Replacing the old battery
When it comes to replacing the old battery in a Mazda 3 key fob, it’s important to gather all the necessary tools before starting the process. You will need a small flathead screwdriver, a small Phillips screwdriver, and a replacement CR2025 battery. Once you have these items ready, you can begin the process of opening the key fob to access the old battery.
Using the small flathead screwdriver, carefully insert it into the seam of the key fob and gently twist to pry the two halves apart. Be cautious not to use too much force, as this can damage the key fob casing. Once the key fob is opened, you can locate the old battery, which is typically held in place by a small metal retainer. Remove the old battery from its housing and dispose of it properly.
Next, take the replacement CR2025 battery and carefully insert it into the housing, making sure that the positive side is facing up. Once the new battery is in place, you can carefully reassemble the key fob by aligning the two halves and pressing them together until they snap into place. Finally, perform a test by pressing the buttons on the key fob to ensure that the new battery is working properly.
Testing the new battery
After successfully replacing the old battery in your Mazda 3 key fob, the next step is to test the new battery to ensure that it is functioning properly. You want to make sure that the key fob is able to communicate with your car and lock/unlock the doors as intended.
Begin by standing near your Mazda 3 and pressing the buttons on the key fob. If the new battery is working correctly, you should be able to see the exterior lights flash and hear the doors lock and unlock as you press the buttons. If the key fob is not responding as expected, it may be an indication that the battery was not properly installed or that there is an issue with the key fob itself.
If you are experiencing any problems with the key fob after replacing the battery, it may be necessary to seek assistance from a professional or contact your Mazda dealership for further troubleshooting and potential repairs.
Reassembling the key fob
Once you have completed replacing the old battery in your Mazda 3 key fob, it is important to ensure that you reassemble the fob correctly to avoid any issues with functionality. Start by carefully placing the battery back into its slot, making sure that it is inserted in the correct position and orientation. This is important as the battery needs to make proper contact with the electrical components inside the fob.
Next, take the back cover of the fob and carefully align it with the front cover, ensuring that all the buttons and the key ring loop are properly aligned. Gently press the two halves of the fob together, making sure that they snap securely into place. Be cautious not to force the fob closed, as this could damage the internal components and the seal of the fob.
Finally, once the fob is securely closed, give it a quick test to ensure that all the buttons are functioning properly and that the new battery is providing power to the fob. If everything is in working order, you have successfully reassembled the key fob and can now use it with confidence.
