Description

Product: Hyosung Universal Bezel / Fascia Key

Condition: New Application: Upper Cabinet / Top Fascia Access

Technical Overview

The Hyosung Bezel Key is a standardized mechanical access tool required for opening the upper cabinet (top hat) or front fascia of Nautilus Hyosung retail ATMs. Unlike the vault key, which secures the cash assets, the bezel key provides access to the service area containing the mainboard, receipt printer, card reader assembly, and LCD display.

This key operates the cam lock or plunge lock mechanism located on the side or rear of the upper enclosure, allowing the technician to unlatch and hinge open the fascia for First Line Maintenance (FLM) and Second Line Maintenance (SLM) tasks.

Operational Utility

For an ATM technician, this key is an essential tool for daily operations. Without it, the upper cabinet remains inaccessible, preventing the resolution of common errors.

• Routine Maintenance: Required to replenish receipt paper and clear printer jams.
• Diagnostics: Necessary to access the Operator Panel (OP) board or mainboard for hard resets and diagnostic switches.
• Component Replacement: Provides the initial access point needed to replace the LCD, keypad, or card reader assembly.

Compatibility and Cross-Platform Standardization

This key features a specific cut profile that Hyosung standardized across multiple generations of retail ATM models. This backward and forward compatibility allows field technicians to carry a single key for a wide fleet of machines.

Verified Compatible Models:

• MB Series: MB1000, MB1500
• NH Series: NH1800, NH1800CE, NH1800SE, NH2700, NH5000
• Halo Series: Halo, Halo II

Service Recommendations

• Key Management: It is industry best practice for ATM operators and route technicians to carry backup bezel keys. Loss of this key during a service call results in an inability to perform even basic tasks like paper loading.
• Lock Maintenance: If the key encounters resistance when turning, do not force it, as the keyway is often made of softer brass or die-cast zinc and can shear. Instead, apply a dry graphite lubricant to the lock cylinder.
• Wear Indication: Inspect keys regularly for rounded teeth or stress fractures near the head. A worn key may fail to engage the tumblers correctly, leading to “jiggling” requirements or failure to unlock.
