Locksmiths make more money replacing locks than repairing them — which is exactly why you should know the signs that repair is the right call. Here are seven symptoms we fix regularly without replacing the hardware.
1. The key is hard to turn
Usually dirt, dried lubricant, or worn pins — a professional cleaning and repinning often restores smooth operation. (Skip the WD-40; it gums up over time. Dry graphite or a lock-specific lubricant is what pros use.)
2. You have to jiggle or lift the key
Classic pin wear. Repinning the cylinder to fresh pins — or decoding and cutting a fresh key to factory depths — solves it completely.
3. The deadbolt won't extend fully
A bolt that doesn't fully throw isn't really locking. Nine times out of ten this is strike-plate misalignment from a shifted door — a straightforward adjustment, not a lock problem at all.
4. The knob or lever is loose and floppy
Worn springs or a loose spindle. Inexpensive parts, quick fix, and the handle feels new again.
5. The key broke off inside
Extraction is routine, and the cylinder is usually unharmed. We pull the fragment, cut you a fresh key, and you're done.
6. The lock freezes in winter
Moisture in the cylinder. We free it, dry it, and treat it — and show you how to prevent recurrence.
7. It's just old and cranky
Quality locks are serviceable machines. A full disassembly, cleaning, and rebuild can give a fine old lock decades more life — often the right call for vintage hardware in pre-war buildings.
When is replacement actually right? Cracked housings, obsolete parts, cylinders worn smooth, or security so outdated the lock is decorative. A trustworthy locksmith shows you the failed part and explains the math. If someone pushes replacement without showing you why, get a second opinion — preferably from us at (212) 671-0532.
