Mazda 6 car key uses a 1620 button battery. The replacement method is: 1. Open the key head to find the separation slot in the folding key; 2. Press the clip inside to separate the key; 3. Use a screwdriver to pry open both sides of the back half to replace the battery; 4. Reassemble in the original order. The Mazda 6 body dimensions are: length 4670mm, width 1780mm, height 1435mm, with a wheelbase of 2675mm. The Mazda 6 is equipped with a 2.0L naturally aspirated engine, with a maximum power of 108 kW and a maximum torque of 183 Nm, paired with a 6-speed manual transmission.
Last time my Mazda6 car key had an issue—the buttons weren’t responsive, and the light was dim, so I knew it was time to replace the battery. The common model is the CR2032 coin cell battery, which is readily available at supermarkets or online and quite affordable. I’ve changed it once myself, and the method is simple: use a small screwdriver or coin to pry open the key casing from the side, where you’ll find a small round battery slot. Just remove the old battery and replace it with a new one. Press the casing firmly back together, then test the remote and door lock functions—it’ll instantly work again. These batteries typically last one to two years, so it’s wise to keep a spare handy to avoid last-minute hassles. During routine maintenance, check the battery as a quick step—it saves money and effort. Just be sure not to use the wrong battery model; checking the manual is the safest bet.
I'm a hands-on person, and changing the Mazda6 key battery is a piece of cake. Usually, it uses a CR2032 battery, which costs just a few bucks. To open the key fob, gently pry it with a coin. Once opened, you'll see a small metal slot—remove the old battery and replace it with a new one, being careful not to damage the contacts. After reassembling, test the unlock button; if the light works, you're good to go. The whole process takes no more than a minute. I recommend opting for reputable brands like Panasonic or Sony to avoid leakage issues with cheaper ones. Before the battery dies, the signal will weaken, so replace it early to save hassle. I've also checked similar models—the key is matching the right battery type. If unsure, just ask the sales staff at the store. Keep a spare battery in the car, and a practical tip: keep the key dry and avoid water contact.
