When Should You Replace a Lock Instead of Repairing It?
Replace when the plug has been scored by a failed entry attempt, the exterior finish has corroded through, the hardware was forced in a break-in, or you are upgrading to keyless. Everything else — stiffness, grinding, a bolt that will not throw — is usually repair, at $50 to $200.
The four genuine replacement triggers
Scoring, corrosion, forced damage, deliberate upgrade. Those are visible and a locksmith should be able to show you the evidence rather than assert it. If you cannot see why, ask. The decision rests on what has actually failed: servicing a cylinder that is simply dirty or dry, against repinning when the concern is who holds a key.
What repair actually covers
Cleaning and relubricating a gummed cylinder, adjusting hinges and strike, repairing a jamb, replacing a worn spring or a single failed component. An hour of labour resolves most complaints about a “broken” lock.
The High Country wrinkle
Exposed elevations here take wind-driven rain and road salt. Hardware on the weather side of a house genuinely does fail sooner than the sheltered side, so it is entirely normal for one door to need replacing while three others do not.
Repair or replace
| Symptom | Usual answer |
|---|---|
| Stiff or grinding cylinder | Repair — clean and lubricate |
| Bolt will not throw fully | Repair — alignment |
| Door must be shouldered | Repair — hinges and strike |
| Plug scored by a failed attempt | Replace |
| Finish pitted and corroded through | Replace |
| Hardware forced in a break-in | Replace, and reinforce the strike |
| Want a keypad | Replace, keeping a keyed override |
The Short Version
- Four genuine reasons to replace — everything else is repair.
- Ask to be shown the damage, not told about it.
- One weather-side door failing is normal here.
