2 Answers
Insert a small screwdriver into the side slot near the key blade. Carefully push the screwdriver towards the key blade in the direction indicated by the arrow to separate the key blade from the chip case. Insert a flat-head screwdriver into the groove on the side of the chip case and rotate it to release the shell clips in this area. Then insert the flat-head screwdriver into the groove at the top of the chip case and rotate it to release the shell clips there, allowing the chip case to be separated. On the left is the CR2032 battery, and on the right is the chip circuit board. Install them according to their corresponding positions in the shell.
Replacing the key fob shell. I often fix small things myself and find it quite simple. First, prepare the tools: purchase a new key fob shell that matches your car model (usually available online), along with a small screwdriver or pry tool. Next, carefully examine the structure of the old key fob shell—most are secured with small screws, while some have snap-on designs. Gently pry or unscrew it open, avoiding excessive force to prevent scratching internal components. When removing the battery and electronic chip module, be mindful of the battery’s position to prevent it from falling out, and consider taking a photo to document the original setup. Place the removed parts into the new shell, ensuring proper alignment to avoid reversing them, then close the new shell by pressing gently or tightening the screws. Finally, test the key to confirm it locks/unlocks the doors normally—success! The whole process takes about 10 minutes, but details vary by car model; searching for a tutorial specific to your model online can be a big help. Replacing a worn or damaged old shell extends the key’s lifespan and saves money. With tools ready and gentle handling, don’t fear mistakes.
