Understanding Car Key Batteries
Car key batteries are small, but they play a crucial role in the functioning of your car key. The battery is responsible for powering the key’s electronic components, such as the transponder chip and the LED lights. There are two types of car key batteries: alkaline and lithium-ion. Alkaline batteries are more common and are used in older car keys, while lithium-ion batteries are used in newer car keys and are more energy-efficient.
The lifespan of a car key battery depends on various factors, including usage, environment, and quality of the battery. On average, a car key battery can last for 1-3 years, depending on the type and quality of the battery. However, if you notice that your car key is not working properly or is not responding to the remote, it may be time to replace the battery.
