The security door is locked. How to unlock without a key?

Go to the property right away and explain your situation. The property will help you find a way, such as looking for an unlocking company.

In addition, if it is a rental house, whether it is locked inside or outside, call your landlord and the landlord will send you the key as soon as possible. No matter which landlord, it is impossible to leave one or more spare keys.

If you have a phone card or hard card, try to insert the hard card into the door. With luck, the hard card may pull the tongue out of the lock, but the possibility is 20% to 30%. Don't get your hopes up.

Note: If there is no gap in the door, and it is a relatively strong security door, and no one at home has a key and the door is locked, then you have to ask the locksmith for help, but after using this method, you need to replace the new door lock.

If we are particularly anxious to enter the house, we can kick the door hard or hit the door with our bodies. If you are afraid of being hit, you can also borrow tools from your neighbors and split the door open. This requires a new door lock or even a new door.
