  • Why did MIBOR make the switch to Master Lock?
    The move to Master Lock helps us to accomplish our focus of moving together, forward and provides a more simplified mobile experience to our members.

    Listing inventory levels, paired with SentriLock lock box shortages and the additional changes SentriKey has announced about their products and services, make this the best time for this transition.  

  • What is the cost of a Master Lock lock box?
    Master Lock boxes are available for purchase for a discounted price of $70 plus tax for MIBOR members (retail $146). 

  • Do I need to download the Master Lock Vault Application?
    This application will only be used for lock box owners to take ownership and manage the settings of their lock boxes. To efficiently process the assignment of your new Master Lock Bluetooth electronic lock boxes, please download and login to the Master Lock Vault Enterprise application on your mobile device. You login credentials will be found in an email from

    All MIBOR  BLC subscribers have access to MIBOR's showing and property access system powered by BrokerBay. BrokerBay can be used to schedule and manage showing appointments, provide 3D virtual showings, issue and track communications, review analytics and more. Visit for more information.

  • What happens if my electronic Master Lock box battery is dead?
    A 9-Volt battery applied to contacts on the bottom of the box will charge enough to open the box and change the internal batteries.

  • What happens if my electronic Master Lock box is unresponsive, but not due to a battery issue?
    If the lock box is under warranty, Master Lock will cover the replacement. Removal from a property will be the responsibility of the listing agent/brokerage.
  • I work in a market that uses a different electronic lock box provider predominately. How will other agents receive access to properties using my Master Lock lock box?
    Access to the lock boxes, regardless of brand, will be transmitted through the showing solution utilized. Whether using the MIBOR BLC showing solution powered by BrokerBay, or an alternative solution contracted by the brokerage, either will be able to facilitate access to the lock box either by bluetooth through the app or by providing a temporary access code specific to the listing appointment. 

  • Are MIBOR members required to use these lock boxes?MIBOR does not require the use of an electronic lock box, however we support the use because of the additional security and audit functionality provided through their use.

  • What do I do with my SentriLock lock box?
    We are no longer exchanging SentriLock lock boxes. If you are in possession of SentriLock lock boxes, please see the recycling information below.
  • Should I drop my SentriLock App? Does it have any further use? SentriLock will be retired from the MIBOR services on March 1, 2022. Beginning on that date, there will be no use for the SentriLock app. The app will not function after this date. Until then, the app will be necessary to gain entry until our contract is fully expired on March 1.

  • How will MIBOR members schedule showings outside of the MIBOR Service Area once SentriLock is replaced?

    Beginning Tuesday, March 1, 2022, MIBOR’s contract with SentriLock expires and MIBOR will have no access to manage or transfer SentriLock lock boxes. SentriLock boxes within the MIBOR service area will no longer be operable at this time.

    If an agent is also a member of another association/MLS that continues to offer a different platform such as SentriLock, those services will continue to be available.

    For MIBOR members, the reciprocity arrangement previously controlled through SentriLock will now be in the hands of the agent at the time of appointment request.

    A non-MIBOR agent can set up showings on a listing by contacting the listing office/agent to request an appointment. The listing office or agent can then set the showing up through MIBOR's Showing and Property Access Platform, powered by BrokerBay. The confirmation for the showing will include a code for the lock box that is good for the appointment time. The non-member may also choose to call the Appointment by Phone number on the listing 317.218.0600, Option 1

    All other conditions of the showings are negotiated as usual for non-MIBOR members. If a MIBOR member wishes to show a property in another service area, they will simply schedule the appointment as usual through the method determined by the listing agent. Access arrangements are then provided through the method of the listing agent’s preference.
