You can find someone who sells security doors or repairs locks.

Anonymous users2024-01-22Just change the lock cylinder directly...
The door does not necessarily have its own lock cylinder brand Generally it is outsourced, such as the famous Panpan anti-theft door The high-end series uses CEI's colorful lock cylinder, which not only makes anti-theft doors and wooden doors, but also has its own brand of lock cylinder, which I know is Changen invincible CEI, which is a relatively high-end product. Adopt it, haha.
If you don't have a key, you can't match it, and if you can't do it, you can change the lock.
An security door has an area of about 2 (square meters) and a width of about 1 (meter).
It's because the deadbolt of your door is stuck too tightly, and the key force is too small to open, and you can use the handle inside to exert more force, so it opens. All you need to do is tap the deadbolt a little in the direction of the door opening.
