One annoying issue is that you have to go to the car and test the key fob. Usually, key fobs have a small red light that flashes whenever a button is pressed but this one does not.

Key fob battery replacement

The battery in the key fob was due for a replacement. It was very easy.

Tools needed: Small flat-head screwdriver, replacement battery.

Opening was time-consuming since I was scared of breaking the key fob.

Step 1:
Remove the key from the key fob by pressing the key release button

Step 2:
Insert a small flat-head screwdriver into the rectangular hole highlighted. Run it around the border of the key. Pry it open gently as springs (used for the release button) might fly out.

Step 3:
Now that it is open, replace the battery with a CR2032 battery, I paid 50₹ for my replacement Panasonic one. The original was by Maxwell. Positive terminal is labelled.

My replacement battery had a textured negative terminal, it isn't an issue.

Step 4:
Make sure the button used to release the key is aligned properly (it has a slight curve to it) with the other shell. Close the shells together.

One annoying issue is that you have to go and test the key fob with the car. Usually, key fobs have a small red light that flashes whenever a button is pressed but this one does not.
