No. The beauty of the Latch application is that your credentials will automatically expire in accordance with the lease end date and time detailed on your lease agreement.
If, for whatever reason, you were provided with a back up unit key or any additional physical keys for the building, it is your responsibility to ensure they are left on the unit counter before vacating the premises for good.
For any other questions regarding the Latch application or device, we encourage all residents to visit "I Live in a Latch Building" resident page. It includes several FAQs and helpful hints to get the most out of the system.
