How to Choose
Selecting the best smart lock for your front door involves comparing several key specifications. Below is a buying guide to help you understand what matters, followed by a comparison table of the five picks.
Connectivity
Smart locks connect either through built-in WiFi or require a separate hub or bridge. WiFi-enabled locks like the Philips 4200 Series, eufy C220, and Schlage Encode can be controlled directly from your home network without extra hardware. The Veise VE017 uses the KK Home App over WiFi but needs a G1 Gateway for voice control. The TEEHO TE001 has no WiFi and is controlled only via the keypad. Check whether your home’s WiFi is 2.4GHz or 5GHz; many smart locks specify 2.4GHz compatibility.
Unlock Methods
Consider how you and your family prefer to enter. Fingerprint readers are fast and convenient – the Philips 4200 Series claims 0.3 seconds, the Veise VE017 claims under 0.2 seconds. All five accept keypad codes. Voice control through Alexa or Google Assistant is available on the Philips, eufy, and Schlage (Veise requires an additional gateway). The TEEHO TE001 uses only codes and a physical key. For those who want to grant temporary access, look for one-time or recurring codes, which the Philips, Veise, and TEEHO provide.
Battery Life
Battery life depends on usage and the number of batteries. The Veise VE017 and TEEHO TE001 use 4 AA batteries, with Veise claiming 12 months and TEEHO up to 365 days. The eufy C220 uses 8 AA batteries and claims about 8 months. The Philips 4200 Series and Schlage Encode do not list battery type or expected life in their listings. The TEEHO and Veise list low-battery indicators, and the Veise has a USB-C emergency power port.
Security Features
Look for features like alarm systems, tamper alerts, and certification. The Schlage Encode has a built-in alarm for forced entry and the highest BHMA residential rating. The Veise VE017 stores data locally with AES128 encryption and includes anti-peeping code protection. The TEEHO TE001 has IP54 weather resistance and anti-peeping protection. The Philips and eufy do not list security certifications in their listings, but they include app-based alerts and status checks.
Installation
Most smart locks are designed to fit standard door preparations. The Schlage Encode fits doors 1-3/8 to 1-3/4 inches thick with backsets 2-3/8 or 2-3/4 inches. The TEEHO TE001 requires a 2-1/8-inch (54mm) bore and does not fit 38mm holes. The eufy C220 fits bores under 54mm with a removable spacer. The Philips and Veise listings do not give door dimensions. All models claim installation with basic tools, usually a screwdriver. For detailed guidance, see our How to Install a Smart Lock guide.

Yes, if the lock has built-in WiFi or works with an app through a hub. The Philips, eufy, Veise, and Schlage models all offer remote control via their respective apps (Philips Home Access, eufy Security, KK Home, Schlage Home). The TEEHO TE001 does not offer app-based remote control.

The eufy C220 claims approximately 8 months on 8 AA batteries. Battery life for the Philips and Schlage models is not listed. Check each listing for low-battery alerts.
