Is your car key fob starting to act up? Don’t worry, you probably just need a new battery. Knowing How To Replace Battery Key Fob yourself can save you time and money compared to a dealership visit. This simple guide will walk you through the process, making it an easy DIY task.
Step 1: Detach the Key Fob
Most key fobs include a physical key that can be detached. Locate the release button, often a small silver or differently colored part of the fob. Press and hold this button to slide out the mechanical key. This is usually straightforward and reveals the key fob casing you’ll need to open.
Once the key is removed, you’ll see the seam of the key fob casing. This is where you’ll need to gently pry it open to access the battery compartment. Look for a small notch or indicator, which often marks the best spot to start separating the two halves of the fob.
Step 2: Pry Open the Key Fob Casing
With the key detached, the next step is to carefully pry open the key fob. For this, you’ll need a small, flat-head screwdriver or a similar thin tool. Insert the tip of your screwdriver into the notch you identified earlier. Gently twist or lever the screwdriver to begin separating the two halves of the key fob.
Be patient and work your way around the seam. The casing might be tight, especially the first time you open it. Avoid applying excessive force, which could damage the fob. Once you’ve worked around the perimeter, the front and back plates should separate, revealing the battery inside.
Step 3: Replace the Key Fob Battery
With the key fob open, you’ll see the battery. Before removing the old battery, take a moment to note its orientation – specifically, which side is facing up (+ or -). This is crucial for installing the new battery correctly. Gently remove the old battery. These batteries are typically small, button-cell batteries.
Replace the old battery with a new one of the same type. Ensure the positive and negative sides are oriented correctly, matching how the old battery was placed. The correct battery type is usually printed in your car’s owner’s manual or sometimes on the inside of the key fob itself.
Step 4: Reassemble the Key Fob
Once the new battery is in place, carefully align the two halves of the key fob casing. Press them firmly together until they snap back into place. You should hear a click sound, indicating that the casing is securely closed.
After reassembly, test your key fob by pressing the lock and unlock buttons to ensure it’s working correctly. Finally, slide the manual key back into the fob until it clicks into its locked position. You’ve now successfully replaced your key fob battery and your remote should be working like new!
