Deadbolt Installation in Baltimore, MD
Stronger door security with professional deadbolt installation for homes and businesses.
Deadbolts provide significantly more resistance to forced entry than spring latches alone. If your exterior doors don't have a deadbolt — or have an older, worn one — installation is a straightforward upgrade.
Baltimore Locksmith installs single-cylinder and double-cylinder deadbolts on residential and commercial doors throughout Baltimore. We work with standard hardware as well as higher-security options.
All deadbolts are installed with proper alignment and tested before we leave to make sure the bolt extends and retracts smoothly and the door closes securely.
Deadbolt Installation FAQs
What's the difference between a single-cylinder and double-cylinder deadbolt?
A single-cylinder deadbolt uses a key on the outside and a thumb turn on the inside — the most common type for residential doors. A double-cylinder requires a key on both sides, which adds security but means you need a key to exit. Double-cylinder locks are sometimes used on doors with glass panels near the lock.
Can you install a deadbolt on my existing door without major work?
In most cases, yes. Standard residential doors are pre-drilled for deadbolts at a standard height. If your door doesn't have a hole, we can drill it. We'll assess your door before starting and let you know what's involved.
How much more secure is a deadbolt compared to a knob lock?
Significantly more secure. Knob locks can often be defeated with simple forced entry techniques. A properly installed deadbolt with a reinforced strike plate is much more resistant to kicking, prying, and picking.
Can you replace an old or worn deadbolt?
Yes. If your existing deadbolt is stiff, worn, or no longer functioning reliably, we can replace it with new hardware. We'll remove the old lock and install the new one in the same opening.
Do you install deadbolts on commercial doors?
Yes. We install deadbolts on commercial doors as well as residential. For commercial applications, we can also recommend higher-security options appropriate for business use.
