How Changes in Temperature Affect Locks

Category : Blog , Locks

Many times, people consider the importance of locks when they’ve already stopped functioning the way they should. Often, one of the biggest perpetrators of lock problems is changing weather. Locks of all kinds can experience significant changes as the weather cools down or warms up, which can impact your security.

Vehicle locks, deadbolts, keypads and padlocks can face locking mechanism issues throughout the year, especially when extreme weather shows up. You might have difficulty opening the lock, the locking mechanism may fail or you may break your key during the turning process.

Hot Weather Changes

During the summer months, humidity and moisture can impact doors — even small changes can have a big impact on the function of your locks.


Businesses and homeowners often experience jams during the hotter months, often on exterior doors. For example, if you have a wood or plastic door, the material may warp or swell, which can impact the connecting lock. Swelling impacts lock alignment because the geometry of the frame and door change while the lock tries to stay in place. Deadbolts may be especially challenging to open if the door frame swells because they can get stuck in one position. These locks become compressed in these circumstances, making it difficult to move the lock at all.


Metal door locks can also face unique challenges in the summer. As the warm weather causes any lubricant to evaporate, the lock mechanism may get stuck as metal components expand. Although adding lubrication can reduce some lock issues, you won’t easily fix the problem if expansion occurs.

Cold Weather Changes

As temperatures begin to drop, you can also face some unpleasant lock issues.


For wood doors, the material may start to contract rather than swell. Although this process is the reverse of swelling, the outcome is the same — changes in the door and frame cause a lock misalignment. The results of this shrinking may also make it harder for the key to catch in the lock.


An additional problem you could face involves the freezing point of any lube you use on your locks. Although lubrication can make it easier to turn your locks, it stops being effective once it reaches the freezing point. If the lubricant freezes, or if any excess water freezes in the lock, the ice can prevent components from moving. Attempting to continue trying the lock in this state could result in structural damage or cause your key to break in the lock.

Additionally, your key may stick in the lock, or you may not be able to insert it at all if there is a lot of frozen buildup. Learning how to prevent locks from freezing is crucial for avoiding these issues.

Changes for Different Types of Locks

Many locks function in similar ways, but some can face unique challenges in different temperatures. Keep reading to discover when specific locks may be more susceptible to issues.

Car Locks

Vehicle locks can become very sensitive in the winter months. When temperatures drop to freezing and below, moisture inside the lock and mechanism can freeze. This issue can prevent you from inserting your car key or using your remote door opener.


You might notice your door locks sticking in the winter if any moisture enters them.

Common on garages, sheds and fences, padlocks face the biggest challenge when temperatures drop. You might notice your door locks sticking in the winter if any moisture enters them. The moisture in these locks can freeze, making them challenging or even impossible to open. Additionally, if you don’t use the space your padlock is protecting very often, it may face issues over time from a lack of preventative maintenance. For example, if you never lubricate the lock, the summer heat may cause additional problems for metal components, such as causing them to shrink or become brittle.


As keypads and other keyless locks grow in popularity, it’s essential to understand their unique issues. Many commercial spaces use keyless locks, which can impact business operations if they stop functioning. These locks don’t face the same problems as other lock types. Instead, they face mechanical issues, push button jams and battery drain problems.

While most all-weather locks will function in any weather condition, they may face issues under extreme pressure. This type of pressure can lead to mechanical issues that may prevent the mechanism from working. Additionally, cold weather can affect keyless entry. Prolonged exposure to extremely cold temperatures can lead to shorter battery life spans. Typically, these batteries can last up to a year or longer in normal conditions, but a harsh winter can chop this timeline severely. If the battery dies and you don’t have a backup to get it running again, you might be stuck outside.


When functioning normally, deadbolt lock mechanisms retract when you place and twist your keys inside. Alternatively, the mechanism extends when you lock it. As we mentioned above, you may notice difficulties in the summer months if your door warps or swells, causing a misalignment of the components that extend and retract the bolt.

Best Practices for Reducing Weather Impacts

Regardless of the type of locks you use, there are several tips you can keep in mind to ensure their longevity and your safety and convenience. Check out these best practices:

  • Consider replacing plastic or wood doors with more durable and resistant options.
  • Create and follow a routine maintenance schedule, such as adding lubrication.
  • Keep your locks as dry as possible by using overhanging or protective coverings to keep snow and moisture out and prevent door swelling in the summer.
  •  Warm your key with your hands before inserting it into a lock in the winter.
  • Hire a reliable and professional locksmith when installing new locks or addressing a lock concern.

Top 10 Reasons to Replace Your Door Locks

Category : Locks

With so many issues to be concerned with in daily life, the last thing you need to worry about is your home security being threatened by inferior or compromised locks. Strong, quality locks on your front and back doors give you confidence. That’s not just when you’re away. It’s also when you’re relaxing inside, taking a shower or sleeping.

Locks are your last line of defense in protection from burglars or unauthorized intruders. Home burglaries are common throughout the United States, and it’s not always a total stranger that sneaks into your house. Unlawful entry can well be from someone you know. That could be a previous tenant, an ex-roommate or even a separated significant other.

Preventing illegal entries is your first step in a proactive approach to home security. The best security systems rely on a layered approach that integrates several devices. Good exterior lighting and clear visibility are a few of these. Motion-activated sensors are another excellent security tool. But nothing beats the value of good quality locks where you have proper key and access control.
