Are Keyless Locks Affected By Weather Conditions? Locks are typically an afterthought until they malfunction, catapulting them to the forefront of our concerns. It's in these moments that the pivotal role of a reliable lock becomes glaringly apparent.

Problems with Traditional Locks in Canada:

  • Summer Issues:

    • Rising temperatures cause door frames to expand.

    • Expansion leads to pressure on deadbolt locks, causing jams.

  • Winter Challenges:

    • Cold weather causes door frames to contract.

    • Contraction can lead to misalignment between locks and doors, making locking/unlocking difficult or impossible.

Surprisingly, weather changes are often the unseen adversary of lock performance. In the heat of summer, escalating temperatures can lead to the expansion or swelling of door frames. This expansion exerts pressure on deadbolt locks, sometimes causing them to jam.

Conversely, the grip of winter can result in door frames contracting, potentially leading to a misalignment between the lock and the door. This misalignment can make the door challenging to lock and, in severe cases, render locking or unlocking impossible.
