How Cold Weather Affects Your Door Locks, Anchorage, Alaska

Extreme temperatures during winter can really impact the functionality of your home’s exterior door locks. Moisture can infiltrate locks and cause it to freeze, causing your locks to jam.

A Locksmith Guide to Frozen Door Locks

How Do Locks Freeze?

Few things are more annoying than dealing with frozen locks that make it hard to open your door. Once temperatures drop below freezing any moisture inside the lock mechanism can turn to ice and make it difficult to move. Another issue is when cold weather causes locks to contract which causes the key to become incompatible and won’t allow you to open the door.

How You Can Unthaw Door Locks

There are simple ways to de-thaw locks, so you can safely insert your keys. The first trick is to use a hair dryer on the warm setting which will melt any ice inside the lock. You can also use a heating pad or any warm object that will provide enough heat to remedy the problem. A locksmith also has heating tools and may be able to better address the situation moving forward. You can prevent locks from freezing by keeping them lubricated with oil and keeping water out of the lock when possible.
