Lockbox Guidelines

London Towers South and North (Middlesex Condominium Corporation #173) only permit Supra lock boxes on the property. Any other types of lock boxes will be removed without notice.

Several LSTAR Members have compiled a list of Condo Buildings/Projects with Lockbox Policies. Many locations do not allow mechanical lockboxes, and they will be removed by the building superintendent.

Before placing your lockbox, you must register it with the building manager. If it is not registered, it will be cut off without notice. Only approved lockboxes are allowed; all others will be removed after March 31, 2026.

Condo listings come with a few extra layers of responsibility. Before installing a lockbox, make sure you’re complying with both MLS® Rules and the specific requirements of the condominium corporation.

Effective immediately, only Supra-brand electronic lockboxes are allowed. Combination or mechanical lockboxes are prohibited. READ THE COMPLETE POLICY HERE.

LSTAR has determined that many members were automatically authenticated into the BrokerBay/Supra One system and therefore are not fully aware they have subscribed.  Due to this, the system has automatically assigned a PIN instead of letting members choose their own. 

Because of this, many members don’t know that there is a specific BrokerBay/Supra One PIN and are using their old Supra PIN, which won’t work.

Effective August 28, 2025, LSTAR will no longer provide Supra access. Please review this information to ensure uninterrupted access to lockboxes in LSTAR's jurisdiction. Also, please feel free to include this PDF on your listings to share with non-LSTAR REALTORS®.

When listing a condominium, it’s essential to understand and comply with the lockbox rules set by each Property Management Company. Requirements can vary by building, and failing to follow them could result in penalties or the removal of your lockbox. Here are some important guidelines to keep in mind.
