How to Replace the Key Battery for Mazda6?
2 Answers
Steps to replace the key battery for Mazda6: 1. First open the key head and separate the key; 2. After separation, use a screwdriver to pry open both sides of the rear half, then you can see the battery; 3. Remove the old battery and install the new one; 4. After replacement, reassemble in the original order. The Mazda6 is a mid-to-high-end sedan with dimensions of 4670mm in length, 1780mm in width, and 1435mm in height, and a wheelbase of 2675mm. The Mazda6 features front-wheel drive, with a high-mounted double-wishbone independent front suspension and an E-type multi-link rear suspension.
I've been driving a Mazda 6 for five years and have replaced the key battery several times. It's quite simple. There's a small notch on the back of the key casing. Use a thin plastic piece or a coin to gently pry it open, but don't use too much force to avoid scratching the plastic. Once pried open, the cover will pop off, revealing a small coin cell battery inside, model CR2032, which can be bought for a few dollars at supermarkets or online. Remove the old battery, insert the new one with the positive side facing up (the side with the plus sign), and it's easy to get it right. Press the cover back on firmly until you hear a click to seal it tight, then quickly test the remote lock and unlock functions to confirm it's working. Always keep spare batteries handy, as they need replacement every year and a half or so when the power runs low—don't wait until it's completely dead. The first time I replaced it, I was in a hurry and didn't close the cover tightly, causing it to malfunction. After reassembling it properly, it worked fine. Now I'm more careful every time.
