4 Answers
Here is the method to replace the battery in an Axela key: 1. There is a small switch on the back of the key. Press the switch and pull out the metal key inserted inside the key while holding the top; 2. Use a flat object to pry open the gap on the side of the key, open the key cover, and you will see a small black cover inside, which is used for waterproofing. Remove it to see the battery inside; 3. Remove the old battery and insert a new one with the plus side facing up to successfully replace the battery. Additional information: The Axela has a length, width, and height of 4582mm, 1795mm, and 1458mm respectively, with a wheelbase of 2700mm. The Axela is front-wheel drive, with a MacPherson independent front suspension and a multi-link fully independent rear suspension, equipped with the SKYACTIV CHASSIS system.
I just replaced the battery for my friend's Mazda 3 (Axela) key, and the process was super simple. You'll need to prepare a new battery, usually a CR2025 model, which can be bought for a few bucks at supermarkets or online stores. Use a small tool like a flathead screwdriver or a card to gently pry open the seam on the back of the key—be careful not to damage the plastic casing with too much force. Once opened, you'll see the old battery; remove it with your fingers or tweezers, being careful not to dirty the metal contacts, as this could cause poor contact. Then, insert the new battery, making sure the positive and negative sides match the markings (usually the lettering faces up). Close the cover and press it firmly to ensure it locks in place. Finally, test the key buttons to see if the small light turns on—that's it! I've done this a few times myself—it saves money and time while teaching you a handy little skill. If you're still unsure, check the owner's manual or video tutorials for extra reassurance.
As an average car owner who has replaced the Mazda 3 key fob battery, I found the process straightforward from scratch. First, purchase the correct battery model CR2025 to avoid size mismatch. Use household small screwdrivers or coins as tools, gently pry along the key seam without brute force to prevent cracking. After removing the old battery, inspect the contacts—clean them if dusty. Ensure the new battery is installed with the positive side facing up. Snap the casing back securely and immediately test the unlock button. The entire process takes about 15 minutes; checking the battery expiry date during replacement helps avoid frequent changes. If issues arise, consult car-savvy friends instead of random tinkering to prevent circuit damage and boost confidence.
When replacing the key battery, pay attention to details to prevent accidental damage. First, operate with the key in the off state, gently pry the edge to remove the old CR2025 battery. Never use excessive force or wet hands to avoid short circuits. When installing the new battery, check that the positive and negative poles are aligned. After closing the cover, immediately test the remote lock button to ensure normal response. If the light does not come on, the contacts may be dirty—clean them or reinstall the battery. Otherwise, consult a professional repairman promptly to avoid failure while driving. Safety first—DIY is convenient but don’t push yourself too hard.
