What is the battery specification for Mazda6's key?

Mazda6's key uses a CR1620 coin cell battery, which is a widely used battery type in vehicle keys. The Mazda6 is a mid-size sedan with a 4-door, 5-seat configuration. Its dimensions are 4670mm in length, 1780mm in width, and 1435mm in height, with a wheelbase of 2675mm. In terms of exterior design, the Mazda6 features a front bumper and chrome-plated wing-shaped grille inspired by Mazda's coupe-style design. It also incorporates independent front fog light clusters and newly designed 10-spoke alloy wheels with alternating thick and thin spokes, giving the car a more fashionable and dynamic appearance.
My Mazda6 key uses a CR2025 coin cell battery, which is that small 3-volt lithium battery. When the key battery died before, the dashboard displayed a remote control failure warning, and I couldn't even open the car door—it really gave me a scare. I looked it up online, confirmed the battery specs, and immediately bought a new one at a nearby convenience store to replace it myself. Just open the key casing, take out the old battery, and pop in the new CR2025—simple and hassle-free, costing just over ten yuan. It's important to regularly check the key signal; for example, if the indicator light dims when pressing the unlock button, it might mean the battery is running low. Replacing it early avoids trouble at critical moments. Remember to choose branded batteries—cheap no-name ones can leak and damage the key, so don't skimp and regret it later.
As a car enthusiast, I've researched that the Mazda6 key fob battery specification is CR2025. This compact battery provides sufficient capacity, and its 3-volt output perfectly matches the car's remote system. When the battery ages and voltage drops below 2.5V (measured with a multimeter), key functions become erratic - that's when replacement is needed. During replacement, avoid contaminating the contacts to prolong service life. Smart key batteries typically last 1-2 years depending on usage frequency, with high temperatures accelerating deterioration. I recommend purchasing OEM replacements from Amazon or auto shops. After installation, test all buttons to verify remote locking/starting functions. Proper maintenance of these details ensures smoother vehicle operation.
