The wifi is what will allow you to access the door remotely.If you don't want wifi on it, Then you can still get a smart lock you'll just need to pre-program several different codes into it, and then give out those codes appropriately but you'd need to be on site at the door itself to program initially or update it.From personal experience I find the touch screen or wifi locks to be complete POS's that are not reliable and the battery does not last long.
