Window Locks & Latches

Match the lock style to your window type (sliding, double-hung, casement, or awning), check mounting options (screw-on, clamp, or adhesive), and prioritize material (stainless steel or zinc alloy) for durability and security

Look for tamper-resistant designs, keyed or multi-point locking for higher security, reinforced mounting plates or longer screws for stronger attachment, and childproof or limited-open options if safety is a concern

Window locks and latches are available across price tiers; basic styles and single locks are commonly found under $50, while more robust or keyed/multi-point systems typically cost more; expect average prices in the low tens to low hundreds depending on features

Measure the window sash thickness, the distance between the mounting screw holes or the gap where a latch will sit, and the clearance between moving parts; compare these dimensions to the product specifications before buying

Many window locks are designed for DIY installation using basic tools (screwdriver, drill, measuring tape), but complex multi-point systems, metal frames, or installations requiring precise alignment might benefit from professional installation

Stainless steel and coated zinc alloys resist corrosion and are better for humid or coastal environments; painted or powder-coated finishes reduce rust on metal frames, while solid brass offers good durability for interior use

Keep moving parts clean and free of debris, lubricate hinges and locking mechanisms periodically with a dry lubricant or silicone spray, and tighten or replace worn screws and fasteners as needed
