Last time I changed the battery for my old Mazda6 key, it was super easy. There's a small groove on the side of the key - just wedge a coin in there and twist to open it. Inside lies a button battery, model CR1620, which you can easily buy at any supermarket. When replacing, make sure not to install it upside down; the positive side should face upward! After closing the cover, remember to press the unlock button a few times to test. If the remote doesn't work, the chip might have shifted and needs to be repositioned flat. The whole process takes just three minutes, saving you 200 bucks compared to going to the 4S shop. The key has poor water resistance, so be careful not to get it wet during disassembly.

Hey, my daughter's 2008 Mazda6 just had its key fob battery replaced. First, pop out the mechanical key. There's a small slit at the back of the key fob - gently pry it open with a flathead screwdriver. The battery inside is just like a watch battery, and you can't go wrong with a Panasonic CR1620. When installing the new battery, pay attention to the polarity markings - the shiny side should face downward. After closing the case, don't rush to use it immediately. Hold down the unlock button until the red light flashes three times to confirm successful reset. The rubber gasket on older car keys tends to deteriorate, and prying too hard might break the clips. If you really can't manage it, just go to a locksmith shop at the auto parts market - the labor cost is only about 20 yuan.

The Mazda 6 keys come in folding and straight versions. For the folding type, slide out the mechanical key and use a coin to pry open the key casing. The straight version can be opened by simply popping off the shell. It's recommended to use a Panasonic CR1620 battery, available at convenience stores for about ten yuan each. When installing the battery, make sure the metal side faces down to contact the spring plate. If it doesn't work after replacement, don't panic—press all buttons ten times in sequence to re-pair. Be careful not to dislodge the internal chip during the process. Keeping a spare battery in the glove box is crucial, especially in winter when battery drain is faster.
