Your padlock will not open with a key? There might be several reasons for this such as:
– You do not use the correct key for this padlock. Sounds crazy but does happen.
– It is freezing. Freezing temperatures might lead to a frozen padlock and in this case the moveable parts in the padlock will not move and thus the key will not open the padlock. You can solve this by putting the padlock into warm water for a while. This should unfreeze the padlock and should allow to open it again. Of course this will work only if your padlock is close to your house / apartment. If this is not the case, you can try car- anti freeze sprays. You will have to wait a while and have to repeat the whole procedure of spraying the anti-freeze into the padlock but at some point it will open.
For reducing the risk of a freezing lock we recommend to use lubricants which have a freezing temperature below water.
– You are not in a freezing area but you have dust or / and humidity. Moisture in the padlock can cause that the inner parts of the padlock rust. In this case they will stick and will not work as freely anymore. Same thing applies for dust in the padlock. If this happens, you can use a machine oil (silicone or Teflon bases lubricant) which you have to apply for the keyhole and the space around the area where the shackle goes into the padlock. Try to push the shackle a bit more into the padlock and try to insert they key into the keyhole. This combination of motion and lubricant should help to unstick the inner parts of the padlock. If this still does not work very well, try to soak the padlock in the lubricant.
