Today, Our Ocean Lock Factory holds a customer’s meetting in the TianRui housing estate.And we bring a common wood door which is locked.Then we call our factory master Zhou who has rich experience in the lock cylinder for about 15 years to open the wood door.

Next, the amazing thing happened.Master Zhou only takes 5 seconds to open the locked wood door. So impossible and it make the customers very surprise.

Master Zhou said now the thief uses very advanced equipment to open the cylinder lock. So the common lock cylinder is useless agaist this equipment.But now the Grand A lock cylinder is coming, and its seurity is very good. In the future, the Grand A quality will take place of the common lock cylinder in the market.
