Hi everyone,

I am reaching out to Razer Support and the community regarding an out-of-the-box hardware failure on a brand new Razer BlackWidow V4 X.

The keyboard was purchased on October 6, 2026 (06:35 AM) at the Dufry / Avolta Duty Free shop at Rio de Janeiro Airport (GIG) by my partner as a gift for me. I have the official purchase receipt/proof of purchase readily available.

Device Information

  • Model: Razer BlackWidow V4 X

  • Serial Number (S/N): (removed for security purposes)

  • Purchase Date: October 6, 2026

  • Purchased From: Dufry / Avolta (Rio de Janeiro Airport, Brazil)

  • Proof of Purchase: Original store receipt on hand (issued in my partner's name)

  • Current Location: Argentina

Issue Description

From the very first time I plugged the keyboard into my workstation and initialized it with Razer Synapse, the device has exhibited severe key ghosting and registration issues.

Specifically:

  • Keystrokes frequently fail to register when typing at normal speeds or pressing multi-key combinations.

  • Key signals either drop entirely or fail to trigger proper scan codes, which is completely abnormal for a gaming mechanical keyboard with dedicated N-key rollover / anti-ghosting matrices.

  • The issue persists across different USB ports, without USB hubs, and across clean environments (with and without Razer Synapse running in the background), pointing directly to a factory hardware defect on the controller/PCB matrix.

Request

Given that the device is brand new, well within the manufacturer's warranty window, and I am based in Argentina:

  1. I would like assistance in opening an official RMA case for a unit replacement.

  2. I would like to know the standard procedure and logistics for warranty replacements for users located in Argentina.

I can immediately provide photos of the serial number label, a digital scan of the original receipt, and short video recordings documenting the ghosting behavior if needed by the support team.

Thanks in advance for your assistance
