KEYDIY KD-X4 vs. KD-X6 Standard vs. Full: What Is the Difference?

 If you are choosing between KEYDIY KD-X4 and KD-X6, the decision mainly comes down to how often you need advanced functions.

KD-X4 is enough for basic key, remote, chip, and common IMMO work. KD-X6 Standard Version gives you the newer platform and built-in DoIP/MLB/MQB48 functions, while allowing you to pay for advanced functions when needed. KD-X6 Professional/Full Version is the better fit for locksmiths who use advanced functions regularly.

KD-X6 is scheduled to be available from OBDExpress.co.uk in December 2026.

What Does KEYDIY KD-X6 Add?

KD-X6 keeps the main functions of KD-X4 key programmer but changes the way some operations are performed.

1. No PC or Phone Required for Supported Operations

Unlike the previous workflow, KD-X6 can perform supported key programming and IMMO operations directly from the device.

2. DoIP Is Built In

KD-X6 includes built-in DoIP, so users do not need a separate DoIP adapter for supported vehicles.

3. MLB and MQB48 Are Integrated

The KD-MP MLB and MQB48 functions are integrated into KD-X6.

For supported operations, there is no need to connect a separate KD-MP unit.

4. Mercedes-Benz FBS3

KD-X6 supports FBS3 Add Key and AKL functions on supported Mercedes-Benz vehicles.

FBS4 and FBS5 functions are still being developed.

5. Cloud-C Remote

KD-X6 also supports Cloud-C remote functions, adding another option for supported remote programming jobs.

The Real Difference between KD-X6 Standard and Full

Both versions use the KD-X6 platform, so the main difference is not the basic device itself. It is the way advanced functions and accessories are provided.

• Standard Version

With Standard, you get the core KD-X6 functions.

If you occasionally encounter a job requiring an advanced function, you can purchase the required activation, KD Coins, or adapter separately.

This makes sense if advanced functions are not part of your daily work.

• Professional/Full Version

The Professional/Full Version is aimed at locksmiths who need more functions on a regular basis.

The applicable advanced functions are included in the package, and it also includes two important adapters:

• KD-MOTO Adapter
  Used for supported motorcycle key programming.
• DB25-FBS3 Adapter
  Used for supported Mercedes-Benz FBS3 operations.

With the Standard Version, these adapters are purchased separately when required.

Which One Makes More Sense?

• Go with KD-X4 5-in-1 key programmer if your jobs are mostly basic key programming, remote generation, chip functions, and standard IMMO work.
• Choose KD-X6 Standard if you want the newer hardware and built-in DoIP/MLB/MQB48 but do not want to pay for every advanced function upfront.
• Choose KD-X6 Professional/Full if you are a full-time locksmith or run a busy workshop where advanced programming functions are used frequently.

The best choice depends less on the device name and more on the functions you actually use in your daily work.

Hyundai & Kia Key Tool: Eoneboss HK001 vs. HK002 vs. HK003

 Eoneboss HK001, HK002, and HK003 mainly differ in supported smart-key types, key operations, and wired vs. wire-free workflow. HK001 is for 46/47/49/4A keys and adds cloning, HK002 is for 8A keys with PIN-code reading, and HK003 is for 6A keys with wire-free unlocking and wired same-part-number key generation.

HK001 vs. HK002 vs. HK003: Core Comparison

All three support Hyundai and Kia smart keys with part numbers starting with 95440.

Key Buying Differences

HK001: 46/47/49/4A keys + cloning

HK002: 8A keys + PIN-code reading

HK003: 6A keys + wire-free unlocking + same-part-number key generation

Cloning: HK001 only

PIN-code reading: HK002 only

Wire-free one-click unlocking: HK002 and HK003

Same-part-number key generation: HK001 and HK003, both wired

No adapter: HK002

Direct use after operation: Only cloned keys from HK001; generated and unlocked keys require vehicle programming

Which One Should You Buy?

• Choose HK001 for 46/47/49/4A keys or when cloning is required.
• Choose HK002 for 8A keys, especially when PIN-code reading is needed.
• Choose HK003 for 6A keys when you need wire-free unlocking and same-part-number key generation.

Quick Recommendation by Key Type

46 / 47 / 49 / 4A → HK001
8A → HK002
6A → HK003

Need cloning → HK001
Need PIN-code reading → HK002
Need 6A wire-free unlocking → HK003
