Key fobs are incredibly convenient until their batteries die. Suddenly, unlocking your car becomes a manual task, and remote start is a distant memory. But don’t worry, replacing your key fob battery is usually a straightforward process you can do yourself. This guide will show you how to easily get the battery out of your key fob and get you back to enjoying those convenient features.
Step 1: Detaching the Key (If Applicable)
Many key fobs include a physical key that can be detached. This is often a crucial first step to accessing the battery compartment. Look for a button or release catch, often in a different color than the main fob body. Press this release while gently pulling on the key to remove it.
On many key fobs, like the one shown, the silver or metallic portion is often the detachable key. Removing this key may reveal screws or a seam line to open the fob.
Step 2: Opening the Key Fob Casing
With the key removed (if applicable), the next step is to open the key fob casing to access the battery. Most key fobs are designed to snap together tightly, creating a secure seal. You’ll typically need a small, flat-head screwdriver or a similar thin tool to gently pry the two halves of the fob apart.
Examine the key fob for a small notch or seam. This is usually the designated point to insert your screwdriver. Gently insert the tip of the screwdriver into this opening and carefully twist to begin separating the two halves of the fob. Work your way around the seam, gently prying as you go, until the case begins to split open.
Be patient, especially the first time you open the fob, as the latches can be quite tight. Avoid applying excessive force, which could damage the casing. Work slowly and gently until the two halves separate.
Step 3: Removing and Replacing the Battery
Once the key fob is 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 ensures you install the new battery correctly.
Most key fobs use small, circular batteries, often CR2032, CR2025, or CR1632 types. The exact type will be printed on the battery itself. You can typically find replacement batteries at drugstores, supermarkets, and auto parts stores.
Carefully remove the old battery. You might be able to gently pry it out with your fingertip or the edge of your screwdriver. Install the new battery, ensuring the correct orientation matches how the old battery was placed.
Step 4: Reassembling the Key Fob
With the new battery in place, carefully align the two halves of the key fob casing. Press them firmly together until they snap securely back into place. You should hear a click or feel them latch together.
Once reassembled, 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, and you’re all set!
