2. Remote Key Fobs

These are systems that combine the mechanical key with a remote control for locking and unlocking doors. They typically include an “all-in-one” design where the metal blade flips out or is permanently connected to the remote real estate.

3. Smart Keys (Proximity Keys)

Smart secrets represent the existing peak of automobile entry technology. These keys do not require to be inserted into a lock. As long as the key remains in the chauffeur's pocket or bag, the vehicle recognizes the distance, permitting the doors to be opened and the engine to be started through a “push-to-start” button.
