Smart Lock Guest Access - Code 251

I use the “Smart Lock Guest Access” SmartApp to manage guest codes on my smart locks.

For some reason, a couple of the Yale locks say they have “Code 251” under Lock Codes, but 251 is not an actual door code. Code 251 notifications are triggered when the master code is entered. There is no way to delete these false 251 Codes.

Anyone else encounter this / have a fix?

How long have you had these locks? Perhaps deleting the master code or a factory reset might help?

If you have access to rboy apps, use this custom DTH to address this issue (and more).

In general one should avoid using master codes to operate locks since it’s a security risk, you’re better off using user codes.
