One: Why can't I open the lock with a key?
If the key for a mortise lock does not work, it is likely that the lock's internal mechanism is blocked by foreign objects or has rusted, which prevents the key from opening the lock.
Two. What should I do if the key for the lock cannot be used?
1. First, you need to acquire some lubricating oil. Common oils, vegetable oil, kerosene, or rust removers can be used.
2. Then, use a cannula to introduce oil into the lock mechanism.
3. Then, apply a small amount of lubricant to the key.
4. Then, insert the key into the keyhole and gently turn it left and right. Now, check if the lock is easy to use.
5. If the above methods do not work, try using putty powder to lubricate the locking mechanism.
6. If the lock is still not opening, it is recommended to contact a professional locksmith to come and open the lock. They have specialized tools that can quickly open the padlock.
III. Lock Opening and Closing Techniques
1、Lock Picking Technique: Use a metal strip and a thin metal wire. The metal strip should be folded at a 90-degree angle, similar to the cap of a pen, to engage with the lock hole for rotational force. The wire should be moved back and forth near the keyhole to manipulate the lock mechanism.
2、Use a flexible, fine metal wire (a keychain works well) and bend one end into an approximately 135-degree angle. Insert the bent end into the lock hole as far as possible. (This requires practice and can be challenging.)
3. If the key to the lock is lost, a master key can be purchased. A master key can open various types of locks.
