Rekeying vs. Lock Replacement
Understanding which service fits your security needs and budget.
Lock Rekeying
The Cost-Effective Security Reset
Rekeying is the process of changing the internal pins within your existing lock cylinder so that old keys no longer work and a new key is required. This is the preferred method for move-ins and lost keys when the hardware is still in good condition.

Expert Verdict
CHOOSE REKEYING IF:
The lock is mechanically sound but access needs to be revoked for previous tenants or lost key owners.
CHOOSE REPLACEMENT IF:
Hardware is tarnished, jammed, or you desire an upgrade to smart-lock technology or high-security ANSI Grade 1 deadbolts.
Complete Lock Replacement
Sometimes a fresh start is the only way to ensure total peace of mind. Our locksmiths carry a full inventory of professional-grade hardware including Schlage, Kwikset, and Medeco systems. We don’t just swap locks; we reinforce the door frame, ensure proper strike plate alignment, and test every mechanism for 100% reliability.
Residential Rekeying & Safety
Your home’s security is only as strong as the keys in circulation. If you’ve just moved into a new property in Maryland, you have no way of knowing how many copies of your front door key exist.
Deadbolt Upgrades
Upgrade to ANSI Grade 1 high-security deadbolts that resist bumping, drilling, and prying.
Our residential locksmiths are experts in the architectural integrity of MD homes, ensuring that security upgrades never compromise your home’s curb appeal.
Commercial Security Upgrades
Managing access for multiple employees requires a sophisticated approach. Multi Locksmith LLC provides scalable commercial security for offices, retail hubs, and industrial facilities.

The Science of Lock Security
Understanding ANSI Grades
The American National Standards Institute (ANSI) provides the industry standard for lock durability and security. When we perform a lock change, we recommend specific grades based on your vulnerability:
- Grade 1 (Professional/Heavy Commercial): The highest level of security. Tested to withstand 800,000 cycles and high-impact physical attacks. Ideal for exterior commercial doors and high-crime residential areas.
- Grade 2 (Residential/Light Commercial): The standard for most homes. Designed to withstand 400,000 cycles and moderate impact. Great balance of cost and security for residential side doors.
- Grade 3 (Basic Residential): Minimum security. Mostly used for interior doors like bedrooms or closets. We rarely recommend these for main points of entry.
The Rekeying Process: Behind the Cylinder
Our technicians use precision-calibrated tools to disassemble the lock cylinder. Inside, a series of top pins and bottom pins must align at the ‘shear line’ for the lock to turn. During rekeying, we discard the old pins and insert new ones of specific heights that match a brand-new key configuration. This mechanical reset is permanent and just as secure as buying a new lock, provided the cylinder itself isn’t worn out.
We also check for ‘master pinning’ during this process. In many apartment complexes or commercial buildings, locks are set up to accept two different keys. If you value privacy, we can remove master pins to ensure your individual key is the only one that can operate the lock.

Frequently Asked Questions
Can all locks be rekeyed?
Nearly all traditional pin-and-tumbler locks can be rekeyed. This includes major brands like Schlage, Kwikset, Yale, and Baldwin. Some specialized European profile cylinders or high-security proprietary systems may require factory-specific kits, which our team carries on-site.
How long does a lock change take?
A standard residential lock change or rekeying is completed efficiently by our skilled technicians. For commercial buildings with multiple access points, we can deploy a team to secure the entire facility in a matter of hours.
Is rekeying cheaper than replacement?
Yes, significantly. Since rekeying only involves changing small internal components (pins) rather than the entire hardware housing, you save on material costs. Rekeying is typically 50-70% less expensive than buying new high-quality hardware.
Will the locksmith damage my door?
Never. As licensed professionals, we use non-destructive entry and installation methods. We ensure all holes are perfectly aligned and hardware sits flush against the door, maintaining both security and aesthetic integrity.
