Key Reciprocity with Austin’s MLS

HAR has entered into a Supra key reciprocity agreement with the Austin Central Texas Realty Information Service (dba Unlock MLS), a wholly-owned subsidiary of the Austin Board of Realtors®.

Agents with an HAR Supra eKEY are automatically able to open up Supra lockboxes in the Greater Austin area without additional set up, fees or subscriptions. Likewise, agents with a Supra eKEY issued from Unlock MLS will be able to open HAR Supra lockboxes without further effort.


This is similar to the Supra key reciprocity agreement announced last year with the San Antonio Board of REALTORS® (SABOR). Now HAR members can access and show properties across Central Texas in addition to properties in the San Antonio area.


Of course, you must always request and receive confirmation of your showing appointment from the listing agent or their showing service before entering a property.


This marks the initial phase of ongoing cooperative efforts between HAR and Unlock MLS. Stay tuned for more news on future collaborations as the year progresses. It is all part of HAR’s ongoing efforts to enhance our members’ abilities to serve their clients and expand their businesses and referral opportunities.


Thank you for your continued support, and we look forward to continuing to provide you with valuable resources.
