We're sorry you're having trouble with your SentriLock Generation 3 lockbox. Below are steps to generate a Cardless Clock Code to reset the lockbox.

  1. Navigate to the SentriLock Access page of your account.

  2. Click "Get Code" under the appropriate serial number.

  3. Select "Cardless Clock Code" as the Code Type

  4. Click "Get Code" to generate the Cardless Clock Code

  5. The Cardless Clock Code has been successful when you hear 4 rapid beeps.

  6. Once you hear the beeps, generate either a One-time Code or Shackle Code as normal to confirm.

Note: the Cardless Clock Code is time sensitive, so you will need the lockbox in hand when generating this code in order to enter it into the lockbox at that time.

**If you do not hear the beeps please repeat the process again but this time with the battery adapter connected to the lockbox. There could be an issue with the battery being low. If it works with the battery adapter plugged in, that tells you the lockbox needs a new battery!

If the Cardless Clock Code to reset the lockbox does not correct the issue, please complete the SentriLock lockbox troubleshooting questionnaire. We'll ask some quick questions to better understand the problem and hopefully provide the steps to resolve the problem. If the issue cannot be solved by the suggestions in the form, you will be asked to provide more information and our team will help troubleshoot further.


Additionally, each SentriLock Generation 3 lockbox is covered under a 6-year warranty. Please follow this link to review the Tenant Turner SentriLock Limited Hardware Warranty

Note: A SentriLock battery adaptor is required to troubleshoot mechanical malfunctions of SentriLock (Generation 3) lockboxes. We are unable to provide a free battery adaptor kit, even if your SentriLock lockbox is under warranty. Please consider purchasing at least one battery kit to have on hand for your office. If you need to purchase a battery adaptor kit, please contact our Tenant Turner Support Team.

Important Note: If a replacement lockbox is being shipped to you, please return the malfunctioning lockbox within 10 days; otherwise, the provided shipping label could expire and the package will be discarded by the carrier.
