I'm interested in your smart lock products and would like to get more details about the password features. Could you please provide information on how the password mechanism works? I'm particularly curious about security protocols and any additional functionalities your locks might offer. Additionally, if there are different models available, I'd appreciate a brief overview of their specifications and pricing. Understanding these details will help me determine which option best suits my needs and if I should move forward with a potential order. Thanks for your assistance!
