Transponder Tools

Overview

The Transponder Tools section of the software allows the more advanced user to manually write

data onto the transponder. This may be done either as part of research into the world of

EEPROM/MCU modules or to manually create a key with a known set of data - needless to say that

most locksmiths won’t ever need to use this sort of function.

Please note that it is very easily to lock a transponder if you’re unsure as to what you are doing.

Using The Tools

To start using the tools, click on the option on the main menu:

Touchclone will ask you to insert the transponder you want to read or write. This software will then

load up the relevant tool.

ID46 Transponder Tools

This is the tool for custom reading and writing to an ID46 transponder. Clicking read will load in the

data from the transponder inserted into Touchclone:

Frequency: shows you the method of encoding used (this is equivalent to the language of the

transponder).

Mode: shows the method of authentication the transponder uses. If a value is used that Touchclone

doesn’t know or has been told about then this will read as locked as the software cannot tell the

difference.

On the left hand side of the screen you have the data to be written to or read from the transponder.

The Write buttons will allow you to write this data to the transponder using the authentication data

specified (please see section later).

Clicking on the Extended button will bring up the extended transponder information screen. Clicking

on the individual options will change the value in the first block. This can then be programmed to the

transponder by clicking on the Write button.

In order to specify the authentication data to be used when reading and writing, click on the

relevant Mode in the bottom right hand corner. This will then bring up the boxes where you can

enter your custom data. For Crypto mode there are 6 bytes of data to be entered and can be

reverted back to the default values by clicking the Default button.

5


The same can also be done in Password mode, where only 4 bytes need to be entered. Again, you

can revert back to the default values by clicking the Default button.

4D Transponder Tools

This is the tool for custom reading and writing to an ID4D transponder. Clicking read will load in the


You can use the lock and write buttons on each line to write data and lock the individual pages.

7


As well as writing, the transponder tool allows you to perform a challenge/response function against

the transponder. As the secret key cannot be read off, this allows you to see if the value has been

written or even if it matches another key.

To check if data has been written:

Step 1: Perform a challenge/response before writing, make a note of the response value.

Step 2: Click the bottom write button to write to the secret key page.

Step 3: Perform another challenge/response and compare the response values. You should find the

two values to be different.

If the two values match, then can either be because the write failed (locked page etc) or the new

data was the same as the data already on the key.

To compare the secret keys of two keys:

Step 1: Insert key 1 and perform a challenge/response against it. Note down the response value.

Step 2: Insert key 2 and perform a challenge/response against that one. Again note down the

response value.

Step 3: Compare the two response values. If they differ then the secret keys too are different.

Please note, that it is technically possible (although highly unlikely) for two different secret keys to

return with the response value for the same challenge. Repeating the challenge/response process

with a different value of challenge should be done when the user wants to make 100% the keys are

the same/different.

ID48 Megamos

This is the tool for custom reading and writing to an ID48 transponder. Clicking read will load in the


Clicking write on the various pages will allow you to write the data on a per page basis.

9


Fixed Code Transponder Tool

This is the tool for custom reading and writing to a fixed code transponder. Clicking read will load in

the data from the transponder inserted into Touchclone. The ID type and data to be written can then

be entered. Clicking write will then load this onto the transponder.

10


PCF7935 Transponder Tool

This is the tool for custom reading and writing to an PCF7935 based transponder. This covers the

ID40-ID45 range of transponders.

Clicking read will load in the data from the transponder inserted into Touchclone.

Clicking write on the various blocks will allow you to write the data on a per block basis.

11


Clicking Extended will bring up the extended transponder information screen:

This page allows you to configure various transponder parameters that affect how it works. Please

note that will only update the previous page values, it won’t automatically write it to the

transponder.

Write Protect: This allows you to select which blocks cannot be written to.

Read From/To: This allows you to select which blocks the transponder will transmit from and to.

Selecting Read Block 1 will make the transponder transmit block 1 before any others.

Shadow Memory Select/Lock: This will select and lock the shadow memory for block 2 respectively.
