How To Change Your Dead Car Key Batteries In 5 Simple Steps

Do you remember the good old days when car keys were just a flat piece of metal with notches etched into them?  These days, nearly every car comes with a keyless remote to lock and unlock doors. No more sticking a key into doors or the ignition. Impressive, right? These keys can be quite futuristic compared to their ancient counterparts until … you have a dead battery! Next thing, you’re stranded, and can’t get into your car! Not today! 

The case of dead car key batteries when it comes to a device or gadget is inevitable, but you don’t need to stress about it. It’s very possible to replace the battery by yourself in your key fob, and it’s easier than you think. Don’t wait until it’s too late – when the alarm won’t go off! All you need is a small, flat-tipped screwdriver and a new battery.

1. Inspect the key fob for a slot or opening

Inspect the key fob for a notch along the seam. It may not be easy to spot immediately, so this might require a bit of patience from you. 

2. Use a flat-blade screwdriver or butter knife to pry open the key fob.

Once you have located the notch to open, take your screwdriver or butter knife, insert the edge into the notch, and start prying open the key fob, carefully working your way around the seam until all the clips are released. 

Alternatively, your key fob might have a slot that fits a coin. Find a coin that closely fits the slot. Insert the coin and use it as a screwdriver to get the cover off. Other remotes use tiny screws or must be pried open. 

3. Check the battery type

Most manufacturers, like Honda, make it fairly easy to find out what kind of battery your key fob uses. The battery number should be embossed on the backside of the fob. Usually, it’s a four-digit number e.g. 2032. If you drive an older model, the battery type may not be indicated on the back of the fob. In this instance, you can check the backside of the battery for the number. 

4. Replace the old battery with a new one

The dead car key batteries should come out with ease if you pop it out with your finger. Replace the new battery where the old one was.

5. Snap back the two halves of the key fob

Now that the new battery is in place, you can reassemble the key fob. Be sure that it is tightly secured, we don’t want any parts falling out! 

Voila! In less than 5 minutes, you have replaced your key fob batteries!
