Start with where you’ll use the lock, then match features to your needs.

• Use case: Door deadbolts/knobs are great for front doors; biometric padlocks fit lockers, gates, or backpacks.
• Weather: For outdoor use, look for an IP rating (e.g., IP54–IP66) that indicates dust/water resistance.
• Access methods: Fingerprint plus keypad, physical key, or app control can add flexibility.
• Connectivity: Built-in Wi‑Fi enables remote control; Bluetooth supports local app access.
• Capacity: Some models store dozens to hundreds of fingerprints or passcodes.
• Power: Check battery type, life, and any USB emergency power options.
• Fit & install: Verify door measurements and hardware compatibility.

Product pages on Walmart.com list specs and filters to help narrow to waterproof, Wi‑Fi, or keypad options.

Many smart deadbolts and keyless entry door knobs are designed to replace existing hardware using the standard pre‑drilled holes on most doors.

1. Remove your old deadbolt or knob and keep the latch/strike area visible.
2. Align the new lock’s latch and secure the exterior and interior assemblies per the instructions.
3. Install batteries, set the auto‑lock if desired, and enroll fingerprints/passcodes.

To help avoid drilling, check your door’s measurements (bore hole size, backset, and thickness) against the product specs on Walmart.com. If your door isn’t prepped or measurements are non‑standard, drilling or an adapter may be needed. When in doubt, a professional installer can help reduce the risk of damage.

Outdoor readiness depends on the lock’s weather rating and construction.

• IP rating: Look for an IP54–IP66 label for dust and water resistance; higher numbers generally indicate more protection.
• Materials: Some padlocks use stainless housings and sealed electronics designed to resist corrosion and moisture.
• Placement: If possible, mount door locks under a cover and avoid direct spray.
• Maintenance: Keep the fingerprint sensor clean and dry for reliable recognition, especially in heavy rain.
• Cold weather: Battery performance can vary in low temperatures; recharging or replacing batteries periodically may help.

Check each product’s specs on Walmart.com to confirm outdoor suitability and care recommendations.

There are several ways to regain access, depending on the model.

• Backup key: Some door locks include a traditional key cylinder. Keep a spare key in a safe place.
• Keypad codes: Many offer passcodes that work even if the fingerprint sensor isn’t available.
• Emergency power: Certain locks have USB or Type‑C ports for temporary power from a power bank.
• Alerts: Apps often provide low‑battery notifications, which can help you recharge or replace batteries before they’re depleted.
• Routine checks: Test backups occasionally to confirm they’re working.

Features vary, so review the product page and manual on Walmart.com for the specific backup options your lock supports.

Most fingerprint locks support multiple users and flexible access controls.

• Fingerprints: Enroll individual fingerprints for family members; many models store numerous profiles.
• Passcodes: Create standard or temporary PINs; some support one‑time codes and anti‑peeking password entry.
• App control: With Bluetooth or Wi‑Fi, you can add/remove users and adjust settings from your phone, and some models allow remote control.
• Best practices: Name user profiles, keep master codes private, and remove access after visits.

Exact steps differ by device, so check the setup guide on the product page. Planning access ahead of time helps balance convenience with security for your smart lock or biometric padlock.
