Why this product type matters
Managing guest access traditionally means key copies, lockboxes, or inconvenient meet-and-greets. Smart locks eliminate these hassles by letting you generate temporary codes or digital keys that expire automatically. For hosts on a budget, sub-$100 locks provide essential features like remote monitoring, entry logs, and flexible access without monthly fees. This means fewer late-night calls from locked-out guests, reduced security risks from lost keys, and a more professional, tech-forward experience that can earn better reviews. The ability to grant and revoke access instantly from your phone gives peace of mind whether you're hosting short-term rentals or family visitors.
How to choose
Prioritize WiFi connectivity over Bluetooth for true remote management—you'll want to create codes from anywhere without being near the lock. Look for models with dedicated guest modes that support multiple temporary PINs with customizable schedules. Battery life is critical; choose locks with 6+ month battery life and clear low-battery alerts to prevent guest lockouts. Check installation compatibility with your door thickness and existing deadbolt cutout—most fit standard doors but verify before buying. Consider BHMA Grade 3 certification for durability assurance. Avoid complex biometric-only systems for guests; keypad entry is most reliable. Finally, examine the app's guest management features: can you easily add/remove codes remotely? Does it keep entry logs? The eufy model leads in reviews/reliability, while Lockzo offers the best value with full WiFi features.

Frequently Asked Questions
What's the best access method for guests?
Keypad PIN codes work best for guests. They're simple to use, work without smartphones, and let you create temporary codes that expire automatically. Unlike fingerprint scanners that require enrolling each guest's biometrics, PINs can be shared via text or messaging apps before arrival. Look for locks that allow 20+ unique guest codes with time restrictions.
What happens if the battery dies while guests are staying?
Most smart locks have low-battery warnings weeks in advance. Battery life typically ranges from 6 months to a year. Keep spare batteries on-site and include this in your guest instructions. Some locks include emergency USB power ports or physical keys as backup. The eufy C30 emphasizes 'reliable power' with efficient battery management, while Lockzo includes traditional keys for emergencies.
Can I install these locks myself?
Yes, all four models feature DIY installation designed for standard doors. Most installs take 15-30 minutes using just a screwdriver. The eufy C30 specifically highlights easy installation. Check your door's thickness (typically needs to be compatible with 1-3/8 to 1-3/4 inches) and backset measurement before ordering. YouTube tutorials are available for each brand if you need visual guidance.
Are budget smart locks secure enough for rentals?
Yes. These locks use encryption similar to pricier models. The eufy C30 is BHMA Grade 3 certified for durability and security. All models provide automatic locking, incorrect code limits, and activity logs. For added security, change guest codes between stays and disable unused codes. Physical backup keys remain an option if digital systems fail. The key security advantage is eliminating unauthorized key copying and knowing exactly when guests enter/exit.
