The reach-through problem

A latch you can flip is a latch a hand can flip.

Plenty of windows lock with a small thumb-turn, which is fine until someone breaks a corner of glass and reaches in to flip it. There is no key, so the window opens for anyone who gets a finger to the catch.

A keyed lock takes that option away. The window can only be unlocked with the key in your pocket, so a hand through a broken pane finds nothing to turn.

If a hand can reach the lock, the lock should still need a key.

One key, two windows

Two locks, keyed alike, one key to keep track of.

The pair ships keyed alike, so the key that locks one bedroom window locks the other too. Keep it on a hook or in a drawer nearby, out of reach of the glass.

White, low-profile, and screwed to the frame, the locks sit quietly on the window until you need them. No wiring, no batteries, nothing to charge.

Screw it on, pocket the key.

1

Position it

Hold the lock and keeper where the two window frames meet.

2

Mark and drill

Mark the holes and pilot them for the included screws.

3

Screw it down

Fix both parts firmly to the frame.

4

Key it

Turn the key to lock the window shut, and keep the key handy but out of sight.

No app, no power, no monthly fee. A keyed mechanical lock that holds.
Renter-workable

A real keyed lock without a major change.

It fixes on with a few small screws that patch over easily, so it suits most rentals while giving you the keyed security a thumb-turn latch never could.

Layer your defense

A keyed window, and an alarm on the glass.

The lock keeps the window from opening without your key. The TremShield Alarm sticks to the same pane and sounds at 125dB the instant the glass is tapped or pried.

Good to know

Questions, answered calmly

It fits windows where two frames overlap at a rail, which covers most double-hung and sliding windows. The lock screws to one frame, the keeper to the other, and locked together the window cannot open.
A thumb-turn can be flipped by a hand reaching through broken glass. A key lock cannot be opened without the key, which closes that gap.
Yes, the two locks in the pack share a key, so you are not juggling separate keys for each window.
White, made to sit unobtrusively on a white window frame.
It mounts with a few small screws. The holes are minor and patch over easily if you move it later.

Pairs with this

Add the alarm layer.

A lock slows a break-in down. An alarm makes sure it never stays quiet: the TremShield Vibration Alarm senses the first vibration and answers with 125 dB, before a window ever gives. Peel-and-stick install, no Wi-Fi, no monthly fees.
