A malfunctioning key fob can be a real pain, especially when you’re in a hurry. If you’re experiencing issues with your car remote, like decreased range or unresponsive buttons, a dead 2450 key fob battery might be the culprit. Don’t worry, replacing it is usually a quick and easy fix.
Identifying Your 2450 Key Fob Battery
Most car key fobs use small, coin-shaped batteries, and the 2450 is a common type. It’s named 2450 based on its dimensions: 24mm in diameter and 5.0mm in height.
Not sure if your key fob uses a 2450 battery? Here are a few ways to find out:
- Check your owner’s manual: Your car’s manual will usually specify the type of battery your key fob uses.
- Look for markings on the battery itself: If you can access the battery compartment, the battery itself will have its type printed on it.
- Search online: A quick search for your car make and model along with “key fob battery” should yield results.
Replacing Your 2450 Key Fob Battery
Replacing a 2450 key fob battery is often a straightforward process. You’ll need:
- A replacement 2450 battery: You can find these at most hardware stores, auto parts stores, and online retailers.

Steps:
- Locate the battery compartment: This is usually on the back or side of your key fob.
- Open the compartment: Use your screwdriver or tool to carefully pry open the compartment.
- Remove the old battery: Note the orientation of the battery, as the positive (+) side should usually face up.
- Insert the new battery: Make sure the positive (+) side faces the correct direction.
- Close the compartment: Snap the compartment back together.
Troubleshooting
If you’ve replaced the battery and your key fob is still not working, there could be other issues:
- Check the battery orientation: Make sure the new battery is inserted correctly with the positive (+) and negative (-) sides in the right place.
- Clean the battery contacts: Over time, the contacts inside the battery compartment can become corroded. Use a cotton swab and rubbing alcohol to clean them.
- Try reprogramming the key fob: Your car’s owner’s manual will usually have instructions on how to do this.
“Sometimes, the issue isn’t the battery itself, but rather the programming,” says automotive electrician John Miller. “If a simple battery replacement doesn’t do the trick, reprogramming the key fob to the car is usually the next step.”
Extending the Life of Your Key Fob Battery
Here are a few tips to help prolong the life of your key fob battery:
- Avoid frequent button presses: Only press the buttons when necessary.
- Keep your key fob away from extreme temperatures: Heat and cold can shorten battery life.
- Don’t let the battery drain completely: Replace it as soon as you notice a decrease in range.
