One of the main advantages of a keyless door lock is the fact that you will not be required to carry a key. This makes it less likely that you'll lose the key and have a difficult time getting in to the home. It also means that you won't need to store a spare key somewhere on your property, as many home owners currently do. This poses a security risk, so eliminating the need for that additional key helps to make your home safer.
