Knowing how to put battery in key fob is a surprisingly common need. Whether your car key has stopped working or you’re just noticing a weaker signal, a dead battery is often the culprit. This guide will walk you through the process of replacing your key fob battery quickly and easily, saving you a trip to the dealership and keeping you on the road.
Identifying Your Key Fob Type
Before you begin, it’s essential to identify the type of key fob you have. Different makes and models use various designs, and knowing your fob type will help you locate the correct replacement battery and understand the specific steps for opening your key fob. Some fobs have a visible screw, while others have a small release latch or require a specific tool. Consult your car’s owner’s manual or search online for instructions related to your specific car model. Understanding this beforehand will prevent unnecessary frustration and potential damage to your key fob.
Replacing the battery in your key fob yourself can save you time and money compared to going to a dealer or locksmith. Most key fobs use common batteries that are readily available at electronics stores, pharmacies, and online.

Gathering Your Supplies
Once you’ve identified your key fob type, gather the necessary supplies. This typically includes:
- The correct replacement battery: Check your owner’s manual or search online for the specific battery type required for your key fob.
- A small flathead screwdriver or similar tool: This will help you pry open the key fob casing without damaging it. Some key fobs have a dedicated slot for this purpose.
- A small container or tray: This is helpful to keep the small parts organized and prevent them from getting lost.
- Optional: A magnifying glass: If you have difficulty seeing small components, a magnifying glass can be beneficial.
Step-by-Step Instructions: How To Put Battery in Key Fob
Here’s a general guide on how to put a battery in a key fob. Remember, the specific steps may vary depending on the make and model of your car.
- Locate the release latch or screw: Carefully examine your key fob. Look for a small release latch, a screw, or a seam where the two halves of the fob connect.
- Open the key fob: If your key fob has a screw, use a small screwdriver to remove it. If it has a release latch, gently press it with your fingernail or a flathead screwdriver to separate the two halves of the fob. For fobs with a seam, carefully insert the flathead screwdriver into the seam and gently twist to pry open the casing.
- Identify and remove the old battery: Once the key fob is open, locate the old battery. Note its orientation (positive and negative sides) before removing it. Gently pry the old battery out using your screwdriver or fingernail.
- Insert the new battery: Place the new battery in the compartment, ensuring it’s oriented correctly, matching the position of the old battery. Press it firmly into place.
- Reassemble the key fob: Align the two halves of the key fob and press them together until they snap shut. If your key fob has a screw, replace it and tighten it securely.
- Test the key fob: Try locking and unlocking your car doors to ensure the new battery is working correctly.
