Unlike traditional mechanical keys, programmed keys use radio frequency identification (RFID) or transponder chips to authenticate the key and start the engine. This technology significantly enhances vehicle security by making it extremely difficult for unauthorized individuals to start the car without the correct key. Programmed keys are commonly used in modern vehicles, especially those manufactured in the last two decades. They are often referred to as remote keys, key fobs, or smart keys, depending on their functionality. Some programmed keys allow you to lock and unlock your car remotely, while others can even start the engine without inserting the key into the ignition.

Valet Keys: Valet keys are a special type of programmed key that allows limited access to the vehicle. They are often used by car rental companies and valet services to provide temporary access to the car without giving away the full key. 5.
