I just changed the batteries in my DL100 lock and now it won't turn on, I tried multiple different batteries and resetting. The power bank USB c backup method works but as soon as you unplug the power bank, it turns right back off.

What battery did you use? Please share some pictures here or the purchase link. How are the batteries installed? Can you share a picture here?

  @Wayne-TP I used regular energizer AAs and ensured I put them in the correct way about 4 times.

  @Sheldonbush14 I'm having the same problem. It's impossible to email about help. If you don't mind send me the email of whoever you had so I can try to get some help myself

Have you tried using batteries from a different brand? It might be worth switching them to see if that helps. If the problem persists, please follow the steps mentioned earlier and email our support team for further assistance (replace the forum nickname with yours).
