How to Open and Replace the Battery in a Mazda Car Key?
2 Answers
To open and replace the battery in a Mazda car key, follow these steps: 1. First, open the key head; 2. Inside the key slot, there is a black square. Find a suitable tool and apply slight pressure to that point; 3. While pressing, pull apart the upper part of the key to separate it; 4. Once separated, remove the old battery and insert the new one. Mazda's lineup includes models such as the Atenza, Mazda6, Mazda6, Ruiyi, and CX-4. Taking the 2020 Atenza as an example, it is a mid-size car with dimensions of 4870mm in length, 1840mm in width, and 1445mm in height, a wheelbase of 2830mm, a fuel tank capacity of 56.2 liters, and a curb weight of 1518kg.
I've replaced the Mazda key fob battery several times, and the process is actually quite simple. First, locate a small groove or seam on the side of the key, then gently pry open the casing using your fingernail or a thin card. Avoid using excessive force - Mazda key casings use snap-fit designs that can break easily. Once separated, you'll see the silver coin cell battery inside, typically a CR2025 model. Use a toothpick or plastic tool to remove the old battery, paying attention to the polarity markings. When inserting the new battery, place it with the printed side facing upward and press gently until it clicks into place. Finally, align the casing halves and press firmly until you hear a snapping sound. The whole process takes about five minutes, but remember to buy the correct battery type in advance - different Mazda model years may use different battery types, so it's best to check the manual before disassembly.
