KEYDIY – KDX4 – Universal Key Programmer

Description

The KDX4 (KD-X4) is a high-end, all-in-one locksmith device engineered for automotive key programming, remote generation, and chip operations. It combines recognition, generation, copying, programming, and matching functions in a single unit, and can operate independently or connect to tablets, phones, or PCs — letting locksmiths choose the workflow mode they prefer.

It’s designed to be user-friendly yet powerful, offering broad model coverage, regular updates, and industry-leading features.

Key Features & Capabilities

• Remote Generation — Supports over 5,600 remote control program templates.

• Remote Copying & Simulation — Capable of copying remotes for 50+ car models, simulate smart/remote keys, and replicate keyless remotes.

• Frequency Detection — Detects frequencies including 315 MHz, 433 MHz, 467 MHz, 868 MHz, 902 MHz, and 2.4 GHz.

• Anti-Theft Chip Recognition & Copying — Supports numerous chip types (e.g. MLB, 5C, 46, 47, 48, MOB48, 4D, 4C, 8A, 6A, 4A, 8E, 8C, 13, 11, 12, 7935X, 49, and AUDI5 33/40-44).
