Re: Keyless entry for residential property?
I would be more worried about fire, say there is an electrical fault with the device and it catches fire (it can happen), now your point of exit in case of a fire is suddenly on fire. In a flat with only 1 door, being on a high floor and having the door itself catch fire doesn't seem like a good idea to me. (okay, the door itself won't catch fire, modern ones should be made of metal)
