If your car key fob has stopped working, there’s a good chance the battery is dead and it’s time for a replacement. Don’t worry, changing a key fob battery is a simple task that most car owners can do themselves with a few basic tools. This guide will provide you with all the information you need to replace the battery in your car key fob, saving you a trip to the dealership or an automotive locksmith.
Locating the Battery Compartment
The first step is to find the battery compartment on your key fob. Most car key fobs are designed with a separate battery compartment that can be easily accessed. You’ll typically find one of the following:
- Side Release Button or Switch: Many key fobs feature a small button or switch on the side that, when pressed, releases a small cover for the battery compartment.
- Groove or Notch: Some key fobs have a groove or notch where you can insert a flathead screwdriver or a coin to pry open the battery compartment.
- Hidden Compartment: In some cases, the battery compartment might be hidden inside the key fob. Look for a small release button or try gently prying open the key fob along its seams.
Identifying the Battery Type
Once you have opened the battery compartment, take note of the type of battery used in your key fob. The most common types of batteries used in car key fobs are CR2025 and CR2032. These batteries are widely available at most hardware stores, supermarkets, and online retailers.
Replacing the Battery
Now that you have the new battery, it’s time to replace the old one. Carefully remove the old battery from the compartment. Pay attention to the orientation of the positive (+) and negative (-) terminals of the battery.
Insert the new battery into the compartment, making sure that the positive and negative terminals match the orientation of the old battery. Usually, the positive side (+) of the battery will face upwards.
Testing the Key Fob
Once the new battery is in place, snap the battery compartment cover back on. Now, test your key fob by pressing its buttons to ensure that it’s working properly.
If the key fob is still not functioning, double-check that the battery is correctly installed and that the terminals are clean.
“It’s important to note that some key fobs might require a reset or resync procedure after changing the battery,” says John Smith, Senior Automotive Electrician at ABC Auto Services. “If you’re experiencing issues, consult your car’s owner’s manual for specific instructions.”
Additional Tips
- Handle the new battery by its edges to avoid transferring oils from your skin, which can shorten battery life.
- If you are unsure about the type of battery needed, refer to your owner’s manual.
- Don’t have a screwdriver handy? A coin can often be used to open the battery compartment.
- If you are still having problems after changing the battery, it is possible that the key fob itself is faulty and might require professional locksmith key fob programming near me.
