Not every failing lock needs replacing. A stiff multipoint often comes down to a dropped door or a dry gearbox, and a key that turns halfway is usually a worn cylinder rather than a dead one. Castle Locksmiths Limited diagnoses the fault before quoting a part, carries the common gearboxes and cylinders on the van, and repairs where a repair genuinely holds.

Multipoint strips with one failed gearbox, mortice cases with a bent follower and cylinders with worn pins are all worth saving. Anything drilled, forced or corroded through the casing gets replaced.
For deciding between saving or replacing a lock, it's essential to know what can be repaired and what's beyond salvage. We often find that worn cylinders, drifting gearboxes, and sticking handles can be repaired effectively. These issues usually don't require a full replacement, saving both time and money.
Our goal is to restore full function with precise repairs, especially when dealing with common problems like these.
However, Bradford's unique climate presents challenges, particularly for timber doors on stone terraces. Each winter, the weather off the Pennines causes these doors to swell, often jamming mortice locks.
In such cases, a careful adjustment can restore functionality without needing a new lock. Understanding the specific needs of locks in our area helps us provide the best solutions.
We're ensuring that your locks work smoothly, keeping your home secure and your day uninterrupted.

Properly diagnosing a lock fault is essential for effective repair. We take a methodical approach to ensure we get the job done right the first time.
First, we test key resistance to see if it's sticking or turning smoothly. This can indicate an issue with alignment or internal components.
Next, we check the door's alignment against the keep. Misalignment can often be mistaken for a lock issue when it's actually the door's position.
We listen carefully for any signs of spring failure, which might suggest internal wear. A common misdiagnosis is blaming a uPVC multipoint gearbox fault on the cylinder, especially with retrofitted doors on the outer estates.
By ruling out whether the problem is due to door drop or internal wear, we avoid unnecessary replacements. This detailed diagnosis saves time and means your lock is repaired efficiently.

Identifying and resolving issues with multipoint locking systems is our next focus. When hooks, rollers, or gearboxes seize up, it can compromise the security of your door.
First, we identify the gearbox model, which is vital for matching it to the existing hardware. Brands like Yale require precise replacements to function correctly.
Next, freeing jammed hooks and rollers is necessary. We meticulously realign the keeps to deliver smooth operation. This involves adjusting them to the correct position and testing for proper engagement.
Proper lubrication is key—using the right lubricant delivers longevity and prevents future sticking.
Finally, once everything is aligned and moving smoothly, your door's locking system regains its full functionality. We take pride in bringing your multipoint strip back to life on our first visit, restoring smooth, secure operation for your home.
Let's handle the complexity, so you don't have to worry.
Encountering cylinder faults, stuck keys, and worn pins can be frustrating, but we're here to help. We've all been there—turning the key only to feel it stick or, worse, snap inside the lock.
Our skilled team is ready to handle these issues efficiently. We specialise in cylinder surgery, expertly extracting broken keys and addressing worn pins that cause spinning cams.
After extraction, we offer rekeying services to make sure your existing keys keep working. However, sometimes an upgrade is the smarter choice. For enhanced security, we recommend upgrading to a TS007 3-star anti-snap unit, like the Avocet ABS. This option provides superior protection, especially if your current lock is showing signs of wear.
Our goal is to have your lock repaired or upgraded on the first visit.

Moving from cylinder issues to mortice and rim lock repairs, our focus shifts to the beautiful Victorian joinery found in Heaton and around Lister Park.

Re-cutting worn keeps is essential so that a BS3621 five-lever lock latches cleanly.
Our expertise allows us to tackle these challenges efficiently, maintaining the original door furniture where owners wish to preserve the unique charm of their homes.

Our team documents every repair meticulously, providing you with evidence of compliance. This documentation is vital for validating your insurance claims.

You can rely on us to keep your home secure and your insurance valid.
Good quality mortice and rim locks on solid joinery usually repay a repair, and so do multipoint strips where only the gearbox has failed. Worn budget cylinders and locks below current standards are better replaced.
By testing the door open and closed before touching anything. A key that fights only when the door is shut points at alignment, not the lock; a handle that lifts but will not throw the hooks points at the gearbox. Diagnosing first avoids paying for the wrong part.
Often, yes. Jammed hooks and rollers, worn gearboxes and misaligned keeps are all repairable items, and common gearboxes travel in the van. A strip that is bent or seized along its length is a replacement.
Yes. Older joinery in Bradford's terraces is worth keeping, so cases are freed, springs and levers replaced and keeps reset rather than cutting the door about for a modern lock it was never built for.
Where a lock is repaired it is returned to correct working order, and where a part is replaced we fit hardware to the recognised standard and name it on the invoice, so the paperwork matches your policy.
