Weatherables Keystone 2-Sided Key-Lockable Gate Latch - Secure Two-Way

In this review of the Weatherables Keystone 2-Sided Key-Lockable Gate Latch, the bottom line is straightforward: this latch is for homeowners and contractors who need a durable, two-way locking solution that works on vinyl, wood, and metal gates. It stands out because the keyed, self-latching design provides secure access from both sides while resisting rust and UV damage, making it especially useful where weather exposure and reliable lock operation matter.

Key Features

• Two-sided access: Allows opening from either side of a gate, which is useful for shared entry points or dual-access yards.
• Heavy duty construction: Made of UV-resistant nylon polymer and stainless steel so the latch resists rust and holds up outdoors.
• Lockable gravity latch: Self-latching action reduces jamming and the keyed lock adds security; keys are keyed alike for convenience.
• Easy installation: Kit includes instructions, a marking template, and fasteners, and fits square posts up to 5 in and gate gaps from 1/2 in to 1-3/4 in.
• Re-keyable option: Can be re-keyed to match a 5-pin house key for simplified key management across locks.
• Warranty support: Backed by a 1 million cycle warranty, which signals confidence in long-term durability.

Who It's For

The Keystone latch suits homeowners, landscapers, and fencing contractors who need a weather resistant, lockable latch for backyard gates, pool fences, pet enclosures, or shared alley gates. Its two-sided operation and ability to fit wood, vinyl, and metal gates make it versatile for most residential and light commercial applications.

Those who should look elsewhere include buyers needing a high-security deadbolt-style mechanism or specialized industrial locking hardware; the Keystone is a heavy duty, weatherproof latch but not a substitute for a multi-point commercial security lock.

Pros & Cons

Pros

Cons

• Not intended as a substitute for high-security commercial locks where maximum tamper resistance is required.
