Member Benefits


The SUPRA Department at SLAR oversees the Lockbox System used by REALTORS® on the St. Louis side of the metro area. SUPRA, the leading industry lockbox vendor, provides the backbone of the system through its SUPRAWeb website. The SUPRAWeb website synchronizes showing activity of properties to a virtual private network and receives 24-hour agent updates and showing feedback providing a more efficient, safe and secure environment for both the homeowner and REALTOR®. Members may use their iPhone, Blackberry, Android or other smartphone to access the Lockbox System and download daily MLS listing information for portable use. This is called converting your phone to an “E-Key.” There is also a standard “Active Key” that is available for use in the system for REALTORS® preferring not to use their smart phones. The “Active Keys” are leased from SUPRA by the members for an annual lease fee. The “E-Keys” or smartphones are charged a monthly service fee through a debit to an online credit/debit card or checking account.
