[Depricated] Lock Code Manager

Welcome to SmartThings. It sounds like you have installed things correctly as you are getting user reports when they open the lock so I’m not exactly sure of your issue. What I would recommend is uninstalling the Lock Code Manager SmartApp and migrating to the new one as this product is no longer supported by the author. You should be able to use the same DTH (device handler) you have installed, but in case there is a change I’d recommend just installing everything from scratch. If you still run into issues feel free to ask in the thread I’ve added below and we’ll do what we can to help.
