell battery, which is easily available in supermarkets or online for about 10 yuan each. The first time I replaced it, I gently pried open the key shell with a flat-head screwdriver. Inside, there's a battery slot. After removing the old battery, I placed the new CR2033 battery with the printed side facing up, then closed the shell and tested the remote function. The whole process took less than 5 minutes. I recommend checking it once a year; the battery life is usually 1-2 years. Replace it when the signal weakens to avoid being unable to lock the car midway. After replacement, the key's sensitivity is restored, and doing it yourself saves the 50 yuan fee at the 4S shop. Remember to keep spare batteries at home for emergencies.
