I love this keyless entry lock! Affordable, easy to install, easy to download the TT lock app, easy to set up and manage the lock. I want one on all my doors honestly. Never need a key but can use a key if you want to use a key. The keyhole is hidden behind a secret magnet cover on the knob. It uses code entry, fingerprint entry, and a key fob entry. Every programmed entry option is named separately such as John's fingerprint or keyfob%231 or Drew's code. Whenever that way enters the door, it's recorded. I can see that someone's fingerprint entered at so-so time and then a key fob %232 entered at this time. Love this. However I don't recommend paying the $88 installation fee for a pro to install. The Angi app they use didn't find a pro by time of the appt they scheduled and then they rescheduled. Waste of time and money.
