I purchased the Schlage electronic deadbolt to allow entry into our house in case I didn't have a key with me. It works very well. Only drawback that I see is that it needs to be placed on a solid door without a glass panel as the lock has a lever on the inside that operates the deadbolt. There is no option for key locking from the inside, only the lever. Locks only keep honest people out, so it's better to have a deadbolt that is key lockable from both sides if you have an exterior door with glass panels. No need making it easier for a thief to get in than is necessary.
