Only you and a renter with an accepted booking can open the car.
Your car key remains safely stored and is invisible from outside the car.
SnappCar Keyless uses your immobilizer as extra security. Even if there is a break-in and the key is somehow taken, the car cannot be started.
You can see where your car is at any time via the App, except when there is an active booking (to protect the renter’s privacy).
