Is your car key fob acting up? Finding yourself pressing the unlock button multiple times before your car responds? It might be a simple fix: a key fob battery replacement. Like any battery, the one in your key fob wears out over time. You’re likely wondering Where To Replace A Key Fob Battery. The good news is you have options, ranging from a quick DIY fix to professional services.
Replacing Your Key Fob Battery Yourself: A Step-by-Step Guide
For many car owners, replacing a key fob battery is a straightforward task you can handle at home. It’s often easier than changing your car’s main battery and can save you time and money. With a few basic tools and a replacement battery, you can restore your key fob’s functionality in minutes.
Tools You’ll Need for DIY Key Fob Battery Replacement
Before you start, gather these simple tools:
- Thin Blade or Watch Knife: For carefully prying open the key fob casing.
- Replacement Battery: Typically a CR2032 coin cell battery, widely available at most retail stores.
- Precision Screwdriver: A small screwdriver (around 1.4mm to 2.4mm) may be needed depending on your fob’s design.
- Tweezers: To help you handle and position the small battery.
- Smartphone (Optional): For taking reference photos during disassembly.
Easy Steps to Install a New Key Fob Battery
Follow these steps to replace your key fob battery:
-
Pry Open the Fob Casing: Gently use your thin blade or watch knife to pry open the plastic case of your key fob. Look for a small notch or seam to begin prying.
-
Remove the Old Battery: Once open, carefully remove the old battery. Note its orientation (positive side up or down).
-
Insert the New Battery: Place the new battery in the same orientation as the old one.
-
Snap the Case Shut: Carefully snap the key fob case back together until it’s securely closed.
Knowing Your Key Fob Battery Size
Before you take apart your key fob, it’s wise to check for the battery size it requires. Sometimes, the battery size is embossed on the back of the fob or inside the key sleeve.
While many car key fobs use the standard CR2032 coin cell battery, variations exist depending on your car’s year, make, and model. For example, some models might use a CR1250 battery or require two batteries, like certain Ford Mustang key fobs.
To avoid purchasing the wrong battery, especially after disassembling your fob, double-check your car’s manual or, if possible, open the fob casing carefully to identify the battery type before buying a replacement.
Pry Gently to Avoid Damage
When opening your key fob, apply gentle pressure. Avoid forcing it open from one point, which can damage the case or internal components. Instead, use your pry tool to work around the seam of the case, gently separating the fasteners, similar to peeling an orange.
The Importance of a Reference Photo
Car key fob interiors can vary significantly, even within the same car model range. Taking a photo of the internal layout before removing the old battery is a crucial step. This photo serves as a valuable reference, ensuring you reassemble everything correctly. It also clearly shows the battery’s orientation, preventing incorrect installation.
Handle Internal Components with Care
Inside the key fob, you’ll find delicate wiring and a circuit board. Avoid touching or disturbing these components. Focus solely on removing and replacing the battery. Use tweezers or a precision tool to lift the battery out of its housing. Some fobs have small clips or sliding mechanisms securing the battery; carefully move these aside without forcing anything. Disturbing the internal circuitry could lead to needing a complete key fob replacement and reprogramming.
