How can I match the key if I lose it?

Go to a regular door lock and key shop, match keys from downstairs to upstairs, contact the unlocking company to prepare keys, find key blanks, re-prepare, find properties, find unlocking companies, etc.

1. Go to a regular door lock and key shop: usually, you need to use a lock core or a master key to match keys, combined with unlocking technology. Please be sure to choose a reputable door lock and key shop to ensure the safety and reliability of the new key.

2. Matching keys from downstairs to upstairs: This method is relatively simple, but it is necessary to determine the type of door lock to ensure that the prepared keys can work normally. Please operate under the guidance of experienced professionals.

3. Contact the unlocking company to prepare the key: The unlocking company generally has professional unlocking technology and related documents, which can provide safe and reliable key preparation services. Choose a reputable unlocking company to ensure relevant qualifications and insurance.

4, find the key blank, re-prepare: if it is an ordinary lock used at home, remove the lock or call a professional to remove it. Generally speaking, there are two matching methods, one is to try to open N keys, which will be easy to match if there is a good chance, and the other is to disassemble the lock core and match according to the elastic piece of the lock core. This method will not be difficult, but it will take more time.

5. Looking for a property: Generally, a good residential property will have a spare key of the owner's house. You can bring your ID card and other relevant proof materials to the property to find a spare key. If the attribute has a spare key, it will check its identity. If confirmed by contacting the owner of the house, it will open the door with a spare key. If it is confirmed that the key is lost after opening, you need to take the key of the property to make a copy.

6. Find an unlocking company: If the above three methods can't be opened, you need to find a professional unlocking company to handle the door lock. When looking for an unlocking company, you must look for an unlocking company that has a record in the public security bureau and is relatively small or mobile in the street. Property safety cannot be guaranteed, and items may be lost.
