Today i was called to a property in Grays where the owner had put the key in front door and the key jammed. He asked me come out to see if i could remove the key as the dead bolt was still out and the door would not open . I removed the key then removed the cylinder to find it was jamming up sometimes i checked the lock system on the door which was fine i advised the customer and i fitted a new cylinder this the 3rd time this brand of cylinder has failed and they are not cheap
