How to Tell Xhorse Old or New Smart Remotes?

 Xhorse VVDI Remotes are constantly being upgraded with the development of chips and technology. For certain models are only workable for old vvdi remotes; for some latest models are restricted to new vvdi remotes.  In the process of updating, a little part of keys can be only generated via old types keys of smart keys.

Error  example “The latest remote no support (868.902 frequency), please use old remote (before June 2000) to generate.”

Faced with such a situation, it’s very helpful to learn to distinguish the Xhorse smart remotes.

 

 

Method1. Check Circuit Board

New VVDI Remotes: Remote chip with 2-sides pins.

 

Old VVDI Remote (2 types):

1. Remote chip with 4-sides pins.
2. 2-sides pins chip + 6-pins component.

The old type and new type vvdi smart key difference is:

The new model does not support 868.902, others are the same.

If you feel that it is troublesome to disassemble the key shell and take out the circuit board, you can also use key tool series to check.

 

Method2. Check on Xhorse Key Tools

This way is available on VVDI Key Tool Plus Pad, MINI KeyTool, Key Tool Max to detect remote version.

 

Query path:

Special functions >> VVDI remote function >> Detect remote

Put the smart remote into coil, then press detect.

And the result version will tell you how to distinguish:

 

 

New VVDI Remotes: V2.0 or above.

Old VVDI Remotes: below V2.0

How To Use VVDI MB TOOL OBD Clip?

 We may find that it is seldom used the VVDI MB Tool OBD Clip while programming Mercedes. In general, we more often use the OBD cable connector instead. So when and how to use the OBD clip?

 

When programming Benz 204/207 with directional lock on car, it’s not able to read data with VVDI MB Tool by OBD directly. That’s because data will be interfered due to OBD connection. That’s why locksmiths always remove directional lock on bench to read immo data or match simulator.

 

Can we program Benz 204/207 without wiring harness on car?

The answer is yes.

 

By reason of filtration and interference from other car modules, it’s failed to read immo data by OBD. But we can bypass the interference through connecting OBD communication line on device to directional lock straightway. That’s what the VVDI MB OBD Clip can do: connect to directional lock.

 

How to use VVDI MB OBD Clip?

1. Break open the communication line of directional lock;
2. Clamp to communication line.

Note:

* DO NOT disconnect plugs of directional lock & ELV Emulator.

* Clamp to the corresponding line for red marked pin.

* Need to break wire skin.

It’s recommended to use the way in case emergency without any EIS/ELV Test Lines.
