Lock sticking, jamming or just not as easy to use?

Believe me, its a sign that you need to do something.

It could be as simple as a service (you are servicing you lock with a graphite lubricant every 6 months and the mechanism is oiled annually)?

It may be a keep needs adjusting, a hinge needs a tweak or a gearbox strip down. These jobs are relatively simple to do but could save your door from breaking.  You know it wont lock/unlock at the most inopportune time. and you will be faced with an emergency call out cost.

Let Dawson Sawyer Locksmiths repair these problems rather than replace.
