VVDI Super Chip vs Keydiy Super Chip

 For years, the Xhorse VVDI Super Chip XT27A has been the dominant, go-to multi-transponder for its versatility and reliability. This review, based on extensive testing with the Keydiy KDX4 tool, pits the new Keydiy Super Chip KD26 against the established XT27A to see if it’s a worthy competitor or a late arrival to the party.

First Look: Setup and User Experience

To use the KD26 with the KD-X4 tool, a firmware update to version 1.38 or higher is required. This update promises optimizations specifically for the KD26, including improved generation of 8A type chips and 4D decoding.

A key differentiator is the user workflow.

The XT27A is known for its straightforward process: you often select the target vehicle, and it generates the chip directly.

The KD26, however, frequently requires a two-step “pre-load” process. For many chip types, especially complex ones like the Toyota 72G (a 4D-80bit chip), you must first configure the KD26 to a general type (e.g., “4D 80bit”) and then go to a separate menu to generate the specific vehicle profile. This adds an extra layer of complexity and is less intuitive than the XT27A’s direct approach.

 

Performance and Compatibility

1. Chip Generation and Versatility

XT27A: Offers a mature, broad, and well-organized menu. It has extensive list for brands like Nissan, with many specific models listed. It reliably generates a wide array of chips without significant issues.

XT27A Supports generating:

• ID 11
• ID 12
• ID 13
• PCF7935- (ID33,40,41,42,43,44)
• PCF7936- (ID46)
• PCF7937
• PCF7938- (ID47)
• PCF7939- (ID49)
• PCF7946
• CR 48
• ID 4C 
• ID 4D- (ID60,63) 
• ID 4D (80) – (ID70,83, G)
• ID 4E- (ID64)
• ID 8A- (H)
• ID 8C
• ID 8E

 

KD26: It successfully generated common chips like the ID48 (TP23) and ID46 (7936) without issue. However, its menu for some brands (like Nissan) was noted as being less comprehensive (“a little poor”) compared to the XT27A. It also lacks some specific options, such as the “Circul Plus” for Chevrolet.

KeyDIY Super Chip D26 Supports generating:

• ID11
• ID12
• ID13
• 7935 (ID33)
• ID46 (PCF7936 / PCF7946)
• 8E / 7935 (40 / 41 / 42 / 43 / 44)
• ID46 (EX, PCF7937)
• ID46 (EE, PCF7947)
• ID47 (PCF7938)
• ID48
• ID49 (PCF7939V)
• ID4C
• ID44
• 80
• ID64
• 1D4E
• ID8A
• ID8C

2. Handling 4D Chips (Toyota, Chrysler, Mazda)
This is where the most significant differences and issues were found.

XT27A: Proven and stable. It correctly identifies and generates 4D chips like the ID64 for Chrysler/Jeep without problems.

KD26: Demonstrated instability and incorrect generation:

Incorrect Configuration: When generated for an ID64 (Chrysler/Jeep), the KD26 was sometimes misidentified by other tools as a 4C or a DST40 instead of a 4D chip.

Blank Data: The generated ID64 chip often had critical data pages (like User and Password) set to zeros, which would prevent it from working correctly in a vehicle without manual editing—a complex and error-prone process.

Blocking Issues: During testing, the KD26 occasionally became “blocked” when attempting to generate certain 4D types, requiring a reset function before it could be used again.

 

3. Physical Design and Price

XT27A: Is a known commodity, widely available, and has a very accessible price point.

KD26: Is reportedly being sold at a price premium over the XT27A

 

Based on this hands-on testing, the conclusion is clear:

Stick with the Xhorse XT27A.

The Keydiy KD26 arrives late to the market and offers no compelling advantages. In fact, it falls short in several key areas:

Less Mature Software: The requirement for a pre-load configuration and less intuitive menus make it slower and more complicated to use.

Performance Issues: Its unreliability with critical 4D chips like the ID64 makes it a risk for professional use.

Higher Price: It costs more than the proven and cheaper XT27A.

No New Capabilities: It doesn’t support any new vehicle protocols that aren’t already covered by the XT27A or other, more specialized chips like the AT1 (which can handle newer 4A-type chips).

For locksmiths and technicians who already own tools like the Xhorse Mini BBDI or Key Tool Max that support the XT27A, investing in the KD26 ecosystem (like the KDX4) is difficult to justify. The XT27A remains the more stable, cost-effective, and widely supported workhorse for the vast majority of jobs. The KD26 has significant maturing to do before it can be considered a viable alternative.

Xhorse FBS3 Key Benz W221 Keyless Not Working Solution

 Problem:

Making a spare proximity key for Mercedes Benz W221 using Xhorse VVDI MB tool.

But can’t get the Xhorse Smart Key (keyless go) to work with start/stop button. Works if I turn in EIS.
Tried different key tracks and all set to v041.
Also tried another new key. The original key works.

Solution:

Xhorse keyless key is not working on this car.
Xhorse doesn’t support before 09.
If car 2009 2008 doesn’t support vvdi mb smart key.
It just work on 2010 and up. Before 2009, keyless key is not available; only after 2010, w164, w166.

Only the original 08 key or CGDI 08 key will work.
cgdi ones they work better for this model.

You don’t have to use CGDI MB to program the Mercedes cgdi fobs. Any capable Mercedes programmer can do it.

NISSAN AutoAuth SGW is Available on TOPDON Diagnostic Tools

 Great news for all Topdon users! TOPDON is pleased to announce that our diagnostic tools are now officially certified to access NISSAN AutoAuth SGW, allowing full diagnostic access to modern NISSAN vehicles across North America.

Topdon diagnostic tools now support Nissan AutoAuth SGW unlock, giving you access to perform full diagnostics without restrictions. After unlocking it, you can: clear DTC, perform advanced ECU programming and coding, activate bidirectional control, etc.

Currently, you can try Nissan AutoAuth SGW unlock on TopScan, ArtiDiag 500/600 S/600 Elite/700/900 Lite, UltraDiag and Phoenix tools (Phoenix Lite, Phoenix Nano, Phoenix Plus, Phoenix Max, Phoenix Smart,  Phoenix Xlink etc) 

What is NISSAN AutoAuth SGW Access?

 

NISSAN implemented the Secure Gateways(SGW) in its new-generation models to strengthen cybersecurity and protect vehicle electronic systems. The SGW acts as a protective barrier, preventing unauthorized access to critical ECUs and restricting diagnostic tools to basic read-only functions.

Now NISSAN US is using the Automatic Authentication Authority (AutoAuth) to manage user accounts for access to SGW vehicles.

 

Why is Unlocking the NISSAN AutoAuth SGW Necessary?

 

Before unlocking:

Without unlocking the SGW, diagnostic tools can typically offer full OBD2 functionalities, allowing for basic diagnosis such as code reading, reading ECU information and monitoring live data.

 

After unlocking: 

By unlocking the NISSAN secure gateway, North American users can perform complete and advanced diagnostics on NISSAN vehicles including ECU programming, ECU coding, active tests, maintenance services, immobilizer functions and more.

*The specific functions available depend on the diagnostic tool’s features.
