Why Choose a Deadbolt?
A deadbolt can add a dedicated locking function to a compatible door while allowing the visible trim to coordinate with the rest of the entry hardware. The correct choice depends on the door application, cylinder arrangement, security requirements, existing preparation, keying needs, and applicable building or egress requirements.
- Dedicated locking function: A deadbolt uses a separate bolt and locking mechanism rather than relying only on the spring latch in a knob, lever, or handleset.
- Multiple cylinder configurations: Shoppers can compare keyed exterior cylinders, interior thumbturns, double-keyed configurations, and one-sided locking arrangements.
- Broad style selection: The collection includes round, square, rectangular, arched, low-profile, traditional, transitional, contemporary, and modern trim designs.
- Finish coordination: Available deadbolts can be coordinated with compatible handlesets, door knobs, levers, hinges, pulls, and other visible door hardware.
- Replacement and project options: Products are available for individual replacement projects as well as larger residential, multifamily, and other supported hardware packages.
- Authorized dealer support: Coastal Hardware Store can help shoppers compare functions, finishes, door preparation, cylinders, keying requests, and coordinating products before an order is placed.
Types of Deadbolts & Door Locks Available
Single-Cylinder Deadbolts
Single-cylinder deadbolts generally use a keyed cylinder on the exterior side of the door and a thumbturn on the interior. They are commonly selected for front entries, side doors, garage-entry doors, and other compatible openings where exterior keyed access and interior thumbturn operation are appropriate. Trim designs range from understated round and square styles to larger decorative profiles intended to coordinate with entry hardware.
Double-Cylinder Deadbolts
Double-cylinder deadbolts use a keyed cylinder on both sides of the door instead of an interior thumbturn. A key is therefore required to lock or unlock the deadbolt from either side. Because this configuration can affect emergency operation and egress, confirm that it is appropriate and permitted for the specific opening before ordering or installation.
Single-Sided Deadbolts
Single-sided deadbolts operate from one side of the door and may have no keyed cylinder or visible trim on the opposite side, depending on the model. They are often considered for compatible patio, side, or specialty doors where exterior key access is not required. Review the exact exterior appearance, interior operation, door preparation, and included components for the selected product.
Entry Lock & Deadbolt Combination Sets
Some products in this collection combine a keyed entry knob or lever with a coordinating deadbolt. These sets can simplify the selection of matching trim for an entry door, but the included components, cylinder arrangement, keying, center-to-center spacing, and required door preparation vary. Confirm whether the product includes both locking components and whether it fits the existing door before ordering.
Privacy Bolts & Surface Bolts
The collection also includes privacy bolts and surface bolts. Privacy bolts are intended for supported interior privacy applications rather than serving as conventional exterior keyed deadbolts. Surface bolts mount visibly to the face of a door or panel and may be used for compatible paired doors, inactive door leaves, Dutch doors, or other specialty arrangements. These products use different preparations and serve different purposes than standard tubular deadbolts.
How to Choose the Right Deadbolt
Begin with the door application and required locking function, then narrow the selection by cylinder arrangement, door preparation, documented security requirements, keying, style, and finish. Products from different manufacturers should not be assumed to use the same dimensions, cylinder, strike, or installation method.
- Identify the application: Determine whether the lock will be used on a front entry, side entrance, garage-entry door, hinged patio door, rental property, multifamily opening, or another supported application.
- Choose the correct cylinder arrangement: Decide whether the opening requires an exterior key with an interior thumbturn, keyed operation on both sides, or operation from only one side.
- Verify security requirements: If the project requires a particular security grade, listing, testing standard, cylinder feature, or other documented designation, confirm that requirement in the manufacturer's information for the exact product. The collection title is not a shared certification for every item.
- Measure the existing door preparation: Check the cross bore, edge bore, backset, door thickness, bolt and strike preparation, trim dimensions, and any spacing between the deadbolt and a separate knob, lever, or handleset.
- Review cylinder and keying options: Keyway, cylinder type, keyed-alike availability, rekeying features, and compatibility with an existing key system vary by manufacturer and product. Confirm all keying requirements before ordering.
- Coordinate the complete entry: Compare the exact manufacturer finish, trim shape, and product family with the handleset, knob, lever, hinges, door pull, and other visible hardware.
