Technique 1: Using a wire to pick locks
1. Find a relatively hard wire, straighten it, and then bend the end upwards.2. Insert the bent end into the handle of the wrench.3. Insert the wrench into the lock hole, ensuring that the wrench enters the lock hole on the side where the key's tooth engages.4. once the position is aligned, gradually increase the force on the wrench until the pin is lifted.5. Then, turn the wrench to complete the process.
Tip 2: Using a universal key to unlock

Find a universal key and insert it into the lock cylinder. Then, use a hammer to strike the other end of the key while attempting to turn it. In most cases, this will allow you to open the lock.
Technique 3: Using chewing gum to unlock
If you have chewing gum, insert it into the lock to seal it, then push it further inside to "expel" the gum, and finally, use an object to penetrate the lock mechanism to unlock the door.
Technique 4: Using a screwdriver to unlock
If you have a long-handled screwdriver, you can insert it into the keyhole and repeatedly rotate the key while inserting the screwdriver. This will disengage the locking mechanism and allow the lock to open.
Technique 5: Opening Metal Sheets
Prepare a metal strip with 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 metal wire should be moved back and forth near the striker of the lock, and with luck, it can open the lock.
