To replace the key battery for Mazda 3 Axela, follow these steps: 1. Press the button on the remote key and remove the mechanical key; 2. Use a tool to pry open the back cover along the middle seam of the key; 3. Remove the old battery and replace it. The Mazda 3 Axela is a compact car with body dimensions of 4662mm in length, 1797mm in width, 1445mm in height, and a wheelbase of 2726mm.

Changing the key battery for the Mazda Axela is actually quite easy. I've done it myself several times and find it to be a money-saving trick. When you notice the remote control distance shortening or the key light not illuminating, it's time to take action. First, remove the mechanical part of the key from the bottom of the handle where there's a small notch—press gently with your finger or a flat tool to pop it out. Then, use your fingernail or a thin tool to carefully pry open the key shell along the middle seam, being cautious not to apply too much force to avoid scratching the plastic. Inside, you'll find a round coin cell battery, typically a CR1620 model. Pay attention to the positive and negative orientation; after removing the old battery, place the new one in the correct position. Close the shell and press it firmly, then reinsert the mechanical key and test if the lock button lights up. The whole process takes just a few minutes. Buying batteries online costs only a few yuan each, and they usually last one to two years, making DIY replacement much cheaper than going to a 4S shop. Also, avoid exposing the key to moisture or high temperatures when storing it.
