The keys and locks themselves are very durable and difficult to pick. You register as a card holder for the lock and then only the card holders can get new keys cut which means you can monitor key holding, i.e. your cleaner cannot get their own key cut. Personally I like the look of them and the keys are slimline therefore easier to carry in a bunch which is handy for me as I have to carry the keys to a few properties. They are a bit better than most locks I fit in terms of operation and reliability. If you have a letterbox in the front door a thumb turn can be a liability anyhow.
