Need to prove when unlocking:

Unlocking companies belong to special industries. Unlocking companies must be filed with the Public Security Bureau and registered with the Industrial and Commercial Bureau before they can open their doors.

1, the security door needs to be unlocked.

You need written proof from any third party (property, neighbors, public security organs, etc.). ) Whether the house to be unlocked is yours or rented by you, the master of the unlocking company will register the identity information of the customer to be unlocked.

Only after the parties sign and confirm can the lock be unlocked (not everyone carries the real estate license with him, even if there is, the locksmith master can't tell the authenticity on the spot).

2. If indoor doors, safes and filing cabinets are unlocked normally, no reference is needed, and the parties need to register to unlock normally.

3. To unlock a car or motorcycle, the party concerned needs to provide a motor vehicle driving license or a written certificate from a third party (property, neighbors, public security organs, etc.). ), and register the identity information of the parties for the record, and the parties can unlock it after signing and confirming.
