Mazda car remotes are convenient devices that allow drivers to easily lock, unlock, and even start their vehicles without having to use a physical key. However, like any battery-powered device, they require occasional battery replacement. In this article, we will go over how to replace the battery in your Mazda car remote and what to do if it’s not working properly even after replacing the battery.

  1. Replacing the Battery if your mazda remote start not working.
  2. Determine the Correct Battery Type

Before replacing the battery, you need to determine the correct battery type for your Mazda car remote. This information can usually be found in the owner’s manual or by contacting a Mazda dealership.

Open the Remote

Most Mazda car remotes have a small button on the back that releases the key blade. Press this button and slide the key blade out.

Remove the Battery

Using a small screwdriver or similar tool, gently pry the remote apart at the seam. Once the remote is open, you should be able to see the battery. Carefully remove the battery and dispose of it properly.

Insert the New Battery

Take the new battery and insert it into the remote. Make sure the positive (+) and negative (-) sides are facing the correct direction, as indicated by the markings inside the remote.

Reassemble the Remote

Once the new battery is in place, snap the remote back together. Make sure all of the buttons are functioning properly before using the remote.

Troubleshooting a Mazda Car Remote

If your Mazda car remote is not working properly, even after replacing the battery, there are a few things you can try before seeking professional help.

Resync the Remote: Sometimes, a remote can lose synchronization with the vehicle’s system, causing it to stop working. To resync the remote, press and hold the lock and unlock buttons simultaneously for at least four seconds. If this does not work, consult your owner’s manual or contact a Mazda dealership for further assistance.

Check for Interference: Similar to other car remotes, interference from other electronic devices or tall buildings can cause issues with your Mazda car remote. Try moving to a different location or shielding the remote with your body to see if the issue resolves.

Replace the Remote: If none of the above steps work, you may need to replace the remote entirely. Contact a Mazda dealership to order a replacement remote and have it programmed to your vehicle.


Replacing the battery in your Mazda car remote is a simple process, but it’s important to ensure that you’re using the correct battery type and inserting it properly. If your remote is not working correctly even after replacing the battery, try resyncing the remote, checking for interference, or replacing the remote entirely. By following these steps, you can save time and money while ensuring that your Mazda car remote works correctly.
