If you push a Start/Stop button on the dashboard of your vehicle to start your engine, your key is called a Smart Key. Smart Keys are almost always more expensive than normal Transponder Car Keys. Fortunately, Replacement Car Keys can provide you with a new Smart key whether you’re after a spare, or if you have no keys at all.
If you’re down to your last Lexus Smart Key, it’s important to act now. It’s always much cheaper and easier to have a spare Smart Key programmed, than when you have no keys at all.
