When to Repair vs. Replace a Lock

Not every lock problem requires a full replacement. Often, a skilled locksmith can repair the existing lock for a fraction of the cost of replacement. However, in some situations – such as when a lock is heavily worn, very old, low quality, or has been compromised in a burglary – replacement is the better choice.

Our locksmiths will always inspect your existing lock, explain your options clearly, and recommend the most cost-effective solution for your specific situation. We never upsell unnecessary work.

Upgrading Your Locks for Better Security

If your home still has builder-grade locks installed when it was built, it may be significantly under-secured. Many standard door locks can be picked or bumped in seconds by experienced burglars. We recommend upgrading to high-security cylinder or deadbolt locks, and considering the addition of digital or smart lock technology for maximum convenience and protection. See our Digital Lock Installation service for more information.

Signs your lock needs attention include difficulty turning the key, the lock feeling stiff or grinding, visible physical damage, a key that doesn't retract the latch fully, or a lock that was involved in a break-in. Our locksmiths will assess your lock and advise on the best course of action.
