How to change a car key battery
Different car manufacturers may use different designs and technologies for their key fobs, which may result in slightly different battery replacement procedures. However, the basic steps for replacing a key fob battery are relatively consistent across most models.
Here's a step-by-step guide to help you through the process:
- The right tool for the job
The main tool you'll need is a small screwdriver, preferably one with a precision tip. This will allow you to access the internal components by removing any screws or prying open any compartments.
- Locate the battery compartment
Most key fobs have a small compartment on the back, usually secured with screws or clips. Using your screwdriver, carefully remove any screws or clips that may be holding the compartment closed. Take your time and work gently so that you don’t damage the casing or any internal components.
- Remove the old battery
You should first check the design of your fob to determine how the battery is held in place. Use your fingers or a non-metallic tool, and carefully detach it from its casing. After removing the old battery, set it aside for proper recycling or disposal.

- Insert the new battery
Before you insert a new battery, it is important to check that it is the correct type and size. Carefully put the new battery into the compartment, and make sure it fits snugly and securely.
- Close the compartment
After installing the new battery, it's time to close the compartment. Align the compartment cover with the key fob body and gently press it into place. If your key fob uses screws to secure the compartment, reinsert them and tighten them with your screwdriver. If clips are used, make sure they snap securely into place. Test the cover by giving it a gentle tug to ensure it’s firmly closed and sealed.
- Test the key fob
Before considering the job done, it's essential to test your key fob to make sure that the new battery is functioning correctly. Press the buttons on the fob to lock and unlock your car doors, and verify that the car central locking system responds as it should. If everything works correctly, you have successfully replaced your car key battery.
Which battery for my car key?
When it comes to replacing your car key battery, it's important to use the correct type to ensure compatibility and optimum performance. Most key fobs use lithium coin batteries, commonly known as Cr2032 batteries. However, it's always a good idea to check your car manual to make sure you have the correct type for your specific key fob.
