Why Does Your Key Fob Need a New Battery?

Key fobs are small but mighty devices that make life easier by locking and unlocking your car doors with the push of a button. However, like any electronic device, the battery inside your key fob has a limited lifespan. When the battery starts running low, you may notice that the signal weakens, or the buttons don’t work as reliably as they used to. Replacing the battery will bring your key fob back to life and ensure it’s functioning at its best.

Tools You’ll Need to Change the Battery

Before diving into the process, make sure you have the following tools:

• Replacement battery: Typically, key fobs use small button batteries like CR2025 or CR2032. You can find the specific battery type in your car’s manual or by checking the markings on your current battery.
• Small screwdriver: A flat-head or Phillips screwdriver will be required to open the key fob.
• Plastic pry tool (optional): If you want to avoid scratching or damaging your key fob, a plastic pry tool can help.

How to change battery in Key Fob – Step-by-Step Guide

Step 1: Check the Key Fob’s Battery Type First, check which type of battery your key fob uses. Most car key fobs use a CR2032 or CR2025 coin cell battery, but it’s always good to confirm by looking at the old battery or referring to your owner’s manual.

Step 2:  Open the Key Fob

Locate the seam: Look for the seam running along the middle of the key fob. This is where the two halves of the fob are joined together.

Use a small screwdriver or pry tool: Gently insert the tool into the seam and pry it open. Be careful not to apply too much force to avoid damaging the casing.

Step 3: Remove the Old Battery Once the key fob is open, you’ll be able to see the old battery. Simply pop it out using your fingers or a plastic tool. Pay attention to how the battery is positioned, as you’ll need to insert the new one in the same way (positive or negative side facing up).

Step 4: Insert the New Battery

Take your replacement battery and insert it into the battery compartment. Make sure the positive (+) side is facing the correct direction, as indicated by the markings inside the fob.

Press the battery gently into place to ensure it’s secure.

Step 5: Close the Key Fob

Align the two halves of the key fob and press them together. You should hear or feel a small click, signaling that the fob is closed securely.

If necessary, use a small screwdriver to tighten any screws that may be holding the fob together.

Step 6: Test the Key Fob After you’ve replaced the battery and closed the fob, test it to make sure it’s working. Stand near your car and try pressing the buttons. If everything is working properly, your key fob should unlock, lock, and start the car as usual.

Tips for Maintaining Your Key Fob

• Keep it clean: Dust and debris can get into your key fob over time, so make sure to clean the exterior with a soft cloth regularly.
• Replace the battery before it dies: If you notice your key fob working intermittently, it’s a good idea to replace the battery sooner rather than later. A dead key fob battery could leave you stranded if it fails at the wrong time.
• Avoid dropping the fob: While key fobs are designed to be durable, dropping them onto hard surfaces can damage both the battery and the internal components.
