Use your smartphone as your lockbox key. The eKEY™ application uses your phone’s wireless communications so you can do business anywhere. Find out how to get a CORE SUPRA eKEY here.


Two service levels are available: eKEY Basic for common keybox functions, and eKEY Professional which enhances basic capability with added business tools such as MLS data stored on your phone (eliminating time consuming over-the-air searches), linking the listings to Google maps, and displaying showing details on your phone.

eKEY Basic – $20.53/month

eKEY Basic turns your smartphone into a lockbox key. It also enables you to program iBoxes, change shackle codes, and more.

eKEY Professional – $27.96/month

Like eKEY Basic, eKEY Professional turns your phone into a lockbox key. It also adds many productivity features to your smartphone with enhanced MLS capabilities. Learn more here.
