Important! SentriLock Lockbox Shortage 

As of July 2021, SentriLock is experiencing a national shortage on the parts used to make lockboxes. Because of this shortage, effective immediately, Mainstreet is limiting the purchase of lockboxes to one per person, per month. If you would like to purchase a SentriLock Box, please call 630.324.8400 to place your order.

What are your options if you aren't able to purchase a lockbox?

  1. As a Broker, you may have the ability to borrow a lockbox from your Managing Broker. Please check with them to see if that is the case. 
  2. You also have the ability to borrow a lockbox from another agent. In order to do this, you will need to call SentriLock at 877.736.8745 to get instructions on how to access the box.

Do you have SentriLock lockboxes you would like to sell or transfer to another agent? 

SentriLock lockboxes can only be transferred between members of Mainstreet. Just fill out and submit (submission details included in the form) Mainstreet's SentriLock Lockbox Transfer Request form.

Mainstreet will keep members updated about inventory and potential future solutions.
