Frequently Asked Questions

Do these smart deadbolts fit standard US exterior doors without extra drilling?

Yes, these smart locks are engineered to replace standard deadbolts on residential doors without drilling extra holes. Most models fit doors with standard boreholes up to 54 mm and work with common backset measurements of 2-3/8 inches or 2-3/4 inches. Installation typically requires only a basic screwdriver and takes about 15 minutes for most standard setups.

What happens if the smart lock batteries die completely while you are locked outside?

You can still gain entry using the included physical backup keys or an external emergency power source. Depending on the model, the exterior assembly includes a USB-C emergency port or hidden keyway that lets you power the lock temporarily with a portable power bank. This fail-safe hardware design ensures you never get stranded outside during an unexpected battery outage.

Does the best iulock eufy smart lock require an external Wi-Fi bridge to enable remote access?

No, models in this lineup feature built-in Wi-Fi modules that connect directly to your home network without an external plug-in bridge. You can lock or unlock your door, issue guest credentials, and review entry logs remotely via the mobile app. For video-enabled models, you can monitor front-porch footage locally without recurring cloud fees, similar to standalone video doorbells without subscriptions.

How reliable is the biometric fingerprint scanner in cold or rainy weather?

The self-learning biometric scanners operate reliably across broad temperature ranges from -22°F to 158°F with IP53 or IP65 weather ratings. Built-in artificial intelligence refines fingerprint recognition with every successful scan to reduce false rejections over time. Wiping moisture or dirt off the sensor surface helps maintain the rapid sub-second unlocking speed during inclement weather.

Can you integrate these smart locks with smart home voice assistants and automations?

Yes, these locks support voice commands and automations through Amazon Alexa and Google Assistant. Certain premium models also include Matter support for broader ecosystem integration with Apple Home and SmartThings. This allows you to check entry status and include your lock in daily departure routines effortlessly.

Can you create temporary access codes for rental guests, cleaners, or contractors?

Yes, the companion security app allows homeowners to configure custom PIN codes with specific schedules or expiration windows. You can grant temporary access to house cleaners, dog walkers, or vacation guests without sharing permanent entry credentials. The system records an event history log so you always know exactly when a visitor used their scheduled code.
