Mortice, Latch and Cylinder Repair Service Explained
24hrs Locksmiths repairs the locks on timber doors and the cylinders used on most front and back doors, for homeowners, landlords and businesses across Newcastle upon Tyne. The aim is to fix the part that caused the fault and leave you with a door that locks without a fight.
Stiff Keys, Loose Cylinders and Latches That Will Not Hold
Typical jobs include a mortice lock that won't throw its bolt, a night latch that sticks or lets the door drift open, and a cylinder that moves in the door or catches on the key. We also deal with loose handles and keys that turn without moving anything. A door that can't be locked at all is treated as urgent.
How the Repair Is Done on Site
- We try the key, handle and latch with the door open, then closed.
- The fault is traced to the lock itself or to the way the door sits in its frame.
- You're told what needs doing, which parts are involved and what it costs.
- The part is repaired, adjusted or swapped, and the lock is tested in normal use.
A Lock That Works Without Force When the Job Is Done
The quote is free and agreed before work begins. You'll get a plain explanation of what went wrong, and the lock is tested before the visit ends. Parts that still work are left in place. If more damage turns up once the lock is open, the extra work and its price are explained before anything else is done.
Which Door Locks Can Be Repaired?
This service covers locks on timber doors and the cylinders used on many door types. Multipoint mechanisms on uPVC and composite doors have their own uPVC door lock repair service, which deals with gearboxes, lever handles and dropped doors.

Mortice Locks on Timber Doors
A mortice lock sits inside the door edge and throws a bolt into the frame. Worn levers, a damaged bolt or a strike plate that has shifted can make the key stiff or stop the bolt going fully home. The timber around the lock gets checked as well, because a good lock in a split frame still won't hold.
Night Latches and Rim Locks
Night latches lock the door as it closes. They're common on the front doors of Victorian terraces and Tyneside flats in Heaton, Fenham and Sandyford. When a latch catches, won't retract or lets the door drift open, the keep and the fit of the door are checked along with the latch.
Lock Cylinders
A cylinder that moves in its housing, catches on the key or turns without working the lock is checked to find out why. If it has to come out, a compatible anti-snap cylinder can go in its place.
Keep twisting a stiff key and it may bend or snap, which turns one job into two. If that's already happened, our broken key extraction service takes out the broken piece and checks the lock for the wear that caused it.
Stiff and Jammed Door Locks
A lock that resists the key usually shows one of three patterns. Each one leads to a different repair.
Is the Lock or the Door Causing the Stiffness?
When the key turns freely with the door open but drags once it's shut, the frame or keeps are usually pressing on the bolt. Stiffness in both positions points to the cylinder or another part inside the lock.
The Key Turns but the Door Stays Shut
This usually means a fault between the cylinder and the mechanism it drives. The door may need opening before the lock can be inspected, and non-destructive door opening is tried before any method that would damage hardware you could keep.
A Lock That No Longer Secures the Door
When the bolt or latch won't engage, the mechanism, keeps and alignment are checked together. It isn't always the cylinder. Call to check availability for an urgent callout if the fault leaves your property unsecured, or browse all our locksmith services if the door needs other work too.
When Is Repairing an Existing Lock the Right Choice?
Repair makes sense when the lock is still sound and the fault can be put right by adjusting it, tightening loose parts or fitting a compatible replacement part.

Replacement is the better choice when the lock case or bolt is badly worn, damaged beyond a sensible repair or no longer made, or when the same lock keeps failing. Then our lock replacement service fits a new lock that suits the door and the way it's used.
Will You Need New Keys?
Many repairs keep the existing cylinder, so your keys still work. If the cylinder or the whole lock is replaced, new keys come with it. You'll be told before you agree to the work, which matters in a house where several people hold keys.
Period Homes, Tyneside Flats and Newcastle City-Centre Premises
Owners of larger period homes in Gosforth and Jesmond may want the original mortice locks kept working rather than replaced. Tyneside flats have separate upstairs and downstairs front doors, and each one can be repaired without touching the other.
Landlords with student lets near Newcastle University and Northumbria University can book repairs around tenancy changeovers, so the locks work before new tenants move in. Shops, offices and managed buildings in the city centre can have entrance doors and communal locks repaired too. If a lock is getting worse but still works, request a quote for a planned repair now, while there are more options than there will be once it fails.
Cost Factors for Mortice, Latch and Cylinder Repairs
The quote depends on the fault, the type of lock, how easy the parts are to reach, whether anything needs replacing and when you need someone there. Adjusting a sticking latch is a small job. Opening a door with a failed mechanism and rebuilding the lock is a much bigger one. Some faults can only be priced fully once the lock is open, and our locksmith prices page explains what affects a quote.
