Lock Replacement & Upgrade
The house is fifteen years old and every exterior door still wears the light hardware the builder fitted: a short bolt, a thin strike held by two small screws, and a knob lock that never suited a street entrance.
Lock Replacement & Upgrade
In plain words
Lock replacement and upgrade is the service that takes tired or under-built door hardware off and puts hardware suited to the door in its place. It ranges from a like-for-like deadbolt on a back door to a complete refit of every entrance with heavier-grade locks, reinforced strikes and one key for the house. The locksmith first confirms that the person ordering the work has the right to change the lock, then examines the door, measures the existing preparation and recommends hardware that fits it cleanly. The visit ends with each lock tested from both sides, keys in your hand and the packaging and instructions left with you.
How the visit goesThe keys the seller handed over came in a sandwich bag: six unlabelled copies for two locks of different makes from different decades. You have no idea how many more copies exist or who is holding them.

How the visit goes
The key plan for the whole house
A lock is only half of a system; the other half is who holds which key. The locksmith asks how many exterior doors there are, which ones should open with the same key, whether a garage man-door or a shed should join them, and who in the household needs a key of their own. If keys have been lent out over the years, the plan can retire all of them at once. Where copying keys without permission is a worry, a restricted keyway can be offered. Settling this before the hardware is chosen means the new locks arrive ready to be pinned alike rather than fixed up afterwards.
Stepping up the grade of a deadbolt
When the brief is a stronger door, the new deadbolt is chosen for what is inside it: a bolt with a full 25 millimetre throw and a hardened steel insert that spins against a saw, a housing that stands low so a wrench has nothing to grip, and a cylinder with pins that resist picking and bumping. Fitting follows the normal steps, but the locksmith confirms the bolt reaches full extension with the door closed, because a high-grade bolt seated halfway into a shallow pocket behaves like a low-grade one. The strike is upgraded alongside it so both halves of the lock share the same standard.
Every lock tried the way you will use it
Before the tools go back in the van, each lock is operated from both sides with the door open, then closed, then closed hard against the weatherstrip. The latch should catch on its own when the door swings shut, the deadbolt should throw to its stop with a fingertip on the thumb-turn and no shoulder on the door, and the key should turn without lifting or jiggling. You are invited to try each one yourself and to lock up behind the locksmith. Anything that felt marginal has been adjusted, so the door you close that night behaves the same as the one you tested.

What affects the quote
Same fees day, night or weekend
1Strike reinforcement and jamb repair
A reinforced strike with long screws is a modest addition; repairing a jamb split from a forced entry, or fitting a strike box into a frame that has never had one, adds labour and materials.
2Patio and French door hardware
Sliding door mortise locks, foot bolts and flush bolts for an inactive French door leaf are specialty items sized to the door, and they are quoted as their own line beside the entrance work.
3Door material and thickness
Wood, steel and fibreglass doors are drilled and fitted differently, and a door thicker than the standard 45 millimetres needs extension parts, so the door itself shapes part of the quote.
Lock Replacement & Upgrade: questions
Should I rekey my locks or replace them?
Rekey when the hardware is sound and the problem is the key: a lost copy, a move, or too many keys for one house. Replace when the mechanism itself is worn, the housing or bolt is damaged, the grade was never suitable for the entrance, or you want a different function, finish or a keypad. Many visits do both, keeping good locks and rekeying them while replacing the tired ones, all to one key.
How do I look after a new lock so it stays smooth?
Very little is needed. Whatever lubricant and interval the cylinder maker specifies, worked into the keyway with a few turns of the key, keeps the pins free; using the wrong product collects grit instead of helping. Wipe salt off exterior hardware during winter melts. Snug the hinge and strike screws each spring and fall as the door moves with humidity. Cut spare keys from a crisp original rather than a worn copy.
What is a reinforced strike, and is it worth adding?
A standard strike is a thin plate held by two short screws in the jamb, and the jamb is what splits when a door is forced. A reinforced strike or strike box is heavier and is fixed with long screws that pass through the jamb into the framing, spreading the load into the structure. It is one of the most effective upgrades on any exterior door and is usually fitted as part of a deadbolt replacement.
