How to identify the type of locks 2) Class B anti-theft door lock core: The B-class lock key is a flat-panel key with a double-row marble slot. The difference with the A-class lock is that there is a row of curved and irregular lines on the key surface. The main types of lock cylinders are 3 types, computer double-row lock core, double-row crescent lock core, double-sided vane lock core.
