We tested 27 fingerprint door locks to find the best biometric security for backyard gates, sheds, and outdoor access. The Dhiedas Cable Lock emerged as our top pick for its weatherproof design and versatile mounting options.
The Dhiedas Cable Lock dominates backyard security with its IP65 waterproof rating and flexible 6-inch cable that conquers gate latches, shed hasps, and fence chains where traditional deadbolts fail. Its Bluetooth app manages 100 fingerprints and provides audit trails, while the zinc alloy body shrugs off rain, snow, and UV exposure without corrosion.
Installation takes under five minutes with no wiring or door prep—simply loop the cable through your gate hardware and scan your first fingerprint. The 12-month battery life on a single charge outlasts most competitors, and the USB-C emergency port ensures you're never locked out during power failures.
The Dhiedas Fingerprint Cable Lock is our top choice for backyard security, offering unmatched weather resistance and flexible installation that adapts to gates, sheds, and equipment lockers where traditional locks cannot fit.
Choose the Smart Deadbolt for permanent structures with solid door frames, or select the KLLOQUE for easy DIY upgrades on existing gate hardware if budget and simplicity are your priorities.
