Do you have any specific model or features in mind? Quality and reliability of locks vary a lot between the models. It would be a good idea to do some research into the lock before buying one just based on price. You can get some excellent Yale locks for the price of a Kiwkset, albeit not as good looking but packed with features and quite reliable. Plus some locks models (e.g. 910) don’t have a full keypad and have shared buttons which leads to it’s own issues with duplicate/limited codes.
Take a look at the first post on this topic, it has a table which compares lock features and also links to posts which explained features and limitations of various lock models/brands: [RELEASE] Universal Enhanced Z-Wave Lock Device Handler for Schlage, Yale, Kwikset, IDLock, Popp, Danalock, August Pro, Keywe, Philia, Samsung
