Kwikset - Halo Smart Lock Wi-Fi Replacement Deadbolt with App/Keypad/Key Access - Satin Nickel

No. There is no way to do this. My recommendation would be replace the locking knob with a pass-through knob so that you can always have access. I've noticed a trend of no longer using both a deadbolt and a locking knob and just having a deadbolt. In my case I replaced the locking knob with a Juno signature series passthrough knob. The signature series knobs are the nicer knobs and the juno series knob in venetian bronze is a great match for the keypad.

Yes, the Halo Smart Lock has the SmartKey technology which allows rekeying the lock at any time to the other Kwikset key but is not compatible with other brands.

The Halo works with the Kwikset app and is compatible with Amazon Alexa, Google Assistant, and Brilliant The Vivint system is compatible with Z-Wave home connect locks, linked here: https://www.kwikset.com/search?FilterCriteria.Query=z-wave&FilterCriteria.Tab=products

Short answer is Yes and there is a history log for each lock. Longer answer is there are two types of users. App users, and keypad users and they are separate and both are logged when they do things to the lock. keypad users don't have to have the app installed. You create keypad users with access codes. Those access codes are stored in keypad. When a keypad user enters their keypad code, you will get a notification. There is also a log in the lock that you look at where this is running history off the accesses date/time, and user. Then there are the app users. These are people that have the app installed and can use the app to lock/unlock the app. You also get a notification when one of these app users uses the app to lock/unlock and it shows up in the history log. These two types of users are different and separate. In my locks I keep them the same name to avoid confusion. Integration with Alexa is very good. You can lock, unlock, and even asks status of the lock. To unlock you will need to assign a unlock pin in alexa.

Yes, the Access Codes can be edited, deleted and added at any time by using the Kwikset App.
