The Evolution of Vehicle Access
The journey from basic serrated metal secrets to encrypted clever fobs shows the market's dedication to both benefit and security.
Mechanical Keys: Standard metal secrets used entirely for physical lock adjustment.Transponder Keys: Introduced in the 1990s, these keys contain a small chip that communicates with the car's immobilizer.Remote Keyless Entry (RKE): Separate fobs that allowed for remote locking and unlocking by means of radio frequencies.Integrated Key Fobs: Combines the mechanical key and the remote into one system.Smart Keys/Proximity Fobs: These enable "push-to-start" functionality and keyless entry without ever eliminating the device from one's pocket.Understanding the Technology
Key fob programming depends on Radio Frequency (RF) signals. Each fob includes an unique recognition code. When a button is pushed, the fob sends a signal to the vehicle's receiver.
