Unlock MLS maintains key reciprocity agreements with the Houston Association of REALTORS®, San Antonio Association of REALTORS®, and the Four Rivers Association of REALTORS®. Unlock MLS maintains key reciprocity agreements with the Houston Association of REALTORS®, San Antonio Association of REALTORS®, and the Four Rivers Association of REALTORS®.

We’re always looking for products and collaborations that provide new and substantial value to our subscribers and their businesses.

As an Unlock MLS subscriber, you can now access and show almost 50,000 more properties in the Central Texas, Houston, and San Antonio areas. No additional set up, fees, or subscriptions are required!

Each of the counties served by each respective MLS, in addition to listings submitted to each system from other geographical areas, will be included. With the addition of HAR and SABOR key reciprocity, you can now show listings across nearly 70% of the Texas housing market!

No! This latest key reciprocity collaboration is your newest Unlock MLS benefit and is fully included in your Unlock MLS subscription.

Nothing! Key Reciprocity with HAR and SABOR automatically went into effect on January 31, 2024.

There ARE a few exceptions. Reciprocity does not extend to CO-OP keys purchased with another organization. For Key Reciprocity to work:

1. You must subscribe to Supra eKEY through Unlock MLS;

2. You must use a Supra lockbox at your listing; and

3. Agents accessing your lockbox must also subscribe to Supra eKEY through HAR or SABOR.

No. The Key must be assigned by Unlock MLS or one of the organizations with which we have a reciprocal key relationship.

At this time, you must be a subscriber to the HAR and SABOR MLSs to access showing data for listings in these marketplaces. You can view showing data in their systems or through a tool like RPR.

If you’re not a subscriber to the system the listing is in, you will need to contact the listing agent to obtain showing instructions.

We understand the value of showing information and look forward to the possibility of additional collaboration with HAR and SABOR in the future.

Yes! If 1) your Supra eKEY subscription is with ABoR/Unlock MLS and 2) you are using a Supra lockbox on an Unlock MLS listing, then any agent who has their Supra eKEY assigned by HAR or SABOR will be able to show your listing without subscribing to Unlock MLS.

Yes! Unlock MLS’s long-standing key reciprocity agreement with the Four Rivers Association of REALTORS remains in place.

As always, Supra tracks all lockbox showing activity. If/when a lockbox is opened by an agent with HAR, SABOR, or Four Rivers, their Supra information will be included in your lockbox’s Showing Report.

Professionalism and showing etiquette are a core practice for all Texas real estate professionals. You should always closely review and follow all showing instructions before showing a listing, no matter what marketplace you’re working in. If you do not have access to a listing’s showing instructions, directly contacting the listing agent and/or brokerage is the appropriate first step.

Nothing has changed in terms of lockboxes policies when moving a Supra lockbox between marketplaces. The lockbox must be deprogrammed by the existing MLS marketplace, before it can be reprogrammed by the new MLS marketplace.
