Have a Weiser one at home with the smart key. No idea if Schlage has something comparable, though a locksmith should be able to pin the deadbolt to your current key either way.
Got nearly the same situation, my wife locked herself in our second apartment ( we usually have there a couple of tenants), she was cleaning the apartment for new rentals, I don't even understand where she could put the key, cuz obviously she used the key to get inside, but we had to call locksmith barking to get her out. I wish I could leave her there for a couple of days, but the kids where kida worry and I would have a bigger headache if I would leave her. Gladly the locksmith barking was a top guy and he did his job fast and well, the paycheck was smaller than I was expecting so no big harm for my wallet. I hope next time she will be locked with our kids, maybe I'll have a couple of days of peace. Who knows?
We though to keep the key outside but its a flat and we weren't sure we will find our key next day on the same place
Have these on all of our doors and door to the shop. Full metal internals, no plastic internals to strip, no batteries to die. 100 percent reliable....... my 2 cents anyway
