Key-less or remote access locks for multi-family units?

[Erik Hopperstad]

My partners and I are currently invested in multi-family properties in rural areas. We currently have onsite management that is overseen by our in-house property management company but we're looking for further efficiency. Is anyone aware of a key-less lock system that we can use on our properties? I'm asking specifically for each individual unit, not the main entrances. Ideally, we would be able to change the "code" or "key" remotely so we wouldn't have to physically visit the sites to accomplish this. Any info, suggestions or first hand experience would be greatly appreciated!

@Erik Hopperstad, I've toyed with the idea of Kwikset's Kevo bluetooth deadbolt where you can remotely send/activate/inactive bluetooth keys to the lock without wifi...but they're very expensive at about $250. Instead, I currently use Schlage's keypad locks on my units so that I can still create and delete passcodes....so the tenants never receive actual keys (I keep the physical override keys) but it does require a person to manually change the 4-digit passcodes. I consider these locks cost effective at $110 each from Lowe's or Home Depot. They use 9 volt batteries with a battery life of 3 years, so I change the batteries every 1-2 years.
