SnappCar Keyless is a piece of hardware technology that owners can install in their car. This technology allows renters to open the car using the SnappCar app, which means that the owner does not have to be present for the key exchange at check-in. Keyless cars can be identified by the blue icon in the search results, shown below. More information about SnappCar Keyless for owners can be found here for Swedish owners and here for Dutch owners.
