Winter weather can cause problems around your home especially when cold temperatures and moisture affect outside door locks. A frozen lock can make it hard to get into your home, your office or your car when you really need to. Learning how to prevent door locks from freezing can save time, cut down on frustration and help keep your property safe. Luckily a few simple habits can keep locks working during cold weather. From using the oil to keeping locks away from snow and water these seven easy tips can help you get ready for winter.
Why Do Door Locks Freeze in Winter?
Door locks usually freeze when water gets into the lock cylinder or the parts around it and turns into ice when temperatures drop. Water can come in from rain, melting snow, condensation or damp air. When the temperature goes below freezing this water can stop the parts from working right.
Exterior locks are especially at risk because they are directly in the weather. Bad weather strips, broken covers and old door parts can make the problem worse. Cold temperatures can also affect the metal parts inside a lock making a mechanism even harder to use. Keeping things maintained and protected from moisture can lower these risks and help locks work all through winter.
7 Good Ways to Stop Door Locks from Freezing
Taking steps before the cold weather arrives can help you avoid lock problems. The following ideas are helpful for people who own homes or businesses getting ready for weather.
Apply a Lock-Safe Lubricant Often
Using the oil helps the parts inside the lock move smoothly and lowers friction. Choose a lubricant that is made for door locks like a PTFE or graphite product that the lock maker says is good.
Put the oil on as the instructions say of using too much. Don’t use oils from your kitchen because they can bring in dust and dirt making the lock harder to use later. Oiling before winter starts can keep the lock working and lowers the wear on the inside parts.
Keep Water and Snow away from Locks
Water is a reason why outside locks freeze. After snow or freezing rain clear away the snow and ice near the doors and the lock parts. Use a dry cloth to wipe away water from the parts that are out in the open. Make sure rainwater does not gather near the door frame or fall directly on the lock.
Keeping the area around the entrance dry lowers the chance that water gets into the lock and freezes during the night.
Put Weather Protection Around Outside Locks
Weather protection can help stop rain melting snow and wind from getting to locks. Think about putting up a door cover, trim or a weatherproof lock shield. Examine the state of the door seals you currently have. Make sure they are in good shape. Water and chilly air may enter close to the entrance due to broken seals. A protected entrance helps cut down on direct exposure to harsh winter weather and helps the whole door system stay in good shape.
Use a Lock Cover in Very Cold Weather
A lock cover adds another layer of protection against snow, rain and freezing water. Covers are available for types of outside locks and can be very helpful for doors that get a lot of wind. Choose a cover that fits tight without stopping the key from working. Make sure it is made from weather- material and is easy to open when needed. This small addition can lower the amount of moisture that reaches your lock when the weather is very bad.
Keep Keys in a Safe Easy Place
Having an extra key can be helpful if your main key is hard to use because of the cold. Keep another key with a trusted person or in an easy place. Don’t leave keys outside under doormats, flower pots or other places that are easy to see. These spots can be a security risk. For homes with smart locks check the battery levels before winter. Cold weather can affect how batteries work depending on the device and its rules.
Get a Professional to Check Your Locks Before Winter
A professional locksmith can look at the locks before the cold weather comes. During a check the expert might look at the lock cylinder, inside parts how the door lines up and signs of rust or wear. If a lock is already stiff or hard to turn, fixing it early can stop problems from happening in winter. Regular checkups are especially good, for buildings, business entrances and doors that are used a lot. A maintained lock system is more likely to work when it gets cold.
