1: If you are a vendor or property owner and want to get the lockbox codes by text  message (SMS) please email  with          the cell # you would like to use to use and once you get an email confirmation that your cell # has been added then follow  the                    instructions below 

2: Access codes can be obtained by sending a text message to 312-971-6474 and using the prefix sdcpm plus a dash plus the lockbox              serial number, like this  example: sdcpm-10001111
    You can get the lockbox serial # from the back of the bottom of the box 
3: Within 1 minute you should receive a text message from (312) 313-2227 with the code.
      Eg  "Here is the access code for 2905 Columbine Street. It is valid for one use, today only. The lockbox code is 9826."

4. To open the box, enter the 4 digit code provided and hit the "Enter"  and the screen display will  tell you to "push the door" after                  which it will open and you will be able to remove the key. Put the key back to use and close the door, which will then lock automatically.  

5: The code will work all day, however, once you have used it, if you need to leave the property and return later, after 2 hours you will               need to request a new code.
