Replacing A Toyota Corolla Car Key Battery

Battery problems in car keys are annoying, but I’m here to help you. If the keyless entry remote for your Toyota Corolla needs a new battery, you can do it in a jiffy.

You’ll also need a 2016 3V button cell battery and a small flathead screwdriver (or a penny if you don’t have a screwdriver) before you can get started.

This is how you swap out the batteries in the key fob for your Toyota Corolla:

• You first need to look for a tiny notch or groove on the side of your key chain. A coin or small screwdriver can be used to pry open the key, which must be done carefully.
• Second, once you have opened your key fob, you’ll see a tiny plastic casing inside the case.
• In the third step, you’ll need to pry the battery out of its compartment by finding the little opening under the battery.
• Fourth, insert the new battery into the key with the plus (+) side up.
• Fifth, reassemble the key fob by clicking the plastic parts back.
• Keys exist for everything that matters to humans: automobiles, homes, and safes. The key to savings is a metaphorical key that many people fail to see. This is not like a standard key; it can be a coupon or even a piece of paper representing money.
