If your Mazda key fob is acting up – flashing inconsistently or failing to unlock your car doors – a dead battery is often the culprit. Luckily, changing the key fob battery is a quick and easy task you can do yourself. This guide will walk you through the process, step by step, so you can get back on the road in no time.
What You’ll Need:
- A new CR2032 battery (This is the most common battery size for Mazda key fobs, but it’s always best to double-check your owner’s manual).
- A small flat-head screwdriver
- Optional: A plastic pry tool (This can help prevent scratching your key fob).
Finding the Battery Compartment
Mazda key fobs are sleekly designed, and the battery compartment isn’t always immediately obvious. Here’s how to find it:
- Examine your key fob: Look for a small seam or groove running along the side or back of the fob. This usually indicates the battery cover.
- Locate the release: You might see a small notch or indentation along the seam. This is where you’ll insert the screwdriver or pry tool.
Opening the Key Fob
- Insert the screwdriver: Carefully wedge the tip of your flat-head screwdriver (or pry tool) into the notch or indentation.
- Gentle pressure: Apply gentle pressure and leverage the screwdriver to pry open the battery cover. Avoid using excessive force, as this could damage the fob or cover.
- Separate the halves: Once the cover pops open, carefully separate the two halves of the key fob. You’ll see the battery inside.
Replacing the Battery
- Remove the old battery: Note the orientation of the positive (+) and negative (-) sides of the battery. Carefully remove the old battery, using the screwdriver or your fingernail to lift it out if necessary.
- Insert the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side faces the same direction as the old battery.
- Reassemble the fob: Align the two halves of the key fob and press them firmly together until you hear a click, indicating the cover is securely closed.
Testing the Key Fob
Once the key fob is reassembled, test all its functions to ensure the new battery is working correctly:
- Lock and unlock: Try locking and unlocking your car doors using both the buttons on the key fob and the physical key.
- Start the engine: If your Mazda has push-button start, try starting the engine using the key fob.
Important Tips
- Handle the battery with care: Avoid touching the flat surfaces of the new battery, as this can transfer oils from your skin and potentially reduce its lifespan.
- Don’t force it: If the key fob doesn’t close easily, double-check that the battery is correctly positioned and the cover is properly aligned.
- Dispose of the old battery responsibly: Take your old battery to a designated battery recycling point.
Still Having Trouble?
If you’ve replaced the battery and are still experiencing issues with your Mazda key fob, it’s best to consult your owner’s manual or contact a certified Mazda dealership for assistance. They can diagnose the problem and provide a solution.
