Remove the battery holder tray from the rear cover of the key fob

Whether you’re upgrading your battery or replacing your old one, it’s a good idea to take a look at the battery holder tray that’s hidden away under the rear cover of your Mazda cx-5 key fob battery. This compartment contains a battery and two cables that aren’t necessarily easy to get at. In fact, it’s best to consult the owner’s manual to learn the best way to remove the battery holder from the ol’ Mazda cx 5 key fob.

To get at the battery holder, you’ll need a small flathead screwdriver with a softer tip. Remove the battery holder tray by tapping the side of the case with the screwdriver. This should free up the rectangular battery holder tray. Alternatively, you can visit a local Mazda repair shop for a quick and painless upgrade.

A closer inspection of the battery holder tray should reveal a small green circuit board with metal electrical contacts on the bottom. You’ll also notice a round battery cover and two cables. These cables are the same diameter, but one cable is positive and the other is negative.

Reattach both sides of the key fob

Whether you’re a new owner or an experienced driver, replacing a Mazda CX-5 key fob battery is a quick and easy task. To begin, you’ll need a CR2025 battery, a flat-head screwdriver, and a clean space to place the key fob parts.

First, you’ll need to remove the metal key. You can do this by gently prying open the case. To open the key fob case, you’ll need a flat-head screwdriver with a taped tip. Place the screwdriver in one of the slots on the key case and press it gently. Once you’ve pryed open the case, place the key fob in a clean space and carefully insert the new battery. You’ll need to replace the rubber ring underneath the battery, too.

Once you have a new battery, you’ll need to replace the cover on the key case. Place the new battery with the positive side facing up. The key cover will need to be attached to the key case until you hear a click.

Troubleshoot any issues you may be having with your car’s key fob

Changing a key fob battery can save a lot of money. If you are not sure about handling the key fob circuit, do not touch it with your bare hands. It can be dangerous.

The most common key fob problem is that the battery is not working. A faulty battery can stop the immobilizer system from working. A weak battery can also prevent the keyless entry system from receiving a signal from the key. It can also prevent the engine from starting.

The battery may be the culprit, but other problems can also contribute to the key’s malfunction. If your key is unable to start your Mazda CX-5, you may want to consider replacing the battery. A key fob battery is marked with the voltage it holds.

Another common key fob problem is that the buttons are faulty. You may need to press the button several times before the vehicle accepts the signal. You should also check to see if the locking mechanism of the car is working properly.
