 I've installed so many shlagging codes now, but this is the first time I've installed a shlagging code lever Usually you have to bore a second hole for the deadbolt. This makes it easier on a homeowner level one hole screw it in It's done in this case having the shlagging code smart Wi-Fi lock is really important because we have a basement apartment So upstairs if we have the landlords, let's say They can't access the tenants unit without permission obviously So they have some privacy with a code lock if you're having a contractor come in if you're having a cleaning service come in You give them a temporary code. They have access without having to give someone a key You never have to worry about losing different keys either, which is really nice You know you pass out keys you have neighbors coming in you're gonna have a pet that needs to be watched Not to mention if this is used for rental or income property an in-law suite They want their own privacy a shlagging code smart Wi-Fi lever lock is the way to go might come in handy
