Locks & HardwareBuilt to Protect
Every security plan starts with the right lock on the right door. As Erie's Authorized Medeco Security Center, Interstate Security carries and installs some of the most pick-resistant, drill-resistant lock hardware available anywhere. From a simple rekey to a full high-security retrofit, our team has been getting it right since 1964.
Authorized Medeco Security Center
Factory-authorized to sell, install, and service the full Medeco product line.
Medeco locks have set the standard for high-security cylinders in North America for decades. Their patented rotating pin technology and restricted keyways make Medeco products extraordinarily resistant to picking, drilling, bumping, and unauthorized key duplication. Interstate Security is one of the few authorized Medeco dealers in the region, which means our customers get factory-backed installation, genuine Medeco parts, and the expertise that comes with factory training.
Whether you need to protect a single entry door at home or secure an entire commercial facility with a restricted master key system, Medeco offers solutions that most consumer-grade locks simply cannot match. Every Medeco key is controlled, so copies can only be made by an authorized dealer with proper identification and authorization. That level of key control is what separates true high-security hardware from off-the-shelf alternatives.
Our Lock Services
From standard residential hardware to commercial high-security installations, we handle every aspect of lock work.
Installation & Repair
New lock installation on interior and exterior doors, replacement of worn or damaged hardware, and repair of malfunctioning cylinders and mechanisms. We work with residential and commercial door types of all kinds, including mortise locks, cylindrical lever sets, and rim-mounted deadbolts.
Rekeying Services
Moving into a new home or office? Rekeying changes the internal pins of your existing locks so that old keys no longer work and only your new keys will operate the cylinders. It is a cost-effective way to restore security without replacing all of your hardware.
High-Security Systems
Medeco high-security cylinders, restricted keyway master key systems, and commercial-grade hardware for businesses, government facilities, and any property requiring the highest level of physical key control and forced-entry resistance.
Keyless Entry Systems
Electronic keypad locks and keyless entry solutions from Schlage and other top manufacturers. Ideal for rental properties, offices, and homeowners who want the convenience of code-based access without carrying a physical key.
Emergency Lockouts
Locked out of your home or business? Our technicians can get you back inside without damaging your door or lock. We use professional bypass techniques and non-destructive entry methods to restore access quickly and safely.
Maximum Security Deadbolts
Deadbolts that exceed ANSI Grade 2 requirements and deliver Grade 1 security features. These heavy-duty deadbolts provide superior resistance to kick-ins, prying, and forced-entry attacks, making them the right choice for high-risk entry points.
