How to Keep an Outdoor Padlock from Freezing?

Frozen outdoor padlocks are one of the most annoying things in winter life. This may delay many things. Fortunately, this can be avoided, and there are many simple ways.

1. Choose a more resilient lock

The easiest way to prevent locks from freezing is to choose the correct lock. Typically, high-security outdoor padlocks use a ball-bearing locking system rather than a spring-loaded bar. This means fewer moving parts are used in the lock, so it’s less likely to freeze together.

Then there is the choice of a waterproof lock. Because waterproofing usually means a better seal, excess water doesn’t get into the lock body, preventing freezing.

2. Prevent freezing

If you’ve already bought your locks and don’t plan to replace them, there are a few things you can do to keep your outdoor padlocks from freezing.


You need to send the nozzle directly to the lock to ensure that the lubricant can be sprayed well. Because the lubricant can prevent water from entering the lock cylinder. In winter, you can spray 1-2 times a week to keep it in good working order. Also, apply lubricant before a cold snap or blizzard.

Graphite spray can also play the same role as lubricants. But graphite spray has no pungent odor and is better than lubricant.

Compressed air can

Unlike the methods mentioned above, a can of compressed air can blow moisture out of the lock cylinder. With the moisture blown out, the lock will be less likely to freeze or get stuck. But this is obviously only a short-term solution, as this does not prevent moisture from entering the lock cylinder.

Petroleum jelly

Petroleum jelly needs to be smeared on the key and the key should be shaken a little when inserted into the lock to make sure it covers the inside. Doing this also ensures that there is no moisture inside the lock, which will prevent it from freezing.

Covering the keyhole with a strong magnet will keep moisture from sneaking in. When you’re ready to unlock the lock, just remove the magnet and open the lock as you normally would.

Package the outdoor padlock

Items that wrap padlocks can be thick socks or glasses bags. Although this method cannot keep warm, it can prevent moisture.

3. What should I do if it freezes?

If the lock is already frozen, we really have a hard time opening it quickly. Try using hand sanitizer. Put it on the key and then slid it into the lock hole. Shake the key back and forth a few times during the unlocking process and try to turn it. The alcohol in hand sanitizer will melt ice.

If you don’t have any tools handy, you can also use the heat of your hands to melt the ice, which usually takes 5-15 minutes, depending on how much ice is available.
You can choose to buy a lock de-icing spray, which is a bit more expensive but works better.
