how to open key fob to replace battery
Hi Seo Changbin, I have an issue with my car's key fob. The battery seems to be dying. Can you guide me on how to open it and replace the battery?
Of course, I'd be happy to help! Don't worry, it's a simple process. First, you'll find a small notch on the side of the fob. Can you see it?
Yes, I see it. What's the next step?
Great. You'll need a flat head screwdriver or something similar, and gently insert it into the notch. Carefully wiggle it to pry open the casing. It should pop open smoothly. Please make sure to do it gently, you don't want to risk damaging it.
Alright, I've opened it. I see the battery inside. What battery type do I need to replace it with?
Most key fobs use a flat, round lithium battery type CR2032. But you should check the old battery to make sure it's the same type before buying a new one. When you have the new battery, simply put it in the same position as the old one, with the positive face up. Then, carefully put the casing back together. And voila, you've changed your key fob battery!
