When a regular lock is not enough
If any of these describe what you're dealing with right now, this is the service you need. Call with your situation and location - we'll confirm we can help before sending anyone out.
You Were Broken Into and the Lock Was Picked or Bumped
Standard locks can be defeated with tools anyone can buy online for $20. High-security locks use internal mechanisms that make picking and bumping virtually impossible.
Someone Copied Your Keys Without Permission
Standard keys can be duplicated at any hardware store or kiosk in 60 seconds. Our restricted keyways use patented blanks that only we can cut - and only with your authorization card.
Your Insurance Requires Better Locks
Some policies require UL-listed or Grade 1 hardware to maintain coverage for high-value inventory or equipment. We install the specific hardware your insurer needs to see.
You Have High-Value Items Behind a Standard Deadbolt
Jewelry, cash, firearms, sensitive documents, server rooms - if what's inside is worth more than a standard lock can protect, it's time to upgrade the hardware.
Describe your situation - we'll confirm the right service and come prepared.

High-Security Locks That Actually Stop Break-Ins
Standard locks from the hardware store can be picked, bumped, or drilled in under a minute with tools anyone can buy online. If you've been broken into - or you're protecting high-value assets - it's time for hardware that's engineered to resist real attacks. Kwikey Locksmith installs Medeco, Mul-T-Lock, and Abloy cylinders for businesses and homes across Delaware and nearby Pennsylvania.
Keys That Can't Be Copied Without Your Permission
The biggest security gap in most buildings isn't the lock - it's the keys. Standard keys can be duplicated at any hardware store or automated kiosk for a few dollars, with no questions asked. Our high-security locks use restricted keyways with patented blanks that are only available through authorized dealers. Every key copy requires your written authorization, so you always know exactly how many keys exist.
Brands That Professional Locksmiths Trust: Medeco, Mul-T-Lock, Abloy
Not all 'security' locks are created equal. We install the brands that have proven themselves against real-world attacks and independent testing: Medeco (rotating pins that defeat picking), Mul-T-Lock (telescopic pin-in-pin technology), and Abloy (disc-detainer mechanisms with no traditional pins to bump). We help you choose the right brand based on your specific threat, budget, and door hardware.

High-Security Locks FAQ
These are the questions people ask most before booking this service. If yours isn't here, call us - we'll answer it directly.
Are these locks really pick-proof?
No lock is theoretically impossible to pick, but high-security locks like Medeco and Mul-T-Lock are designed to resist expert manipulation for extended periods. For practical purposes, they stop the tools and techniques used in real-world break-ins.
What's an authorization card and why do I need one?
It's a unique card that comes with your lock system. Without presenting it, no locksmith can legally cut additional keys for your restricted keyway. It's how you maintain total control over who gets copies.
Can I put high-security locks on my house, not just a business?
Absolutely. Many homeowners install Medeco or Mul-T-Lock deadbolts on their front and back doors - especially after a break-in or if they have valuables, firearms, or a home office.
Do I need new doors to install these locks?
Usually not. High-security cylinders retrofit into most standard commercial and residential doors. We check compatibility during the site visit and let you know if any door prep is needed.
How much more do high-security locks cost compared to regular ones?
They cost more upfront than hardware-store locks, but they last significantly longer and eliminate the ongoing cost of rekeying after unauthorized key copies. We provide exact pricing during the quote.
