When you return to a Geysir location, make sure the fuel tank is completely full, take all your luggage out of the car and take the keys into the office. The process usually takes a few minutes. However, if damages are to be dealt with it will take longer. It is the renter´s responsibility to leave enough time between returning the car and the flight check-in time. If you are returning after our opening hours you put the keys in our drop-box which is inside of our lobby and our staff will inspect the car as soon as our office opens.
