Today i attended a property in chafford hundred grays. The owner had used pj locksmiths a couple of years ago and kept my number. When i arrived they were locked out with a key snapped in the cylinder.  I gained entry to the property and removed the broken key. After testing the cylinder it felt a bit notchy. none of the keys were were very good.  I advised they changed the cylinder whilst i was there. They agreed and  had a much higher security cylinder fitted.
