Living in Minneapolis comes with a challenge of dealing with freezing temperatures and during these periods your door locks and car locks do not seem to works like they do in warmer weather.
Extreme cold weather can have an impact on locks and freezing temperatures cause all metal parts within the locks to contract which can lead to misalignment of the lock and difficulties inserting or turn the key.
Frozen Locks
Moisture inside the lock can freeze in minus temperatures making it difficult and even impossible to turn the key. Cover the lock with a magnetic cover to keep moisture out and spraying graphite based lubricants can help to prevent the locks from freezing.
Contracting Metal
Metal contracts in cold temperatures and can cause misalignment between the lock and the key making it hard to unlock or lock the door. Regularly check the alignment of the lock and door frame and if necessary make adjustments to ensure proper fit.
Slow Locks
The cold can make the internal parts inside the lock get stiff which can make turning the key difficult. Again lubricate the locks with graphite based lubricants before winter begins.
Broken Keys
Because of the resistance caused by frozen locks there is a higher chance the key will break off inside the lock. Avoid pushing in the key in to a frozen lock and try to heat it up before.
Problems With Electronic Locks
The most common issue with electronic locks is dead batteries. Cold weather can drain batteries faster so if you replace them regularly you should not have any problems.
Lubrication Issues
Oiled based lubricants can get thicken in cold weather and might disturb the smooth operation of the lock. Instead you can use graphite based lubricants because they are less likely to have this problem.
