2. Remote Key Fobs
These are systems that integrate 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 housing.
3. Smart Keys (Proximity Keys)
Smart keys represent the existing peak of vehicle entry technology. These keys do not need to be placed into a lock. As long as the key remains in the motorist's pocket or purse, the car recognizes the proximity, enabling the doors to be unlocked and the engine to be started by means of a "push-to-start" button.
Where to Get a Replacement: Weighing the Options
