1. Breakthrough aviatic sophisticated mechanical procedure control technology, breakthrough traditional conception on lock use;
2. Obtain 5 national patents, 2 inventions;

3. Complicated and multi-times cryptography combination, adopt any 6characters to order, the order times can be high up to 665 thousands.

4. No need key, no need power supply

5. Triples anti-decode function;

6. Triplex anti-peeping operation;
7. Easy and free to change code.

Change Password:
If you need to change the password, loosen the cover slab off the back.
Hold the pulling eye of the lock core and take the core out.
Altogether there are 12 cryptographic keys among which 6 are marked with numbers from 1 to 6. If you insert the first cryptographic key in the No.5 keyhole, it represents that the first number of the password is 5;
If you insert the second cryptographic key in the keyhole marked with #, it represents that the second number of the password is #;
If you insert the third cryptographic key in the No. 7 keyhole, it represents that the third number of the password is 7;
For example, the new password would be 5#7… and the last three numbers you decide.
After the setting, put the lock core back and close the faceplate.
Then your new password will be established.

Anti-peeping Operation
Someone may watch you when you enter the password. Don’t be worried. If your password is 0#123, then you can enter 480931#…0#123, or 908#1237…*0#123#3. It will not destroy the password to press the right numbers in order.
If you find someone watching you when you have entered the password, you can do like this: press *0#12389789… and the lock will not open, because the password has been destroyed by the eight numbers. Operate according to the two methods mentioned before and then you can unlock the door.
Please remember your password does not change, it is just a way to protect your true password.
