What is the battery model for Mazda 6 key?
2 Answers
Mazda 6 key battery model is 1620. Here are the specific details about the battery models used in car remote keys: CR2016 battery model: This battery is widely used in car remote keys. It has a voltage of 3V. Generally, car key batteries use 9V power supply, so all three batteries are replaced each time. 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. CR2025 battery model: Its usage rate is much lower than CR2016. It is thicker compared to 2016 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. CR2032 battery: It also has a voltage of 3V, but its capacity reaches about 200mAh, so its thickness is twice that of CR2016.
Once my Mazda6 key fob ran out of battery, which was quite a panic. I checked the manual - it takes a standard CR2032, those small silver coin batteries. Replacement is pretty straightforward: use a thin tool like a small screwdriver or coin to carefully pry open the key casing, remove the old battery, make sure to insert the new one with correct polarity (usually concave side down), and it'll light up green when properly installed. Watch for signs like unresponsive buttons or reduced remote range - that means it's time for replacement. Never use other battery types as they accelerate wear. I recommend annual checks and keeping spare batteries at home or in the car to avoid sudden failures. Compatible versions are cheap online, about 5 yuan each, and can last over two years.
