Please find below all the troubleshooting steps that you might need.
1. Check if you have used the PINs within the timeframe. The PINs will expire if they are not used within an activation time frame. Please see the guide below.
One-Time PINs must be used within 24 hours after creation
Permanent PINs must be used within 24 hours after creation
Recurring PINs must be used within 24 hours after creation
Duration PINs must be used within 24 hours of start time
Bluetooth keys must be claimed within one hour after creation
2. Please sync your lock. Within Bluetooth range, please go to the Settings page and tap on sync. Try to use the PIN again. (If you are not within the area, you can ask your property manager to download the igloohome app and share your credentials).
3. Generate another PIN and see if that works.
4. Unpair the lock and pair it again then generate PINs and use. This should fix the problem.
If this doesn't work, please take a screenshot of the activity logs and send it to us. We will further troubleshoot.
