I'm reaching out regarding a Lei-u lock that I previously purchased. I'm currently trying to reset the lock so that it enters pairing mode, but I'm not sure about the correct steps to take. It's important for me to get this working as I'm looking to connect it with my smart home system, and any assistance you can provide would be greatly appreciated. Could you please guide me through the process of resetting the lock? If there are any specific instructions or tips to ensure it goes into pairing mode successfully, that would be really helpful. Thanks in advance for your support!
