Customer Answer:
A smart key is a type of car key that allows you to lock, unlock, and start your vehicle without inserting a key into the ignition. It uses a built-in chip and wireless signal to communicate with your vehicle when the key is nearby.
Smart keys are commonly used with push-to-start systems. As long as the key is inside the vehicle or within range, the car can detect it and allow the engine to start. Most smart keys also include remote functions like lock, unlock, trunk release, and panic.
Unlike traditional keys, smart keys combine convenience with added security. If you need a replacement smart key, it must match your vehicle and typically requires programming to work properly.
Optional Additional Info:
Smart keys are also known as proximity keys or push-to-start keys. Many include an emergency insert key for manual door access if the battery dies.
