Updated October 2026
Data from Amazon and official Philips and TP-Link sites.

The Philips 4200 Series Smart Deadbolt with Door Lever answers with the fingerprint reader and a matching lever handle in the same box, which the Tapo has no equivalent for. Both connect straight to 2.4 GHz Wi-Fi and Bluetooth, work with Alexa and Google Home, and skip Apple Home and Matter. Choose the TP-Link Tapo DL100 for the cheaper, longer-lasting lock with an IP54 exterior, and the Philips 4200 Series Smart Deadbolt with Door Lever if fingerprint entry and a matching handle set matter more than the eight AA cells it eats.

What the differences mean

Batteries

The Philips 4200 Series Smart Deadbolt with Door Lever runs on 8x AA cells rated for 6 months, and owners often see the warning sooner. The TP-Link Tapo DL100 uses 4x AA and is rated for 10 months, plus a USB-C emergency port if the cells die.

Fingerprint reader

Only the Philips 4200 Series Smart Deadbolt with Door Lever has one. The TP-Link Tapo DL100 relies on the keypad, the app and its two keys, which is fine unless you want to walk in with a fingertip.

Weather resistance

The TP-Link Tapo DL100 is listed at IP54, a rating for a sheltered doorway, and owners warn about water reaching the key cylinder on exposed doors. The Philips is listed as weather resistant without a rating, so neither should be treated as a fully exposed outdoor lock.

Doorbell button

The TP-Link Tapo DL100 has a doorbell ring button on its keypad, so it can announce visitors. The Philips 4200 Series Smart Deadbolt with Door Lever has none.

Smart home platforms

Both work with Alexa and Google Home and neither supports Apple Home or Matter. The TP-Link Tapo DL100 adds SmartThings, while the Philips 4200 Series Smart Deadbolt with Door Lever lists Home Assistant, through a community integration.

Which one to buy if

What owners say

Owners of both locks talk about the same daily wins: a keypad that makes codes for family and guests painless, an app with an activity log, and installation that takes an evening. On the complaints side, batteries and Wi-Fi come up for both. Philips 4200 Series Smart Deadbolt with Door Lever owners love the fast fingerprint reader and how the matte finish and matching lever make the door look deliberate, but many see the low-battery warning weeks after fitting the eight AA cells, some report the lock dropping off the network and a few hit jam warnings. TP-Link Tapo DL100 owners single out the auto-lock timer and the Tapo app, and warn that battery life falls short of the headline figure with Wi-Fi on, that notifications can drop and that the IP54 rating is for a sheltered door.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
