All You Need To Know About SentriLock

You may already be aware that beginning March 1, the Mainstreet Organization of REALTORS® will discontinue the use of contractor and one-day codes to gain entry to properties listed by MainStreet REALTORS® or using a Mainstreet issued lockbox.

NOTE: THIS ONLY APPLIES TO LOCKBOXES USED BY MAINSTREET MEMBERS. C.A.R. and other local associations HAVE NOT implemented this practice.

To show these properties, you will now need to take one of the following actions:

  1. Arrange for the Mainstreet listing agent to meet you at the property
  2. Arrange to pick up a key for the property from the listing agent
  3. Use your SentriCard or the new SentriSmart mobile app to gain entry to the property

SentriSmart is a new mobile application which allows access to a lockbox key compartment with the use of a mobile access code instead of a SentriCard. The primary advantage to using the app is that it’s readily available and does not need to be updated. However, YOU STILL NEED TO PURCHASE the SentriCard to be able to release the shackle, assign the box to a listing, turn “Call Before Showing” on/off and customize showing times. All other functions are available through the SentriSmart app.

The SentriSmart app is now available to C.A.R. SentriLock subscribers for their iPhone, iPad and Android. YOU MUST be a SentriCard subscriber to have access to the SentriSmart app.

To download, visit the App Store or Google Play from your smartphone and search for SentriSmart.

The SentriCard and SentriSmart mobile app can be purchased together for a pro-rated cost of $28.50, which covers the period through May 31, 2014. On June 1, 2014, the annual cost of the SentriCard, which includes a two-year service agreement, will be $96 plus Illinois sales tax (reduced from $114). Please note NO REFUNDS will be granted.

The development of the REALTORS® Lockbox was based on the features most requested by REALTORS®, including:

  • An integrated and illuminated keypad
  • An extra large front opening key compartment
  • One-Day Access Codes for your distribution (up to nine per day)

  • Optional cardless entry
  • Tracking Security
  • Homeowner “do not disturb” setting
  • Call before showing
  • Variable showing hours
  • Convenient credit card-sized SentriCard that also serves as the electronic "key card" for the lockbox
  • NEW! Access to SentriSmart App

SentriLock's system is web-based so that lockbox settings and showing information are easily accessible from any internet connected PC. Through the ease of a card reader in your home or office, in less than 60 seconds your SentriCard is updated and ready for you to use.

How Do I Obtain SentriLock?

Visit any one of our C.A.R. locations to obtain your SmartCard and lockbox. Please visit during our regular office hours to purchase the lockbox or card reader; however, you must schedule an appointment. Please make an appointment by sending an e-mail to lockbox@chicagorealtor.com with the following information:

  • Your name
  • C.A.R. member ID
  • C.A.R. location you prefer to pick-up from along with a date and time

You will receive a confirmation e-mail when your card is ready for pick-up, which will be within 24 hours from the time of your request.

** Please note that access to the Card Reader is necessary in order for you to update your SentriCards. If you will be sharing a reader within your office or with another agent, you may elect to not purchase the Card Reader.
