How Long Can a Car Key Last After Displaying Low Battery?
1 Answers
When a car displays a low battery warning for the key, it can typically last for a few more months. If the alarm light on the vehicle's remote key is illuminated, it is recommended to replace the remote key battery as soon as possible. Car owners can purchase a standard-brand button battery from a reputable supermarket and replace it themselves, or they can visit a local car key shop to have a professional assist with the replacement. A remote key allows for unlocking and locking the car from a distance without inserting the key into the lock cylinder. Its advantage is that, regardless of day or night, there's no need to locate the lock cylinder, enabling convenient remote locking and unlocking. The remote key emits a weak radio wave from the owner's vicinity, which is received by the car's antenna. The electronic control unit (ECU) then identifies the signal code, and the system's actuator (motor or electromagnetic coil) executes the locking or unlocking action.
