1. White vinegar

In this method, you need to mix white vinegar with room temperature plain water in a ratio of 3:1. This method helps reduce the concentration of vinegar and hence minor damage to your locks.

To remove the ice layer, put the mixture of white vinegar and water in a spray bottle and spray it directly on the lock to act like a de-icer.

2. Place a magnet over the lock

Placing a magnet over the keyhole is a simple way to prevent your lock from freezing. Most magnets will work as long as it is large enough to cover the keyhole fully.

Then, all you need to do is cover the magnet over the lock when you leave. Then, after you get in, simply put the magnet in your pocket or purse for later use.

3. Sanitize your key

Hand sanitizers have a high alcohol content, which prevents them from freezing and enables them to thaw the ice. Spray a little bit of the gel on your key, make sure it covers both sides well, and it should unlock your stuck door lock after a few attempts.

4. Using a hairdryer 

Using a hairdryer, let the warm air reach inside the lock mechanism and you can unfreeze your door lock without the help of a professional. Then, utilize it directly in the frozen lock for a few minutes. Then, heat your key before putting it inside.

You may also use a toilet paper tube and put it between the hairdryer and frozen lock to pass the heat to the lock for faster-melting action and you can unfreeze your door lock easily.

5. De-ice Method

Now you can unfreeze your door lock in a few simple steps like a commercial de-icing fluid dissolves ice and stops moisture that causes further ice build-up. Any hardware store or auto shop will carry this spray-on product.

If you do not have to de-ice on hand, try rubbing alcohol, diluted white vinegar, or wiper fluid in its place.
