At Cinnamon Ridge III we had SafeLoc for years. Card failures became common and of course support became a problem. In 2020 after soliciting proposals from several vendors we settled on Remote Lock. It is a keypad system that is wifi connected and networked. Our management company is the primary administrator, but the unit owner can monitor the lock as well as assign codes...as well as many other owner-assessable features. Also other individual unit management companies can have the similar access for lock management. We remain satisfied with the system.
Our unit owners, guests, and management company have been quite satisfied with the keypad system. So much better to have the access code in your head than buried in a ski jacket pocket or mistakenly left sitting on the kitchen counter.
We've had a couple of lock failures over the years but nothing that seems out of the ordinary for electronic devices.
Regarding batteries, the battery health is readily displayed on the lock's app dashboard, both for the unit owner and the administrators.
There are probably more features / options on lock choices today than what we had in 2020, although we remain satisfied with our current lock. But our lock doesn't have an additional deadbolt function that can be engaged from the inside. About the only comments we've had about the lack of deadbolt is the concern about more security to prevent a person with a valid code (a maintenance person?) to entering a unit when it is occupied. It would be worth checking if a deadbolt function is now available.
During the SafeLoc days we lost control of our managing agent have access to all units. We took the opportunity with the new lock system to have a strong policy that all units had to have the new keypad system and to not have other overriding locks. Unlike the SafeLoc system we had, other management companies have wide ranging control of the keypad system so a common reason for losing control was eliminated. We have not had any pushback from owners on this policy.
