When a door needs a deadbolt
Some doors need a new deadbolt. Others have hardware that no longer engages the frame properly or needs a different security grade.
A door without a deadbolt
A new deadbolt can be fitted by preparing the door and frame for the lock hardware.
A worn locking mechanism
If the existing deadbolt is worn or damaged, replacing the assembly may be more appropriate than repairing it.
A bolt that does not seat
A deadbolt must enter the strike opening freely and reach its full throw. Door and frame alignment matter as much as the lock.
An older basic-grade lock
A Grade 3 deadbolt can be replaced with a higher-grade model when the door and hardware allow it.
Different keys on one door
A new deadbolt may be keyed to the existing door key when the two locks use compatible keyways.
A change of lock hardware
Replace your existing deadbolt with a different style or finish to match the rest of your door hardware.
The details behind a working deadbolt
A deadbolt is only as useful as its fit in the door and frame. Installation includes checking the hardware, the bolt travel and the strike.
Door preparation
We inspect existing openings or prepare a new bore when the door has never had a deadbolt.
Deadbolt fitting
The lock is fitted so its bolt can extend the full 1 inch into the frame without binding.
Reinforced strike
A reinforced strike plate is secured with 3 inch screws intended to reach the wall stud behind the frame.
Final operation check
We operate the lock with its key and check that the door latches, the bolt travels fully and the hardware works without forcing it.
What affects the installation cost
Deadbolt installation starts from $85 per door plus the lock. The technician examines the door and gives you a written price before work begins.
Installation labor
The starting labor price is separate from the cost of the selected deadbolt and any additional hardware needed.
Service call fee
A separate $39 fee covers travel and inspection inside the service area. It applies to the visit and is not credited toward installation.
New bore or replacement
A door with no existing deadbolt needs an opening prepared. Replacing an existing lock involves checking whether its openings can be reused.
Lock grade and hardware
Grade 1, Grade 2 and Grade 3 deadbolts offer different levels of hardware strength. Your selection affects the parts price.
Door and frame condition
The condition of the door and frame affects the price. Any needed adjustment is listed in the written price you approve before work begins.
From door inspection to final test
We check the door before cutting or fitting anything, explain the hardware options and confirm the lock works with the door closed.
Describe the door
The office asks for your address, door and lock type, and what is wrong with the existing deadbolt or whether the door has never had one.
Verify and examine
The technician arrives with photo ID and a work card, verifies your authority to approve the work and checks the door and frame.
Review the written price
We confirm the chosen hardware, preparation and adjustments. You approve the written price before any drilling or installation.
Fit and test the lock
We install the deadbolt, check its full throw and operate it with you. The final itemized invoice separates the visit, labor and parts.
Questions about fitting a deadbolt
The right deadbolt depends on the door, the existing hardware and how the bolt meets the frame. Here are the details homeowners often ask about.
Call (702) 000-0000All questionsCan you install a deadbolt on a door that has never had one?
Yes. A new installation involves boring the door for the lock and preparing the frame for its strike. The technician checks the door before quoting and doing that work.
What is the difference between Grade 1, Grade 2 and Grade 3?
ANSI/BHMA Grade 1 is the highest grade and is used for commercial and heavy residential applications. Grade 2 suits residential and light commercial use, while Grade 3 is the basic residential grade.
Can the new deadbolt work with my existing house key?
Often, when the new deadbolt and existing lock have compatible keyways. We check compatibility before offering to key them alike. Different lock designs cannot always share a key.
Can I buy my own deadbolt and have you fit it?
Yes. Customer-supplied deadbolts receive a 12-month workmanship warranty on installation labor only. Hardware carries its manufacturer’s warranty. Cairn handles hardware warranty claims only for locks it supplied.
Why does the strike plate matter?
The deadbolt should extend a full 1 inch into the frame. A reinforced strike plate secured with 3 inch screws that reach the wall stud anchors the lock into the wall framing, not just the door trim.
