To unlock the car, go to the booking in SnappCar app and click on 'Check-in'. You can open the car at the last step of the check-in process. After unlocking the car through the app, you can use the keys to open and close the car until it’s time to check-out. If you cannot open the car at check-in, always check if you are standing at the correct car. If you have found the correct car and it won’t open, please contact us using the contact form below.
