Keys to your rental properties

[Sam Leon]

If you have several rental properties in various locations (I don't mean multiple units in same building), is there any reason I shouldn't key them the same?

In other words, I had one property that I changed the front, back, side doors and they all have the same key. Now I am changing locks at another property and I am thinking to key the cylinders the same. When I change locks on the other two I might do the same.

To me that's very convenient, I know they have the same key but my tenants don't. Can anyone think of a reason why I shouldn't do this?

True, you know that. But now Sam Leon, if your tenants Google your name and find this post, they will now know that their key might work on your other properties.

I always key all my properties separately and no one but the tenants and myself have the keys.

Whenever I buy a property or when someone moves out, I always change the locks.
