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.
