Introduction

Vehicle keys are the physical devices used to lock, unlock, and start a vehicle. The type of key used in a vehicle can vary depending on the make and model of the vehicle. Here are some common types of keys used in vehicles:

1. Traditional key: This is a physical key that is inserted into the vehicle’s ignition to start the engine. It also can be used to lock and unlock the doors and trunk.
2. Key fob: A key fob is an electronic device that communicates with the vehicle’s onboard computer to perform tasks such as locking and unlocking doors, opening the trunk, and starting the engine. Some key fobs also have remote start capabilities.
3. Smart key: A smart key is a type of key fob that can be used to start the engine without inserting it into the ignition. Instead, the key communicates with the vehicle’s computer via radio waves. Smart keys typically have push-button start capabilities.
4. Remote keyless entry: This type of key allows the driver to lock and unlock the doors of the vehicle from a distance using a button on the key. Some remote keyless entry systems also include a panic button to sound the vehicle’s horn and flash its lights in case of an emergency.

It’s worth noting that the technology used in keys and keyless entry systems has become more sophisticated over time, with some vehicles now using biometric sensors, such as fingerprint or facial recognition, to authenticate drivers and start the engine.
