Tapo DL105 fingerprint door lock drops to $79.99 on Amazon with free shipping

Amazon is selling the Tapo DL105, a Wi-Fi deadbolt lock with a fingerprint reader and a keypad, for $79.99. Two deal reports, from Slickdeals and TechBargains, list the same price, and both say shipping is free. Slickdeals says a community member shared the offer, so the report is based on a tip rather than an announcement from the maker. The price is listed as $79.99 or less, so it may change.

The lock offers six ways to open the door. These are the fingerprint reader, custom keypad passcodes, the Tapo app, close-range Bluetooth, a smart home voice assistant, and backup keys in the box. The fingerprint reader is said to unlock in half a second and to store up to 100 fingerprints. Owners can set up resident profiles with permanent codes. They can also create one-time or scheduled codes for guests, delivery staff, contractors and cleaners.

Power comes from a built-in battery, which the listing says lasts up to one year per charge. The battery recharges through a USB-C port, so the lock does not need disposable AA batteries. The device is rated for temperatures from -30 to 70 degrees Celsius and carries an IP54 rating for water resistance. The maker says it installs on standard lock holes without new drilling, in under 15 minutes. The listing names two common hole sizes, so buyers should measure their door before ordering.

Security features include an automatic lockout after repeated failed attempts and real-time alerts when the lock detects suspicious activity. The Tapo app keeps a log of lock and unlock events with timestamps, so owners can see who entered and when. The lock can also relock after a set time. It can be paired with other Tapo or Kasa devices, for example to lock the door when smart lights switch off. TP-Link says it has signed the Secure-by-Design pledge run by the US Cybersecurity and Infrastructure Security Agency. The listing does not describe independent testing of that claim.

The two reports agree on the product and the price. They differ only in how precise the price is. Slickdeals gives $79.99 or less, while TechBargains lists exactly $79.99. The sources do not say how long the offer will run, how much stock is available, or whether the price applies outside the United States. Readers in other countries should check the local price before they decide.

Voice control is supported through Alexa, Google Home and Samsung's SmartThings platform. This suits people who want keyless entry that fits into an existing smart home. Renters may also find it useful, since it installs without new holes. The sources do not say whether the lock works with every door type, so check the fit before buying.

This is a sale on an existing product, not a new launch. The sources give no review scores or long-term test results. Readers who want independent findings should look for a full review before they buy.
