And yesterday I had my first “Locked myself out” event. Keys in hand, but since I was just going to get my mail I forgot I needed my phone, and that after the installation the door locks behind you automatically. I had the 7 digit code written down in my wallet, which was also in the apartment. Had to get a neighbor to call my daughter (thankfully I remembered her number) to give me the code. New code is now in my wallet, in my car, and all my daughters have it as well.
It would be so much better if you could pick your own code, but all you can do have them generate a new 7 digit code for you.
