What is the battery model for Mazda 6 key?
2 Answers
The battery model for Mazda 6 key is 1620. Below are the specific details about battery models used in car remote keys: 1. CR2016 battery: This type of battery is widely used in car remote keys. It has a voltage of 3V. Generally, car key batteries use a 9V power supply, so all three batteries are replaced at the same time during each replacement. Models such as Honda, Toyota, Volkswagen, Mazda, etc., use this battery. The specifications of CR2016 are a battery diameter of 20mm and a thickness of 1.6mm. 2. CR2025 battery: Its usage rate is much lower than that of CR2016. It is thicker compared to CR2016 but has a relatively higher power storage capacity. The specifications of CR2025 are a battery diameter of 20mm and a thickness of 2.5mm. It is commonly found in audio remote controls. 3. CR2032 battery: It also has a voltage of 3V, but its capacity reaches about 200mAh, making its thickness double that of CR2016.
I've been driving a Mazda6 for several years, and the key fob uses a CR2025 battery, which is quite common. Typically, it needs replacement every one or two years. The battery drains slower in summer but may deplete faster in winter, especially with frequent use of remote unlocking. Replacing it is super easy: first, use a coin or a small tool to pry open the back cover of the key fob, remove the old battery, and insert a new CR2025, making sure not to reverse the polarity—the positive side should face up. You can buy these batteries at supermarkets or hardware stores for just a few bucks each. I always keep a spare at home to avoid getting stuck in a parking lot. Remember, a weak battery can also affect the remote's range, so test it occasionally. If the car responds slower when you press the unlock button, it's time for a replacement. DIY maintenance saves both money and hassle.
