Data from the official Nuki and TP-Link sites.
2026 verdict
On a standard deadbolt door where a keypad is wanted, the TP-Link Tapo DL100 beats the Nuki Smart Lock Pro, cheaper and better reviewed.
Its backlit keypad brings one-time guest codes, anti-peep entry and a doorbell button, it is rated for 10 months on four AA cells against 6, and its exterior is IP54. The Nuki Smart Lock Pro wins on connectivity and platforms: built-in Wi-Fi and Bluetooth, Matter over Thread with Apple Home, Google, Alexa, SmartThings and Home Assistant, and hands-free auto-unlock as you approach. The two are made for different doors, since the Nuki is a retrofit over a European cylinder and the Tapo a deadbolt for standard bores. Choose the TP-Link Tapo DL100 for a budget keypad deadbolt, and the Nuki Smart Lock Pro for a European door in a Matter or Apple home.

What the differences mean
Door type
The Nuki Smart Lock Pro retrofits over a European cylinder from the inside, which requires the cylinder to protrude slightly. The TP-Link Tapo DL100 replaces a deadbolt in a standard 54 mm or 38 mm bore. The door you have settles most of this comparison.
Smart home platforms
The Nuki Smart Lock Pro works with Apple Home, Google Home, Alexa, SmartThings and Home Assistant through Matter over Thread. The TP-Link Tapo DL100 works with Alexa, Google Home and SmartThings, without HomeKit or Matter.
Keypad
The TP-Link Tapo DL100 has its keypad on the door, with guest codes, anti-peep entry and a doorbell button. The Nuki Smart Lock Pro needs Nuki's keypad accessory for codes and fingerprints.
Power
The TP-Link Tapo DL100 runs on four AA cells rated for 10 months, with a USB-C emergency port. The Nuki Smart Lock Pro has a rechargeable built-in battery rated for 6 months and no backup.
Which one to buy if
- your door has a European cylinder
The Nuki Smart Lock Pro fits over it without changing the lock.
- your home runs on Apple Home
The Nuki Smart Lock Pro supports HomeKit and Matter; the TP-Link Tapo DL100 does neither.
- guests need a code on the door
The TP-Link Tapo DL100 has a built-in keypad with one-time codes, with no accessory to buy.
- you want the lowest cost
The TP-Link Tapo DL100 is the cheaper lock, and the Nuki gets pricier once its keypad is added.

What owners say
Owners of both locks find installation quick and lean on auto-lock every day. Nuki Smart Lock Pro owners single out built-in Wi-Fi that the cheaper Go charged extra for, a strong and fast motor, hands-free unlocking with full hands and a premium build, and their complaints are the price once the keypad is added, a battery that stopped charging for one owner and install requirements for the cylinder. TP-Link Tapo DL100 owners talk about a set-and-forget auto-lock timer, per-person codes with an activity log and a solid metal exterior, while they warn that water reached the key cylinder on exposed doors, that battery life drops with Wi-Fi on all day and that notifications sometimes drop.
