Buying Guide: Key Purchase Considerations

  • Door type and compatibility: Confirm whether your doors are outward- or inward-swinging, with knob or lever hardware, and check the spacing between handles to ensure a secure fit.
  • Material and durability: Look for metal constructions (die-cast aluminum, zinc alloy) over plastic for better load-bearing capacity and resistance to tampering.
  • Locking mechanism: Decide between keyed entry, non-keyed internal locks, or combination devices. Consider whether you want a portable, no-drill installation or a more permanent fix.
  • Security level vs. convenience: A heavier barricade-style device offers stronger security but may be less convenient for daily access. A balance between protection and ease of use is ideal for homes with kids or frequent entry points.
  • Installation: Some products require no tools or drilling, while others may need standard hardware installations. Check compatibility with door thickness and existing hardware.
  • Indoor vs. outdoor use: For added weather resistance, selecting products designed for outdoor use may be beneficial, especially on exterior French doors.
  • Aesthetics: Matte, satin, or powder-coated finishes help the lockset blend with door hardware, maintaining curb appeal while improving security.
  • Keys and accessibility: Consider how many keys are included, the ability to rekey, and whether the device allows key access from inside and outside as needed for your security plan.

When choosing a locking solution for French doors, assess how often doors are used, the risk of unauthorized entry, and whether you prefer a non-permanent solution. A combination of a durable main lock plus a secondary security device can provide layered protection without compromising daily usability.
