What the differences mean

Ways to unlock

The Eufy Smart Lock C220 adds a fingerprint reader on top of the keypad, app and key, which the Eufy Smart Lock C34 does not have. If you want to open the door with a finger rather than a code, only one of these offers it.

Ecosystem support

The Eufy Smart Lock C34 reaches Apple HomeKit, SmartThings and Matter over Thread as well as Alexa, Google Home and Home Assistant. The Eufy Smart Lock C220 stops at Alexa, Google Home and Home Assistant, so Apple and Matter homes need the C34.

Warranty

The Eufy Smart Lock C34 carries an 18-month warranty against one year on the Eufy Smart Lock C220, which is a straight win if the lock is your only way in.

Battery and backup

Both run on eight AA batteries rated around eight months. The Eufy Smart Lock C220 adds a USB emergency port so a battery bank can power it if the cells die, while the Eufy Smart Lock C34 has no backup battery input and relies on you watching the level.

One-time codes

The Eufy Smart Lock C34 supports one-time passwords for guests or deliveries. The Eufy Smart Lock C220 supports scheduled and periodic codes but not a true one-time code, so a temporary visitor is better served by the C34.

What owners say

Both locks win the same compliment: an easy swap of a standard deadbolt that takes minutes with a screwdriver and no hub. The difference is what owners reach for. Eufy Smart Lock C220 owners lean on the fingerprint reader, which most describe as fast and reliable even with damp or cold hands, and they praise the dependable auto-lock and the eufy app's alerts when the door did not fully shut, with a few reporting a print that never took for one member of the house. Eufy Smart Lock C34 owners like the quiet, smooth motor and the responsive touchscreen keypad, and several come from older locks that ate batteries or never worked; their warnings are a low-battery alert that can stay silent until the cells are dead, no backup battery port, and auto-lock that does not confirm the door is shut.

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.
