Change Key Fob Battery Easy Steps 2024

Change key fob battery is a relatively simple process that can be done at home. Here’s a step-by-step guide:

Identify the type of battery: Check your key fob to see what type of battery it uses. Most key fobs use a small coin-cell battery, such as a CR2032 or CR2025.

Your key fob likely has a small compartment or slot that contains the battery. To identify the type of battery, look for the following:

• A small circular or coin-shaped battery
• A label or marking on the battery or compartment indicating the battery type (e.g. CR2032 or CR2025)
• A “+” or “-” sign indicating the positive and negative terminals

Common types of batteries used in key fobs include:

• CR2032: A 3-volt, coin-cell battery with a diameter of 20mm and a height of 3.2mm
• CR2025: A 3-volt, coin-cell battery with a diameter of 20mm and a height of 2.5mm

Take note of the battery type and size to ensure you purchase the correct replacement.

Purchase a replacement battery: Buy a replacement battery that matches the type and size of the original.

When buying a replacement battery, make sure it matches the original in:

1. Type: Ensure the replacement battery is the same type (e.g., CR2032 or CR2025) as the original.
2. Size: Verify the replacement battery has the same diameter and height as the original.
3. Voltage: Check that the replacement battery has the same voltage rating (usually 3 volts for key fobs).

You can find replacement batteries at:

1. Electronics stores
2. Online retailers (e.g., Amazon)
3. Automotive stores
4. Hardware stores

When purchasing, double-check the packaging or product description to confirm the correct specifications.

For example, if your key fob uses a CR2032 battery, buy a replacement that says “CR2032” on the packaging, with the same 3-volt voltage rating and 20mm x 3.2mm dimensions.

Open the key fob: You’ll need to open the key fob to access the battery. This is usually done by:

• Prying open the case with a small screwdriver or coin
• Sliding the case open
• Removing screws to access the battery compartment

To open the key fob, follow these steps:

1. Prying open the case:
   • Locate a small gap or seam between the two halves of the key fob.
   • Insert a small screwdriver or coin into the gap.
   • Gently pry the case open, working your way around the edges until it comes apart.
2. Sliding the case open:
   • Check if the key fob has a sliding mechanism.
   • Locate a small button or latch that releases the slide.
   • Press the button or slide the latch to open the case.
3. Removing screws:
   • Check if the key fob has visible screws.
   • Remove the screws using a small screwdriver.
   • Gently pry the case open or lift the battery compartment cover.

Be careful not to damage the key fob’s internal components or circuitry when opening it. If you’re unsure, consult your key fob’s manual or contact a professional for assistance.

Remove the old battery: Gently pull out the old battery from the compartment.

Install the new battery: Place the new battery in the compartment, making sure it’s oriented correctly (usually with the positive side facing up).

To install the new battery:

1. Orient the new battery: Ensure the positive side (usually marked with a “+” sign) faces up.
2. Align the battery: Place the new battery in the compartment, aligning it with the contacts.
3. Insert the battery: Gently push the battery into the compartment until it’s fully seated.

• Make sure the battery is centered and not at an angle.
• Avoid touching the internal components or circuitry.

2. If you slid the case open:

   • Ensure it’s fully closed and the latch clicks into place.
