How to Start a Civic When the Key Fob Battery Dies?

[MarcusLee]

Generally, when you pick up the car, the 4S dealership will provide two keys—one as a spare. If the commonly used key runs out of battery, you can use the spare key. Remote key fobs can usually be opened, revealing a coin cell battery inside. If the battery is dead, open the key fob to check the battery specifications, purchase a replacement, and install it. Most vehicles are equipped with a mechanical keyhole designed for situations when the remote key fob battery dies. It might be hidden, but once you locate the keyhole and use the key, you can start the car.
