AGB High-Security Profile Cylinder Key in Nickel-Plated Steel

Type

Functional Hardware Attachment / Key

Maker

Alban Giacomo SpA (AGB), a leading Italian manufacturer of hardware for windows and doors founded in 1947, recognized for high-security locking systems.

Material

Nickel-plated steel or nickel-silver alloy. Note: This is an industrial hardware item and contains no sterling silver or precious metal content.

Dimensions

Length approximately 60mm; Weight approximately 15-20 grams. Standard domestic key sizing.

Description

A utilitarian Italian-made cylinder key mounted to a teal plastic folding accessory. While it possesses a 'silvery' metallic appearance common to hardware, this is an industrial tool made of nickel-plated alloys designed for durability and friction resistance in door locks, rather than aesthetics or bullion value.

Key Features

Distinctive AGB branding, 'MADE IN ITALY' strike, five-pin biting profile, and integration with a folding plastic protective sleeve.

Material & Composition

Nickel-plated steel or nickel-silver alloy. Note: This is an industrial hardware item and contains no sterling silver or precious metal content.

Finish & Decoration

Industrial nickel plating with a matte/brushed finish on the head and a polished finish on the bitted blade. Decoration is limited to die-stamped manufacturer branding.

Hallmarks & Stamps

Stamped with the 'AGB' logo in a rectangular border and the capital block letters 'MADE IN ITALY'. No silver purity hallmarks are present as this is a base metal item.

Construction Details

Industrial die-struck and machined. The key is blanked from sheet metal, then precision milled to create the warding and bitting patterns.

Functional Features

Precision milling for cylinder alignment, shoulder stop for depth positioning, and an ergonomic trapezoidal head for torque application.

Handle & Grip Details

The key is mounted to a turquoise thermoplastic folding fob or multi-tool case, featuring a pivot mechanism and a wire split-ring for attachment.

Craftsmanship Details

High-quality industrial machining. The bitting is crisp and the stamping is deep and legible, indicating high-volume precision manufacturing.

Authentication Indicators

Clearly defined AGB trademark and manufacturing origin stamps consistent with genuine Alban Giacomo hardware. Absence of silver hallmarks confirms it is standard hardware.

Origin & Manufacturing

Made in Italy, likely in the Romano d\'Ezzelino production facilities of Alban Giacomo SpA.

Era & Period

Modern Era (late 20th to 21st century). The design is utilitarian, reflecting contemporary European industrial standards.

Age Estimate

Circa 2000-present. The branding and plastic housing style suggest modern mass production.

Cultural Significance

Represents the standard for European security hardware and the prevalence of Italian precision engineering in everyday domestic objects.

Condition Notes

Very Good. The nickel plating shows minor surface scratches consistent with use. The plastic housing shows slight scuffing. No structural deformation of the blade.

Value Estimate

$5 - $15 USD. The value is strictly functional as a replacement key or for the lock it operates; it has no precious metal scrap value.

Care & Maintenance

Keep dry to prevent oxidation of the base steel if plating is scratched. Lubricate locks with graphite rather than oil to maintain key function.

Similar Pieces

Silca, JMA, or Errebi key blanks. These are functional competitors but lack the specific AGB proprietary branding.

Interesting Facts

AGB is one of the few global hardware firms that controls the entire production cycle from raw metal to finished lock system in Italian factories.
