These secrets integrate a physical blade (sometimes folding) with a battery-powered remote that controls door locks and alarms. The remote portion should be programmed to the car's frequency, while the blade needs to be cut to the ignition.

5. Smart Keys and Proximity Fobs

The most contemporary iteration, smart secrets enable keyless entry and push-to-start performance. The car identifies the key's existence by means of radio waves. These are the most pricey to replace due to the complex file encryption and programs required.
