There are many types of window locks available on the market depending on the type of window, material, and level of security required. Some of the most common types of window locks include keyed locks, deadbolt locks, sliding window locks, casement window locks, sash window locks, double-hung window locks, and tilt and turn window locks. Each type of lock has its specific features and benefits.

Keyed window locks are one of the most popular types of window locks and have a mechanism whereby a key is used to unlock or lock the window. Deadbolt locks have a bolt that extends into a strike plate when locked, making it difficult for intruders to force it open. Sliding window locks are designed to keep sliding windows firmly in place, while casement window locks use a hook-shaped bolt to lock the window frame to the sill. Sash window locks are used to secure slide-in windows, while double-hung window locks have two locks that engage the sashes. Tilt and turn window locks are designed for inward opening windows and have a locking mechanism that controls the tilt and turn movement.
