2026 verdict
Where the door is a US deadbolt, the TP-Link Tapo DL100 is the smart lock with a built-in keypad.
It draws the stronger owner reception, carries IP54 sealing for a sheltered opening, and includes 2.4 GHz Wi-Fi, Bluetooth, a doorbell button, anti-peep codes, one-time codes and a physical key, with Alexa, Google and SmartThings and without Apple Home or Matter. The Nuki Smart Lock Go is the indoor euro-cylinder retrofit, with Matter over Thread and the wider platform list, Bluetooth unlock and geolocation, while passcode and fingerprint need accessories and remote access is a one-time purchase. The two do not mount the same way. Pick the TP-Link Tapo DL100 to replace a sheltered deadbolt. Pick the Nuki Smart Lock Go to leave a European cylinder in place.

What the differences mean
How it attaches
The Nuki Smart Lock Go mounts inside, over a European cylinder, and you keep that key. The TP-Link Tapo DL100 replaces a deadbolt on a 54 mm or 38 mm bore. A rental with a euro cylinder is a Go problem. A house with a standard US deadbolt under a porch is a Tapo problem. Crossing them means returning one.
Keypad features
The TP-Link Tapo DL100 has the keypad built in, with anti-peep entry, one-time codes, a doorbell button and a lockout after repeated failures. The Nuki Smart Lock Go can add a passcode only with a keypad accessory, lists one-time and periodic codes the same way, and marks anti-peep and a doorbell as not supported. Fingerprint on the Go is another accessory. The Tapo has no fingerprint reader at all.
Weather
The TP-Link Tapo DL100 is IP54. Its write-up still says that is a sheltered doorway, not a wall in the rain, because water can reach the key cylinder. The Nuki Smart Lock Go is not weather rated and is described as an indoor retrofit. Sheltered US door: Tapo. Indoor euro cylinder: Go. Fully open weather is a weak case for both.
Platforms
The Nuki Smart Lock Go supports Apple Home, Google, Alexa, SmartThings, Home Assistant and Matter over Thread, with 2.4 GHz Wi-Fi and Bluetooth. Remote unlock is a one-time purchase. The TP-Link Tapo DL100 supports Alexa, Google and SmartThings on its own Wi-Fi and Bluetooth, and it marks Apple Home and Matter as not supported. Home Assistant on the Tapo is not documented. Battery life on the Go is not documented. The Tapo is rated about 10 months on 4 AA cells.
Which one to buy if
- you want a sheltered deadbolt with Wi-Fi and a doorbell
The TP-Link Tapo DL100 brings its own Wi-Fi, a keypad doorbell and IP54 sealing for a covered doorway.
- you must retrofit a euro cylinder
The Nuki Smart Lock Go mounts over that cylinder. The TP-Link Tapo DL100 is a deadbolt replacement and will not do that job.
- you need Apple Home to run the lock
The Nuki Smart Lock Go supports Apple Home and Matter. The TP-Link Tapo DL100 marks both as not supported.
- guest codes should work without an extra keypad
The TP-Link Tapo DL100 includes one-time codes and anti-peep entry on the lock. The Nuki Smart Lock Go needs a keypad accessory for codes.

What owners say
Owners are not arguing about the same hole in the door. Nuki Smart Lock Go owners like that nothing is drilled and that the lock meets them at the threshold with their hands full. The repeated worries are a motor that fails inside a year, cells that swell, and remote control that costs an extra purchase. TP-Link Tapo DL100 owners single out a timer that locks the house after the door closes, codes they hand to guests, and an install measured in minutes. They are the group that talks about water reaching the key cylinder on a fully exposed mount, and about notifications that sometimes do not arrive. Apple Home never comes up as a Tapo win, because it is not on the lock.
