Can Car Keys Run Out of Battery?

[DeChase]

Car keys can run out of battery. The battery in a car remote key typically lasts 2-3 years before being depleted, though this varies depending on the vehicle model. Signs that a remote key is running out of battery include: Shortened remote range: Initially, you could unlock the car from 5-6 meters away, but now you have to stand very close to the door for it to respond; Occasional unlocking failure: Sometimes the door won't unlock, requiring multiple button presses to succeed—these are also symptoms of a dying remote key battery; Indicator light on the key: Pay attention to the indicator light on the key. If it appears dimmer than usual or flickers when you press the button, it's time to prepare for a battery replacement or consider replacing the key itself. If the car key runs out of battery, you can use the spare mechanical key to unlock the door. Generally, cars come with two types of mechanical keys: folding or hidden. Some may be concealed inside the key fob, while others are attached to the side of the key. When the remote key battery dies, the mechanical key can still open the door. Typically, the door lock is located on the handle. Some car models hide the lock cylinder for aesthetic purposes, but it is always near the handle.
