They are more secure because the car must be within the range of a sensor to start the engine. This kind of key is also more difficult to duplicate as it is laser cut on both sides. These keys are also known as "flip keys" or "transponder key". Certain car manufacturers utilize a similar design called a Tibbe Key, which is more challenging to duplicate.

Key Fobs
Since their introduction in 1990, key fobs are now an essential feature of cars. These tiny devices are much more than an instrument to unlock doors and start the car. They also act as a major deterrent to theft. Key fobs connect with vehicles and perform a variety of functions using radio signals. When the key fob is pressed, it sends the coded signal to a receiver located near the lock system in the vehicle. The receiver reads this code and performs the desired actions, like opening doors or even starting the car. Some key fobs are capable of performing other functions like activating a panic alarm, or disarming or arming the security system.
The radio frequency (RF) signals utilized by key fobs are the same as the ones that are used by cell phones. When the key fob comes within range of a receiver it sends out a short burst that energizes the copper coils on either side of the device. The coils convert the energy from the radio into electricity, which powers a microcomputer chip inside the fob. The computer then sends a digitized version of your car's unique ID number that is then verified by the receiver.
A lot of newer cars come with remote starters which allow you to press an electronic fob to start the engine. In certain instances, you'll have to insert an actual key into the ignition lock in order to start your car. The latest fobs are also equipped with a small metal key that's designed to function in the event that the RF system fails.
