What to do with all these keys?

[Rob Donovan]

How do you guys keep all your keys organized? I don't have that many units yet, but already all these keys are a hassle. On a similar topic, what do you do about changing locks? Is there a good landlord lockset that is easy to change out and keep the keys manageable? Thanks in advance.

btw, there are NUMEROUS great threads on keys on here.. numerous.
