SMDRA SentriLock FAQs

How do I get a SentriLock?

To set up a SentriLock account, please visit your primary local REALTOR® association. SentriLock accounts take approximately 20 minutes to set up, and do not require an appointment.

Do I need to set up an appointment?

No, you do not need to set up an appointment, although SMDRA does recommend calling ahead of time to ensure a member of SMDRA staff will be able to fully assist you. If you have recently transferred association membership, please check the local MLS to make sure your account information with them is correct before setting up a Sentrilock account. Sentrilock routes through the MLS, and SMDRA cannot setup your account if your association membership information is incorrect.
