Deadbolt Installation in Bridgenorth
The bolt on the front door is keyed on both sides. Getting out at night means finding the key in the dark, and with a toddler in the house you have decided the inside should turn by hand.
Deadbolt Installation
In plain words
Deadbolt installation puts a solid bolt lock on a door that either has none or has one that is past its useful life. Unlike the spring latch in a knob or lever, a deadbolt is a straight bar of metal that only moves when the key or thumb-turn moves it, so a card slipped into the gap or a shove against the door does nothing. The locksmith bores the door if needed, fits the bolt and cylinder, cuts a proper pocket in the frame and secures a reinforced strike with screws long enough to reach the framing. You are left with a door that locks with a firm, full throw.
How the visit goesThe old deadbolt has grown lazy. You turn the thumb-turn and the bolt creeps out halfway, then needs a second push with the door pulled tight. Some mornings the key has to be jiggled before it will come back out.

How the visit goes
Glass, sidelights and what is within reach
Glass changes the conversation about which deadbolt to fit. A pane in the door or a sidelight within an arm's reach of the lock means an inside thumb-turn could be reached by breaking the glass, which is why double-cylinder deadbolts are sometimes suggested. The locksmith measures the distance from the glass to the lock, notes whether it is tempered, laminated or plain, and lays out the options: a captive thumb-turn that needs a key only when you choose, a laminated pane or a tested security film that can delay an arm, or moving the bolt height. The aim is a door that keeps a stranger out and still lets everyone inside leave with one turn of the hand.
Fitting the bolt and setting the backset
The bolt assembly slides into the edge bore with the faceplate set the way its maker marks, commonly the word "top" facing up. Most residential bolts adjust between 60 mm and 70 mm by twisting or sliding the faceplate, and the locksmith sets it to the backset measured earlier so the tailpiece from the cylinder lands in the centre of the bolt's cam. The bolt is secured with its two short screws, and the locksmith works it in and out by hand to feel that it runs freely through the door without rubbing on the bore. On an insulated door a round drive-in collar may replace the flat plate where the edge is too thin to mortise.
A safer way out as well as a stronger way in
With a thumb-turn inside, everyone in the household can leave through this door without hunting for a key, day or night. The locksmith walks the family through the thumb-turn and shows children how it turns. If a double-cylinder bolt was replaced, the inside key is no longer needed at all and can be retired. Where glass sits near the lock, whatever measure you agreed on, a thumb-turn that locks with its own small key, a laminated pane, or a tested security-film system that can delay an arm's reach, is in place, so security did not come at the cost of a clear way out.

What affects the quote
Same fees day, night or weekend
1Removing and disposing of the old hardware
Some visits end with the old deadbolt and strike left with the homeowner, and others ask for it to be removed and hauled away. Taking the old hardware away adds a small amount of time and is agreed before the new deadbolt goes in.
2Travel to the property
Distance and access are part of any call-out: a house on a suburban street and a rural property down a long road involve different driving time, and the quote says so.
3Strike and frame reinforcement
A reinforced strike with long screws is standard; a full-length jamb reinforcer, a strike box or repairs to a split jamb after a forced entry are extra items quoted on their own.
Deadbolt Installation: questions
Can a deadbolt be added to a door that only has a knob?
Yes, on nearly any wood, steel-clad or fibreglass entry door. The locksmith marks a spot above the knob, clamps a jig to the door and bores a cross hole through the face and a smaller hole through the edge, then cuts a pocket and fits a strike on the frame. The main things checked first are the door's thickness, what is inside it at that height and whether glass sits close by.
What do lock grades mean when I am picking a deadbolt?
Residential deadbolts are graded under an industry standard in three categories, security, durability and finish, with letter grades from C through A, so a lock marked with three A grades has met the highest level in each. Heavier commercial-pattern bolts are graded 1, 2 or 3, with 1 the highest. The grades let you match hardware to a busy family door or an exposed side entrance without relying on the weight of the box.
Can a keypad or smart deadbolt be fitted instead of a keyed one?
Yes, and the preparation is the same. Many electronic deadbolts use the standard 54 mm bore and the same edge bore, so a door cut for a mechanical bolt often accepts one, and a keyed bolt fitted today can usually be swapped for a keypad later, subject to that model's own bore, backset and thickness needs. The locksmith checks door thickness against the model, fits a reinforced strike as usual, sets up codes with you and shows where the backup cylinder or battery terminals are.
