I read on the AV TEST website about the procedures the device went through to find out how safe it is. I don’t recall any mention of electromagnetic attack. It used to be fashionable to trick electric pinball machines with electric “shocks” that would make the user play another game. How much does this affect the device? Is it resistant to such attacks? Doesn’t it fool the system and make the door openable?
Those pinball machines were quite simple electromechanical things. The Smart Lock does have more complex electronics and is not so easy to trick. So far no one has done something like that successfully from close distance.
On top of that it would need to go through the door/lock/cylinder and (some air) in order to have any practical use.
