Most UPVC or Composite Doors are locked via a Euro Cylinder Barrel. Once you have lifted your Door Handle and the Multi-Point Locking Mechanism has engaged, you then turn your Key and Deadlock the door. Quite often these locks can become stiff or completely jammed, this is usually due to the Pins & Springs inside these locks becoming jammed or out of place, which means the lock needs to be replaced. We have access to hundreds of different Sizes, Makes and Standards of these Euro Locks which we can supply and fit at an excellent price. Call for further details: 0191 4862456 or 07701055108.
