Ottawa winters are hard on locks and frames. If a cylinder in Beacon Hill, Bells Corners, or downtown suddenly turns hard after a cold snap, we diagnose whether it is dirt, ice-related binding, strike misalignment, or a failing mechanism — then repair what we can before recommending replacement.
This is the primary lock repair page for Can-Lock Security — residential and commercial door lock repair, cylinder and mechanism work, and honest repair-versus-replacement advice. City pages may mention lock repair locally; the general intent stays here.
Common lock repair situations
- Sticking locks / key not turning smoothly — debris, dried lubricant, or worn pins inside the cylinder
- Loose locks — hardware that has walked in the door slab or a strike that has loosened in the frame
- Deadbolt repair — bolt that hesitates, will not fully throw, or scrapes the strike
- Lock cylinder repair — when the plug or pin stack is the failure point rather than the whole lockset
- Lock mechanism repair — springs, cams, and internal linkage on residential and commercial hardware
- Commercial lock repair — higher-cycle storefront and office hardware that wears faster than home locks
- Residential lock repair — house and condo entry hardware, including seasonal binding after cold snaps
- Key broken in lock — extraction first, then cylinder assessment: broken key extraction
Repair vs replacement
If the lock is mechanically sound, we repair and adjust. If the cylinder or body is failed, cracked, or worn past reliable service, we explain replacement — including when a rekey still solves access control without new hardware. For locks that have already seized or jammed shut, see broken lock repair; that page covers failed hardware, while this page owns general lock repair and troubleshooting intent.
The Real Question Behind Most of These Calls
Most people calling about a lock problem aren't asking "how do I fix this" — they're asking "is this actually a problem, or am I overthinking it." Both are reasonable questions, and getting an honest answer to the second one is often just as useful as the repair itself.
Why Can-Lock Security
Mobile and family-run, and genuinely willing to tell you when a lock doesn't need anything done to it. Pricing is explained clearly, and we don't push repair or replacement your specific lock doesn't actually require.
