Our take on the Evanshow Fingerprint Door Lock Biometric Door Knob with Keypad Keyless Entry

The Evanshow 190BT is a keyless door knob that unlocks five ways: fingerprint, keypad code, NFC card, mechanical key, or the Tuya app. It fits doors 1.18 to 1.97 inches thick and works on either left- or right-handed doors. At $31.99 at Amazon as of November 4, 2026, it sits at the low end of what smart locks cost, and it is the only new price listed.

Questions and answers

Is the Evanshow fingerprint lock worth it?
At $31.99 it is a cheap way to add fingerprint and code entry to an interior door. Do not expect the build or security of a $150 deadbolt lock.
Will it fit my door?
It fits doors from 1.18 to 1.97 inches thick and mounts on either side. Measure your door thickness before ordering.
Does it work without the app?
Yes. Fingerprint, keypad, NFC card and the mechanical key work without a phone. The Tuya app is only needed for app unlock and management.
Can I use it outdoors?
Evanshow does not state a weather rating for this model. Treat it as an interior door lock unless the listing says otherwise.
What is in the box?
Expect the lock, mounting hardware, keys and NFC cards. Confirm the exact contents on the Amazon listing before buying.
When is it cheapest?
Only one store lists it new, at $31.99 as of November 4, 2026. Watch for Amazon coupons and Prime Day or Black Friday discounts.
