Deadbolt Installation: questions about the price

Very little is needed. Each spring and autumn, lock the door from inside and feel whether the bolt still goes home without the door being pulled; if it hesitates, the door has moved with the season and a small strike adjustment restores it. Whatever lubricant the lock's own maker specifies keeps it smooth, often a dry PTFE or graphite type in the keyway and along the bolt, though some cylinders are meant to be serviced with oil. In winter, wipe road salt off the outside trim to protect the finish.

Storm door or restricted clearance

A tight storm door, a narrow lock stile or a decorative panel at bolt height can require low-profile trim or a shifted position, which is settled and quoted at the assessment.

Glass near the lock

A captive thumb-turn, laminated glass, security film or a relocated bolt height each carry their own cost, and the choice you make about glass shapes that part of the quote.

Keying alike or a fresh key

Pinning the new cylinder to your existing key, or setting several doors to a new key, is bench work quoted per cylinder, plus the number of keys you ask to have cut.
