Autel IM608S II vs XTOOL AutoProPAD G3: Key Differences

1. Different Product Positioning and Core Design Philosophy

The Autel IM608S II is positioned as:

"An integrated professional tool for full-function diagnostics + advanced key programming"

It is essentially a high-end vehicle diagnostic tool that integrates very comprehensive IMMO/key programming capabilities. It is aimed at automotive technicians, general repair shops, and users who need full-system diagnostics and coding.

The XTOOL AutoProPAD G3 Evolution has a more specific positioning:

"A professional locksmith-grade tool centered on key programming, EEPROM/MCU"

The G3 Evolution's design philosophy revolves around chips, EEPROM, MCU, and pre-written key data. Diagnostic functions are only auxiliary, primarily targeting automotive locksmiths and technicians specializing in anti-theft and key services.

Autel IM608S II Product Introduction

2. Differences in Hardware Configuration and User Experience

In terms of hardware, the IM608S II prioritizes high performance and portability:

• Uses a Qualcomm octa-core processor, 128GB storage, and runs smoothly overall.
• 8-inch 1920×1200 high-resolution screen for clear display.
• 15000mAh large battery for long-term operation without relying on a power source.
• Weighs only about 1.58kg, making it easier to carry and operate outside the vehicle.

The G3 Evolution, on the other hand, is more of a "desktop locksmith device":

• Larger screen (10.1 inches), but lower resolution.
• Battery capacity is only 5000mAh, making it more dependent on charging.
• The entire device weighs about 3.9kg, which is not ideal for prolonged handheld use.
• The advantage is the wireless Wi-Fi VCI, which is more flexible in a workshop environment.

Conclusion:

If you frequently move between different vehicles and need portability and long battery life, the IM608S II is more suitable;

If you mainly perform key and chip operations at a fixed workstation, the G3's size and wireless capabilities are not a problem.

3. Differences in EEPROM/MCU Capabilities

This is one of the most crucial distinguishing factors between the two devices.

Autel IM608S II:

• EEPROM/MCU operations are performed via the XP400 Pro external programmer.
• Supports common tasks such as EEPROM, MC9S12, ECU, and infrared keys.
• More focused on a "OBD first, chip removal as a supplement" usage logic.
• For most modern vehicles, key and immobilizer operations can be completed directly on the vehicle.

However, it's important to note:

The IM608S II's EEPROM capabilities are more "sufficient, general-purpose, and standardized," rather than extreme in-depth functionality.

Autel IM608S II EEPROM Capabilities

XTOOL AutoProPAD G3 Evolution:

• This device emphasizes direct EEPROM/MCU read/write capabilities.
• Supports 440+ EEPROM component types.
• Features an EEPROM slot and a transponder slot.
• With the KC100 module, advanced key pre-writing is possible.
• Offers more advanced support for systems such as VW fourth/fifth generation immobilizers, BMW CAS, Fiat, and Land Rover.

Conclusion:

If you frequently need to remove ECUs, read/write chips, and perform advanced pre-coding, the G3 Evolution is clearly superior;

If you prefer to "avoid disassembly whenever possible," the IM608S II's workflow is more user-friendly.

4. Key Programming and IMMO Function Orientation

Both support common IMMO functions, such as: PIN code reading, All Key Lost, Key learning and deletion and Immobilizer data backup and restoration.

However, the logic differs:

The IM608S II emphasizes:

• High success rate for new models and mainstream American/Japanese/European vehicles
• Direct key generation, matching, and learning via OBD
• Smart Mode / Expert Mode guided operation

The G3 Evolution emphasizes:

• More suitable for locksmiths to "target specific systems"
• More advantageous for older, non-OBD-friendly vehicles
• EEPROM/MCU programming itself

The Autel IM608S II and AutoProPAD G3 are both powerful key programming tools

5. Significant Differences in Diagnostic Capabilities

This is where the two tools are not comparable.

The Autel IM608S II is a complete professional diagnostic tool that supports full system diagnostics, ECU coding, and bidirectional control (Active Test), and offers over 40 common maintenance service functions. It is capable of handling daily maintenance, fault diagnosis, and programming tasks, and is not limited to key-related services.

In contrast, the XTOOL G3 Evolution's diagnostic functions are primarily auxiliary, lacking full ECU coding and bidirectional control capabilities. It is more of a "key programming tool + simplified diagnostics" device, making it unsuitable as a primary diagnostic tool.

6. Vehicle Coverage and Usage Scenarios Differences

IM608S II:

• Covers almost all mainstream American, Japanese, and European models
• More comprehensive support for modern vehicles and OBD key programming
• Limited Tesla support, but significant advantages for traditional fuel/hybrid vehicles
• More suitable for auto repair shops requiring a multi-purpose device

G3 Evolution:

• In-depth support for advanced European anti-theft systems
• More user-friendly for older models (e.g., 1997–2007 Honda/Toyota/Lexus) using EEPROM methods
• More suitable for locksmiths and users specializing in key and anti-theft services

Autel IM608S II wide vehicle coverage

7. Updates, Subscriptions, and Long-Term Costs

• IM608S II: 2 years of free updates, lower long-term cost
• G3 Evolution: 1 year of free updates, subsequent renewals required

For professional users who use the device frequently over the long term, the update cycle is also a significant cost factor.

Conclusion

In summary, the Autel IM608S II and XTOOL AutoProPAD G3 each have their own strengths. The IM608S II, with its comprehensive diagnostic functions, powerful system coverage, and extensive maintenance services, performs more like a true flagship diagnostic device, while also possessing advanced key programming capabilities.

The G3 Evolution, on the other hand, specializes in EEPROM/chip-level programming and key data processing, making it more suitable for users who specifically focus on key and immobilizer services.

Ultimately, the choice depends on your work needs: if you need a versatile diagnostic and programming tool, the IM608S II is more recommended; if your focus is on chip reading and writing and key programming challenges, the G3 Evolution has its unique advantages. Hopefully, this comparison will help you make the best choice for your needs.
