How to replace the battery in a Besturn X80 car key?

Pinch the metal top part of the key with your fingers and pull out the mechanical key from it. Insert the mechanical key into the plastic slot in the key placement area to pry open the back cover of the remote key. Remove the old battery from inside the key, making sure to properly dispose of the used battery. Insert a new battery of the same model into the key, then reassemble the key by reversing the disassembly steps. Do not leave the key exposed in environments colder than 0°C or hotter than 50°C, as this will significantly reduce the battery's lifespan.
I recently replaced the battery for my Besturn X80 key, and the process was quite simple. The key usually has a snap design—just flip it over, locate the small gap, and gently pry open the cover with your finger or a small tool. Inside, you'll typically find a CR2032 coin cell battery. Be careful not to reverse the polarity; the positive side should face up. When removing the old battery, avoid using excessive force to prevent damaging the chip. For the new battery, I recommend purchasing from an auto parts store or supermarket—brands like Panasonic or Duracell work well. After closing the cover, test the remote functions. Avoid exposing the key to high temperatures, such as leaving it in a sun-exposed car, as this drains the battery faster. Proper care can extend the battery life by one to two years. DIY replacement saves a lot of money and avoids the hassle of visiting a 4S店.
