Sliding Window Locks 12 Pack with Key - Silver Adjustable Security

Our review of these sliding window locks finds them best for homeowners and renters who need an affordable, no-drill way to secure sliding windows and doors. The biggest reason to buy is the combination of a simple 3-step install and an upgraded two-hole fixing design that adds holding power on deeper tracks. Installation is quick with the included hex keys and gaskets, and the single vertical key lets the owner apply locks at the middle track for controlled partial opening - a practical choice for families with children or pets.

Key Features

• Track fit guidance: Clear track size requirements ensure buyers check compatibility before ordering so the locks will fit properly on compatible sliding and vertical windows.
• Upgrade protection design: Two fixing holes per lock and protection pads increase holding power and prevent scratches to window tracks.
• Included keys and tools: The set ships with one vertical key and 12 hex keys so every lock can be adjusted and reused without extra purchases.
• Wide safety use: Locks allow partial opening to reduce the risk of falls for children and pets while still permitting ventilation.
• Easy installation: A three-step, no-drill installation keeps the process fast and reversible for renters or seasonal repositioning.

Who It's For

This pack is ideal for families, landlords, and office managers who need multiple locks at once and want to secure sliding windows, patio doors, and vertical sliders without drilling. The included gaskets and hex keys make it simple to fit and re-fit across many openings.

Those with very narrow or unusually tall tracks should check measurements before buying; the locks require track height greater than 0.48in and width less than 0.61in, so if a track falls outside that range another solution is necessary.

Pros & Cons

Pros

• Easy to install with no drilling and all necessary hex keys included.
• Sturdy, well-made feel with double-hole fixing for improved holding power.
• Protection pads prevent scratches and improve stability on window tracks.
• Good value for a 12-pack intended for multiple rooms or properties.

Cons

• Requires specific track dimensions so it will not fit every sliding window or door.
• Single vertical key is useful but sharing or replacement could be inconvenient if lost.
