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.
The right deadbolt for a door depends on how the door is used and where it sits. A front door that a family goes through twenty times a day needs a durable mechanism and a finish that shrugs off salt spray and sun; a side door in a laneway wants a heavy bolt and a strike that reaches the framing. Residential deadbolts carry letter grades for security, durability and finish, and heavier commercial-pattern bolts carry numbered grades, so there is a plain way to compare. The locksmith talks through those options, then fits the one you choose with the same care whichever grade it is.

Deadbolt Installation · Cambridge
Scene 1
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.
Scene 2
The finished lock is proved in three stages. With the door open, the thumb-turn and then the key are cycled several times to confirm the bolt throws fully and returns freely. With the door closed, the same tests show whether the bolt clears the strike opening and seats in the pocket; any drag is marked with chalk and the strike is dressed or shifted until the bolt moves with fingertip effort. If the cylinder is being keyed to the household key, it is repinned on the bench and tested from outside with the door closed, and every key that should work is tried before the tools go back in the van.
Scene 3
You should know what is on your door in plain terms, so the visit closes with a short account: the model and grade of deadbolt fitted, its finish, the backset and bore it sits in, whether the cylinder was keyed alike or set to a new key, how many keys were cut, and what was done on the frame side. For a rental, this note is useful for the landlord or building manager, who under tenancy rules is entitled to know what lock is on the unit and to hold a key. For an owner it is one line in the house file that makes the next locksmith visit, whenever it comes, a simpler conversation.
What shapes the quotePreston Locksmith Co.
FeesSame any hour
In most cases, yes. The locksmith examines the jamb for splits and stripped screw holes, glues and pins any cracked section, and fits a full-length jamb reinforcer under the strike so the new long screws bite into sound wood and the stud behind. A new pocket is bored to the correct depth. Where the jamb is beyond repair, replacing that section of frame is discussed before any lock goes on.
Know which doors you want bolted, what they are made of, and whether each already has a deadbolt or only a knob. A photo of the door face and edge helps. Have any existing keys to hand, decide whether you want everything on one key, and mention glass near the lock, a storm door in the same opening, or a rental agreement. If you have already bought hardware, keep the box and template together.
The knob or lever holds the door shut with a spring latch: a bevelled tongue that snaps into the frame and can be pushed back by anything slid into the gap. A deadbolt is a solid rectangular bar driven by the key or thumb-turn alone, and when fully thrown it locks in place so it cannot be pressed back from the edge. The knob keeps the door closed; the deadbolt keeps it locked.
