Not a Realtor can I use a lockbox?

[Ryan Dossey]

I have had Realtors just give me codes to investment properties which makes it nice and easy to tour the property with no pressure. For people I have already worked with I would like to be able to offer the same courtesy. Are there any good lockboxes you guys use? I would rather spend a decent amount and have a high quality unit vs something a hammer could shred. Thoughts?
