Can you start the car without the key inside the car?

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. No, the vehicle should not start without the key inside - and inside reasonably close to the start/stop button. If it is starting anyway, I would suggest there is another key fob in the vehicle somewhere. Or, some kind of modification for aftermarket device may be present making this possible. Hands on inspection and testing is needed. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554. We'll gladly find you a certified RepairPal shop in your area.
