1. Transponder Keys: Introduced in the mid-1990s, these keys include a plastic head containing a small computer system chip. Even if the metal is cut properly, the car will not start unless the chip is set to the car’s ignition.
2. Remote Keyless Entry (RKE) Fobs: These are handheld gadgets that permit locking and opening doors through radio waves. In lots of older designs, the fob is different from the mechanical key.
3. Key Fob and Key Combos: Often called “switchblade” secrets, these combine the remote buttons and the physical key into one folding system.
4. Smart Keys/ Proximity Keys: These represent the present peak of key innovation. They permit motorists to keep the “key” in their pocket while unlocking doors and starting the engine through a “push-to-start” button.