Materials, Styles & Finishes
The deadbolt collection spans simple low-profile designs, clean geometric trim, decorative traditional profiles, and specialized hardware for one-sided, privacy, and surface-mounted applications. Product construction and base materials vary by manufacturer and series. When material composition is important, review the individual product page rather than inferring the underlying material from the finish name or product photograph.
Current collection filters include products shown in finishes such as Flat Black, Matte Black, Satin Black, Satin Brass, Lifetime Satin Brass, Satin Nickel, Polished Nickel, Polished Chrome, Oil Rubbed Bronze, Venetian Bronze, Unlacquered Brass, Polished Brass, Satin Chrome, Brushed Stainless Steel, Satin Stainless Steel, and manufacturer-specific bronze or steel patinas. Availability varies by model and function.
Similar finish names from different manufacturers may not be identical in color, sheen, texture, or aging characteristics. Coordinate products using the manufacturer's complete finish name and code whenever possible. Unlacquered, living, patinated, or otherwise evolving finishes may change with handling, age, and environmental exposure, so review the applicable care instructions and finish-warranty terms before ordering.
Featured Deadbolt Brands
The current collection includes residential, decorative, architectural, and specialty deadbolt products from multiple manufacturers. Coastal Hardware Store is an authorized dealer for every brand represented on the website. Available functions, finishes, cylinders, warranties, and lead times differ by manufacturer and product family.

Installation & Compatibility
Deadbolt installation requirements vary by manufacturer, function, and model. Before ordering, compare the product specifications with the existing door preparation, including the required bore dimensions, backset, door thickness, bolt and latch preparation, strike, cylinder arrangement, trim diameter, mounting hardware, and any center-to-center spacing that applies to the complete entry set.
For replacement projects, do not assume that a new deadbolt will use the existing holes, cover the same footprint, accept the same cylinder, or align with the current strike. Decorative trim can also differ in size even when two products use a similar tubular preparation. If the deadbolt will be installed above a handleset, knob, or lever, verify the required spacing and make sure the products can be installed together without trim interference.
Proper alignment and installation are important parts of the complete door system. Follow the manufacturer's instructions for the selected lock, bolt, strike, fasteners, and door preparation. New preparation, mortising, specialty doors, regulated openings, or projects with documented security requirements may call for a qualified door-hardware installer or locksmith.

Frequently Asked Questions About Deadbolts & Door Locks
What is the difference between a single-cylinder and double-cylinder deadbolt?
A single-cylinder deadbolt generally has a keyed cylinder on the exterior and a thumbturn on the interior. A double-cylinder deadbolt has keyed cylinders on both sides, requiring a key for interior and exterior operation. Before choosing a double-cylinder model, verify that it is appropriate and permitted for the specific opening.
What is a single-sided deadbolt?
A single-sided deadbolt operates from one side of the door and may have no keyed cylinder or visible trim on the opposite side, depending on the model. These locks can be used for compatible patio, side, or specialty doors where exterior key access is not required. Confirm the product's exterior appearance and door-preparation requirements before ordering.
What should I look for in a high-security deadbolt?
The term “high-security” should be supported by product-specific manufacturer documentation rather than the collection title alone. If your project requires a particular security grade, listing, test standard, cylinder feature, or other performance designation, verify that information for the exact model and make sure the complete door, frame, strike, and installation meet the project's requirements.
Can deadbolts be keyed alike?
Keyed-alike service may be available for compatible products, but options differ by manufacturer, cylinder, keyway, and product family. Contact Coastal Hardware Store before ordering when several locks must use the same key, be keyed differently, or match an existing key. Keying requests may add processing time.
Can I replace a deadbolt without replacing the handleset?
Often, but compatibility must be confirmed. Compare the existing bore, backset, door thickness, strike, trim footprint, cylinder, finish, and spacing between the deadbolt and handleset. A replacement deadbolt may fit the mechanical preparation but still differ in visible size, shape, or finish.
Do all deadbolts fit the same door preparation?
No. Bore dimensions, backset, door thickness, bolt preparation, strike requirements, cylinder type, trim size, and mounting details can vary by manufacturer and model. Single-cylinder, double-cylinder, single-sided, privacy, surface-mounted, and combination products should not be assumed to use the same preparation.
