When paired with TCL’s advanced smart lock products—such as the D2 Pro Palm Vein Door Lock and the D2 Plus Fingerprint Door Lock—home security becomes more intelligent, efficient, and stylish than ever before.

This in-depth guide explores what Smart Lock by Google Assistant is, how it works, why TCL’s solutions are at the forefront of this technology, and how to make the most of these innovations.

Smart Lock by Google Assistant is a feature that enables you to control compatible smart locks through voice commands, smartphone apps, and integrated smart home devices. It transforms locking and unlocking from a manual task into an automated, hands-free experience.

Whether you’re telling your Google Nest Hub, “Hey Google, lock the door,” or checking lock status while on vacation, this integration offers unmatched convenience and peace of mind.

With TCL’s premium smart locks, the experience goes a step further—bringing cutting-edge biometric authentication, robust design, and multiple access methods together in a single device.

The operation of Smart Lock by Google Assistant relies on three essential components:

You need a smart lock compatible with Google Assistant, such as the TCL D2 Pro or D2 Plus.
