Identifying the Correct Battery Type

When it comes to changing the battery in your Mazda CX 5 key fob, the first step is to identify the correct battery type. Each key fob model may require a different type of battery, so it’s important to check the owner’s manual or do some research to determine the specific battery type needed for your key fob.

One way to identify the correct battery type is to open up the key fob and locate the existing battery. The battery type is typically printed on the battery itself, making it easy to determine the exact type of battery needed for replacement. Alternatively, you can also refer to the key fob’s user manual or look up the information online using the key fob’s model number.

Once you have identified the correct battery type, you can proceed with purchasing a replacement battery. It’s important to ensure that you are purchasing the right type of battery to avoid any issues with compatibility. Knowing the correct battery type also helps in preventing damage to the key fob and ensures that it will function properly after the battery replacement process.

Step-by-Step Battery Replacement Process

When it comes to replacing the battery in your Mazda CX 5 key fob, it’s important to follow a step-by-step process to ensure the job is done correctly and efficiently. This involves identifying the correct battery type, removing the old battery, inserting the new one, and reprogramming the key fob.

First, you will need to gather the necessary tools and materials, including a small Phillips head screwdriver and a replacement CR2025 battery. Once you have these items, you can begin the process by carefully removing the screw on the back of the key fob using the screwdriver. Next, use the screwdriver to gently pry apart the key fob shell to expose the internal battery compartment.

Inside the key fob, you’ll find the old battery, which can be easily removed by gently pressing down on it and sliding it out. After removing the old battery, insert the new CR2025 battery into the compartment with the positive side facing up. Once the new battery is in place, reassemble the key fob by snapping the two halves of the shell back together and reinserting the screw.

Testing the New Battery

Testing the New Battery

Once you have successfully replaced the battery in your Mazda CX 5 key fob, it is important to test the new battery to ensure everything is functioning properly. Testing the new battery will give you peace of mind knowing that your key fob will continue to work without any issues.

One way to test the new battery is to simply press the buttons on the key fob to see if the car responds. If the car locks and unlocks as it should, then the new battery is likely working correctly. However, if the car does not respond, you may need to double check the battery installation or consider the possibility of a faulty key fob.

Another method for testing the new battery is to use a battery tester or multimeter. This will allow you to measure the voltage of the new battery and ensure that it is within the acceptable range. If the voltage is low, it may indicate that the battery is already drained and needs to be replaced again.
