Consider your door type: single-cylinder for viewing windows, double for no glass. Pair with a security bar like the SECURITYMAN Sliding Door Security Bar for patios. Test backset (2-3/8 or 2-3/4 inches). For RVs, try the LATCH.IT Black RV Door Lock.
Smart locks win for convenience: reduce lost keys by 70%, enable sharing codes remotely.
Enhance protection with these guides:
Grade 2 offers moderate security for homes, withstanding 800 lbs kick force and basic picking tests. Better than Grade 3, but below Grade 1 commercial standards.
It's okay for low-risk suburbs but poor against skilled thieves. Opt for smart upgrades like the Yale Assure Lock 2.
Very DIY: 15-20 minutes with screwdriver. Smart locks add 5-10 mins for wiring/apps.
Smart options like the Wyze Auto-Lock Bolt with fingerprints and auto-lock—far superior resistance.
Yes, but brass may corrode; choose weatherproof smart locks like Wyze (IPX5).
Most do for remote features; Yale and Philips have built-in Wi-Fi, no hub required.
