168. 車両キー
車両キーは、車両を解錠し、作動を許可する装置です。従来は機械式の鍵でしたが、現代車では電子トランスポンダー、リモコンキー、キーレスシステムなどが一般的です。
多くはイモビライザーと連携し、認証済みキーを検知しない限りエンジンや駆動系を始動できません。そのため交換・複製キーは車両への電子登録が必要な場合があります。
What does a modern car key do?
A modern car key can unlock and lock the vehicle and authorise the engine or electric propulsion system to start. It may use a mechanical blade, electronic transponder, remote-control functions or a keyless system.
What is a transponder key?
A transponder key contains an electronic identification device that communicates with the vehicle's immobiliser. If the correct code is not recognised, the vehicle normally prevents the engine or propulsion system from being started.
What should you do if you lose a vehicle key?
Use a spare key if available and arrange a replacement through an appropriate dealer, locksmith or vehicle specialist. Modern replacement keys often need to be programmed to the vehicle's electronic security system.
