As long as they keep the physical key tumbler access, I see no big deal.
But I;d love to see how that works.
If it replaces a key itself, I see hilarity to ensue.
It would be more fun then when I saw a guy on a production floor who forgot his box keys and had too many points against his attendance record to clock out and go home to get his keys ath he just drilled all of his locks out before the work start buzzer ran so he could do his job.
And yes, the mgmt. was happy to fire him if he was lnon-compliant and it was a $50k a year job he had.
If only a fob, now he would be running around looking for batteries instead of borrowing a drill. Hahahahahaha.
It's like cars with only one keyed door and a fob and it locks you IN like what happend to that couple a few weeks ago. My car won't let me get out! ZOMG.
Forward into the "wired in" fog.
