High Security Locks for Memphis Businesses — Abloy, Medeco, Mul-T-Lock

Standard lock cylinders are designed for standard security. If your Memphis business handles valuable inventory, sensitive documents, or high-traffic access, standard locks are an inadequate defense. High security locks — specifically Abloy, Medeco, and Mul-T-Lock cylinders — are engineered to resist picking, drilling, bumping, and unauthorized key duplication. They’re the locks you install when you need to know that your doors will actually protect what’s behind them.

Southern Locksmith Solutions is an authorized dealer and installer of Abloy, Medeco, and Mul-T-Lock high security lock systems for commercial properties throughout the Memphis metro area. We design, install, and service high security key systems that give you the level of physical security your business deserves — and the key control you need to keep unauthorized copies from circulating.

What Makes a Lock “High Security”?

High security locks differ from standard commercial locks in several critical ways:

Restricted keyways. The key profile is patented and controlled. Only authorized key blanks can be ordered through the manufacturer’s distribution network, and duplication requires proof of authorization. Standard key blanks from a hardware store won’t fit.
Anti-pick pin designs. High security cylinders use complex pin arrangements — side pins, dimple pins, mushroom pins, and other anti-manipulation features — that make traditional lock picking extremely difficult.
Drill resistance. Hardened steel inserts, drill plates, and other anti-drill features protect the cylinder core from drill attacks.
Key control. The manufacturer maintains strict control over who can order keys and from where. This is the single most important feature of a high security system — it prevents unauthorized key duplication at the source.
Higher pick resistance ratings. Independent testing facilities rate high security cylinders for pick resistance, often achieving ratings far above standard commercial cylinders.

High Security Brands We Install

Abloy. Finnish-designed high security cylinders that use a disc tumbler mechanism instead of traditional pin tumblers. Abloy cylinders are known for exceptional durability, pick resistance, and freeze resistance (important for exterior doors exposed to Memphis winter conditions). Abloy’s key control program is one of the most robust in the industry — keys are serialized and tracked through the manufacturer’s authorization system. Widely used in institutional, industrial, and high-traffic commercial applications.

Medeco. American-made high security cylinders with a reputation for unmatched security. Medeco cylinders use a combination of pin tumblers and side bars, with keys that feature vertical dimples and angular cuts. Medeco’s key control system is equally rigorous — keys are patented and restricted, requiring proof of authorization for duplication. Medeco is the go-to brand for government facilities, financial institutions, and any application where maximum physical security is required.

Mul-T-Lock. Israeli-designed high security cylinders that combine pin tumblers with a disc tumbler mechanism for dual-layer protection. Mul-T-Lock keys feature a distinctive profile that’s difficult to replicate without authorization. Mul-T-Lock is known for its versatility — offering a wide range of cylinder types (deadbolt, mortise, rim, tubular) in its high security line, making it a popular choice for businesses that need to standardize on one high security brand across their entire property.

When Your Memphis Business Needs High Security Locks

High-value inventory facilities. Warehouses, distribution centers, and storage facilities along the I-40 corridor that handle valuable goods need high security locks on their exterior doors, loading dock entrances, and interior secure areas.

Financial institutions. Banks, credit unions, and cash-handling businesses in Memphis and the tri-state area require high security locks that meet industry security standards and insurance requirements.

Healthcare facilities. Hospitals, medical offices, and pharmaceutical storage areas need high security locks on medication storage, records rooms, and equipment areas.

Government and municipal buildings. City offices, courthouses, and public facilities in Shelby County and surrounding areas require high security locks that meet government security specifications.

Multi-tenant commercial buildings. Office buildings, apartment complexes, and retail centers in Germantown, Collierville, and Cordova need high security locks that prevent tenants or former tenants from creating unauthorized copies of master keys.

Retail storefronts. High-traffic retail locations on Poplar Avenue, Elvis Presley Boulevard, and other Memphis commercial corridors benefit from high security locks on their entrance doors and stock rooms.

High Security Key Control

The real power of a high security lock system isn’t just the physical security of the cylinder — it’s the key control. Here’s how high security key control works:

Patented keyways. The key profile is protected by patent, meaning no unauthorized key blank manufacturer can produce compatible keys. You can’t walk into a hardware store and get a high security key cut.

Authorized key distribution. Key blanks and duplication are only available through the manufacturer’s authorized dealer network. Your locksmith must be authorized by the manufacturer to order keys for your system.

Proof of authorization. To duplicate a high security key, you must provide proof of authorization — typically a letter from the system administrator or property owner. This prevents former employees, contractors, or unauthorized parties from making copies.

Key tracking. Many high security systems maintain a record of who has been issued each key, when it was issued, and when it was returned. This audit trail is essential for property managers, building owners, and facility administrators.

High Security Lock Installation Process

1. Security assessment. We evaluate your facility’s current security posture, identify vulnerable entry points, and recommend the appropriate high security lock types for each application.

2. System design. We design a high security key system that matches your organizational structure — master key hierarchies, change keys, sub-master keys, and individual cylinder keys — using your chosen high security brand(s).

3. Installation. We install the high security cylinders in all designated door hardware — replacing existing cylinders with new high security equivalents, ensuring proper alignment and operation.

4. Key system programming. We program the master key hierarchy, cut all keys through the manufacturer’s authorized distribution channel, and establish your key control records.

5. Training and documentation. We provide your property management team with a complete key system documentation package, including key lists, authorization procedures, and contact information for future key orders.

High Security Lock Maintenance

Key replacement. If a high security key is lost or stolen, it can be replaced through the authorized key control system. The lost key is flagged in the system, and if it’s ever presented for duplication, the dealer is notified.

Cylinder rekeying. When you need to change the key combination of a cylinder (after an employee departure, property sale, or security breach), we rekey the cylinder through the manufacturer’s authorized service network.

System expansion. Adding new doors to your high security system is straightforward — we order new cylinders and keys through the manufacturer’s system and integrate them into your existing master key hierarchy.
