2. Remote Key Fobs
These are units that combine the mechanical key with a push-button control for locking and opening doors. They often include an "all-in-one" style where the metal blade flips out or is permanently attached to the remote real estate.
3. Smart Keys (Proximity Keys)
Smart keys represent the present peak of automotive entry innovation. These keys do not need to be placed into a lock. As long as the key remains in the driver's pocket or handbag, the car acknowledges the proximity, allowing the doors to be unlocked and the engine to be begun via a "push-to-start" button.
