Key Management System - Master Key and Easy to Re-key at Turnover

[Joe Norman]

How are property managers/investors who have mulitple units (50+) handling key management? I’d love to have something with a master key and also something thats easy to re-key.

• - landlordlocks.com seems like a great option, although their website is terrible which makes me question their professionalism - anyone have experience with them?
  
  
• - Kwikset Smartkey looks like its easy to re-key at turnover, but I don’t think it has the option to create a master key - am I missing something?
  
  
• - Kiwkset 816 Key Control Deadbolt - this one has two cylinders so I think one can be a master key, and one can be rekeyed for tenants at each turnover - anyone using these that can confirm?
  
  
• - Anyone using electronic keypads? Are there good options that don’t require them to be connected to the tenants wi-fi?
  
  

Any other options or things I need to consider when putting together a forward looking plan for large scale key management?

Thanks in advance for your insight and advise!
