Emergency key

A metal key used to open the car if the remote unlocking doesn't work.

An emergency key is a backup key used to access a vehicle in situations where the main key is lost, damaged, or unavailable. It typically serves as a fail-safe in case the primary key or fob isn’t working. Emergency keys are often designed to give the user basic access to the vehicle's door locks and sometimes the ignition.

In the context of modern vehicles, an emergency key can be a physical key that’s hidden inside a key fob. These fobs often contain smart technology for keyless entry and starting, but in case of a battery failure or other issues with the fob, the hidden emergency key can still open the doors or trunk. Some emergency keys can also be used to start the engine, but this usually depends on the vehicle's design and security system.

If a vehicle has an immobilizer system or other advanced security features, an emergency key might not be able to start the car as it is a often a plain metal key with no remote or transponder chip. In those cases, an auto locksmith would need to assist in programming a new electronic key to work with the car's security system, in order to de- activate the immobiliser and alarm and get the car started.

Emergency keys are a helpful tool for anyone who might find themselves locked out or in a situation where their main key isn’t working, but they might not always be sufficient to start the car if it requires more complex key programming or syncing with the vehicle’s electronics.
