Presented in the mid-1990s, these keys include a little electronic chip embedded in the plastic head of the key. When the key is inserted into the ignition, the car's computer sends an electronic signal to the chip. The car will just start if the chip sends out the appropriate reaction.
2. Remote Key Fobs
These are units that integrate the mechanical key with a push-button control for locking and unlocking doors. They often consist of an "all-in-one" style where the metal blade turns out or is permanently attached to the remote housing.

Smart keys represent the present peak of vehicle entry technology. These keys do not need to be placed into a lock. As long as the key is in the motorist's pocket or purse, the automobile acknowledges the proximity, enabling the doors to be opened and the engine to be begun via a "push-to-start" button.
