Secure your home with our collection of high-quality Deadbolts — durable locking hardware designed for exterior doors,
entry doors, garage doors, or any door that needs maximum security and peace of mind. Whether you want a simple single-cylinder deadbolt
or a more heavy-duty security lock, you’ll find reliable options built to strict residential standards at DoorCorner.com.
A deadbolt is one of the most effective and trusted forms of door security — it uses a solid bolt that extends deep into the door frame,
resisting forced entry and enhancing protection against break-ins. Our selection includes single-cylinder, double-cylinder, and heavy-duty
deadbolts that meet standard US door backset and thickness requirements.
Many of our deadbolts feature hardened steel construction, anti-saw bolt designs, and weather-resistant finishes to withstand heavy use and
external exposure. They are compatible with most residential doors and install easily with common tools, making them a great choice for new
builds, remodels, or home upgrades. For optimal security, we recommend pairing a deadbolt with a sturdy keyed-entry door knob or lever.

Deadbolts FAQ▾
Frequently Asked Questions
What is a deadbolt and why do I need one?
A deadbolt is a door locking mechanism that extends a solid bolt into the door frame when locked — it provides much stronger resistance
to forced entry than a simple latch lock, making it ideal for exterior doors, entry doors, and other doors where security matters.
What types of deadbolts are available?
Common types include single-cylinder deadbolts (keyed from the outside, thumb-turn inside) and double-cylinder deadbolts (key required both sides).
We offer a variety in our collection — choose based on your security needs, door placement, and local building codes.
Are deadbolts easy to install?
Yes — most of our deadbolts are designed for standard residential doors (common backset and thickness) and include all necessary hardware
(bolt, strike plate, screws). Installation can be done with basic tools and typically takes under an hour.
Should I pair a deadbolt with a keyed-entry knob or lever?
Absolutely. Combining a deadbolt with a keyed-entry knob or lever gives you dual protection — the latch provides convenience, and the deadbolt
adds resistance to forced entry. This is the recommended setup for exterior doors that need both security and ease of use.
