I'm reaching out regarding a Guub digital lock that we're having trouble accessing. Unfortunately, we've misplaced the master code and are unable to locate it in our records. The serial number for our lock is clearly indicated, but we need your assistance to retrieve the master code to regain access. Could you please guide us on how we can obtain the master code? Any documentation or procedures you could provide would be greatly appreciated. Our team is eager to resolve this issue as soon as possible, so your prompt response would really help us out. Looking forward to hearing from you soon!
