Maintenance
Battery Life and Recharging
The Tapo DL105 is powered by a removable, rechargeable lithium-ion battery pack, offering up to one year of battery life under typical usage (based on 20 unlocks per day in Wi-Fi mode). For recharging, use the built-in USB-C port and the provided USB adapter cable. This eco-friendly design eliminates the need for disposable AA batteries.


Weather Resistance
The exterior assembly of the Tapo DL105 has an IP54 weather resistance rating, providing protection against dust and splashing water. This ensures reliable operation in various weather conditions, with an operating temperature range from -22℉ to 158℉ (-30℃ to 70℃).

Troubleshooting
Preventing Unauthorized Access
The Tapo DL105 includes features to enhance security and prevent unauthorized entry:
- Auto Lockout: The lock automatically enters a lockout period after multiple failed attempts to enter a passcode or fingerprint.
- Real-Time Alerts: Receive immediate notifications on your Tapo App for any suspicious activity, such as incorrect entry attempts.

Notifications Not Coming Through
If you experience issues with notifications not being sent through the Tapo app, while the lock otherwise functions normally, a simple solution is to remove and reinsert the batteries. This often resolves the notification delivery issue.
Door Not Latching Properly
If the door does not latch perfectly, the lock's strength is designed to be robust enough to auto-lock without jamming in most cases. Ensure the door frame and strike plate are correctly aligned during installation to minimize such issues.
