This guide will walk you through everything you need to know about changing the battery in your Mazda key fob, so you can get back on the road in no time.
What You’ll Need
Before you get started, gather the following items:
- A new CR2032 battery: This is the most common type of battery used in Mazda key fobs.
- A small flat-head screwdriver or a plastic pry tool: This will help you open the key fob.
- Your Mazda owner’s manual: This will provide specific instructions for your particular model.
Steps for Changing the Battery
Follow these simple steps to replace the battery in your Mazda key fob:
- Locate the release button or notch on your key fob. This is usually located on the back or side of the fob.
- Use the screwdriver or pry tool to gently pry open the key fob. Be careful not to damage the casing.
- Identify the old battery. It will be a small, round, silver battery.
- Carefully remove the old battery. You may need to use the screwdriver or pry tool to gently lift it out.
- Insert the new battery, ensuring the positive (+) side is facing up. Most key fobs will have markings indicating the correct orientation.
- Align the two halves of the key fob and press them firmly together until you hear a click. This indicates the fob is securely closed.
