At Affordable Locksmiths 24-7 we are noticing an increasing amount of multipoint locks in the Bexleyheath area breaking down due to lack of lubrication. If you have a multipoint locking system on the entrance to your property please take the time to oil the lock as they can be problematic if not sufficiently lubricated from time to time. use a good quality 3 in 1 oil, this will prolong the life of the lock a good deal.
