Glovebox Replacement Button Lock For Mercedes GL X166 - 2012 to 2015

Glovebox Button Lock Replacement for Mercedes-Benz GL X166 — Snap-In Fix for a Known Failure

Direct replacement glovebox latch handle for the Mercedes-Benz GL (X166). The full-size GL is a family hauler that sees the glovebox opened and closed dozens of times a day — enough daily stress to crack the thin factory plastic, jam the spring mechanism, or snap the chrome button entirely. This part replaces OEM part number A1666800491 and restores original click-and-release function without any tools or interior disassembly.

This glovebox latch handle replaces OEM part A1666800491 and fits the following models:

Why the GL X166 Glovebox Latch Fails

The X166 platform glovebox latch is injection-molded from a thin plastic compound that becomes brittle through years of heat cycling inside the passenger cabin. On the GL — which is often the primary family vehicle with high daily use — the button sees more open/close cycles than on most platforms. The spring mechanism weakens first, making the button feel stiff or unresponsive. Then the housing cracks or the chrome trim separates from the base. At that point, the glovebox either stays open permanently or requires two hands and a specific technique to operate.

This replacement is manufactured to OEM specifications (A1666800491) and clips directly into the original mounting position — same click-open, secure-close action as the factory part when the car was new.

Key Features

• OEM-spec replacement — matches Mercedes-Benz part number A1666800491 for precise fit and function
• Durable ABS and PC construction — improved resistance to heat-related brittleness versus the original
• Chrome-finish button — matches factory interior trim for an invisible repair
• Smooth latch mechanism — clean click-open, secure hold-closed, no jamming or play
• Direct snap-in fit — no modifications, no adhesive, no drilling

Two-Minute Installation

No tools required. No dashboard removal. No dealership visit.

1. Open the glovebox and remove the old latch by releasing the retaining clips from behind the glovebox door panel
2. Snap the new latch into the same mounting position — it clicks into place
3. Test the button — press to open, push the door to close and latch

What's Included

• 1x Glovebox latch handle assembly (chrome button with mounting housing)
