When Should You Repair or Replace a Lock?
Knowing when to repair versus replace a lock can save you money and keep your property secure. A lock that is stiff or requires force to turn may simply need lubrication and adjustment. However, if the internal mechanism is worn or damaged, replacement is the safer option.
After a break-in or attempted break-in, we strongly recommend replacing all affected locks immediately, even if they appear to still work. The integrity of the lock may have been compromised, and a new lock provides peace of mind.
If your locks are old or do not meet current insurance standards, upgrading to a British Standard or anti-snap lock is a wise investment. We can advise on the best options for your property and budget during a free, no-obligation assessment.
