Exactly! what I was looking for. Installation was super easy and even though there is a method to set everything up without the app just get the app first to set since it’s super easy then onse it’s set you can forget about the app and force disable ot if youn have security concerns. The option of fingerprint, the card, code and just incase key is amazing. you can also quiet it down from the app if it’s to loud. Works perfectly.. I tested other family members fingerprints to see if it was secure and it is!. Also it has auto lock so after like 5 seconds it locks but you can press button on the inside to keep it unlocked if you need to.

Meets expectations. Good material, easy to install. It’s great that you can turn on/off free pass function. Fingerprint recognition goes very well, password and key perfectly, some work very well for others it is difficult to read them (5 Come) that is why I do not give 5 stars but with the other types of access it is more than enough.
