Is your car key fob starting to act up? Do you have to press the buttons multiple times to lock or unlock your doors? It might be a sign that your key fob battery is dying and needs a replacement. Before you rush to a dealership or auto repair shop, you should know that replacing your key fob battery is a simple task you can easily do yourself. And the first question you might have is: Where To Buy Key Fob Battery? This guide will walk you through everything you need to know about finding the right battery and replacing it yourself, saving you time and money.
Why Replace Your Key Fob Battery Yourself?
While it’s convenient to have a professional replace your key fob battery, doing it yourself offers several advantages. Firstly, it’s significantly cheaper. Dealerships and repair shops often charge a premium for a service that takes only a few minutes. Secondly, it’s faster. You can replace the battery in the comfort of your own home or garage, without scheduling an appointment or waiting in line. Lastly, it’s empowering. Knowing you can handle this simple car maintenance task boosts your confidence and self-reliance.
Tools You’ll Need for Key Fob Battery Replacement
Replacing your key fob battery is straightforward and requires minimal tools. Here’s what you’ll typically need:
- A thin blade or prying tool: A watch knife or a small flathead screwdriver works perfectly for gently opening the key fob case.
- A new key fob battery: These are usually coin cell batteries, most commonly CR2032, but check your key fob for the specific type. You can often find the battery type embossed on the back of the fob or inside the battery compartment.
- A precision screwdriver (possibly): Some key fobs have tiny screws holding them together, requiring a small Phillips head screwdriver (around 1.4mm to 2.4mm).
- Tweezers (optional): Tweezers can be helpful for handling the small battery, especially in tight spaces.
- Your smartphone: Taking photos during the process, especially after opening the fob, is a smart move for reference during reassembly.
Step-by-Step Guide to Replacing Your Key Fob Battery
With your tools gathered and your new battery ready, follow these simple steps to replace your key fob battery:
-
Identify Your Battery Type: Before you even open your key fob, check for markings indicating the battery type. Look for embossed letters and numbers on the back of the fob or inside the key sleeve. Common types include CR2032, CR2025, and CR1632. Knowing the correct battery beforehand ensures you purchase the right replacement.
-
Open the Key Fob Case: Carefully inspect your key fob case. Some have screws that need to be removed first. If there are no screws, look for a small notch or seam line around the edge of the fob. This is where you’ll insert your prying tool. Gently wedge your thin blade or screwdriver into the notch and twist or pry carefully to separate the two halves of the case. Work your tool around the seam, gently popping open the fasteners one by one. Avoid forcing it open from just one point, as this could damage the case.
-
Remove the Old Battery: Once the case is open, take a picture with your phone to remember the orientation of the battery and other components. This is crucial for correct reassembly. Carefully remove the old battery. Some fobs have a small clip or sliding mechanism holding the battery in place. Use tweezers or your fingertip to gently lift the battery out.
-
Insert the New Battery: Take your new key fob battery and install it in the same orientation as the old one. Usually, the positive (+) side faces up, but your photo will confirm this. Ensure the battery is securely seated in its compartment.
-
Reassemble the Key Fob: Carefully snap the two halves of the key fob case back together. Press firmly until you hear or feel them click into place, ensuring a secure closure. If there were screws, re-insert and tighten them gently.
-
Test Your Key Fob: Once reassembled, test your key fob to ensure it’s working correctly. Press the lock, unlock, and other buttons to verify they are functioning as expected.
