Please allow the auto-lock delay to exceed 4 minutes. When Sesame is set up so that it can unlock by geofence (such as with QSesame or the newer HomeBridge plug-in, or for when you add HomeKit support), you will often need a longer delay so that you can park and get inside before the auto-lock occurs. But even when relying on the app as is, it is not uncommon to want to walk out and do some chore that takes a short while and not have the auto-lock occur. So, I suggest allowing quite long times to accommodate whatever people might need. Possibly up to a few hours, but I suggest that the maximum delay should not be any less than one-half hour.
