SD Card Toolbox. Lock unlock with password. CID reading and more…

Reading SD card CID number was cumbersome and inconvenient process that took more time than it should, especially for Windows users. Not to mention locking and unlocking SD card with a password, it was impossible on the Windows operating system at all.

We believe that this process should not be so tricky and inconvenient so we have created a small handy device for tasks with a SD card security features and called it SD Toolbox. As this has been a great success among the users, we understand the importance of the device and are constantly updating it and offering new features.

So let’s dive into the opportunities it offers…

Main features

  • SD, SDHC & SDXC cards supported
  • Read SD card type and size
  • Read & Decode SD card CID number
  • Decode CID number without SD card
  • Read & Decode CSD number
  • Lock & Unlock card with password*
  • Set/Remove temporary write protection
  • FAT32/exFAT partition hiding
  • Erase card and remove all protections

* unfortunately it doesn’t extract unknown passwords from SD cards. Password must be known in order to unlock SD card


Because this device has gained success mainly among car electronics enthusiasts and professionals we have added some optional features especially for them

  1. hello,
    I installed the toolkit, but it seem to need a special SD Card reader ? It reports device not connected…

      • Can i knowyour tool can unlockit the bmw headunit sd card with password?because i know is sd card problem but it lock we cannot do anything.

        • Password must be known to unlock it. If you don’t have a password, you will not be able to unlock it.

  2. Hi.

    The SD card toolbox reader arrived today, I have downloaded and installed the software from your website. However when connected to my PC (running Windows 10 Pro, 16gb ram) and SD card inserted into reader, reader flashes a Blue light once but software says SD card removed then after approx 10 seconds software program says it is not responding

    Can you help ?

    Regards
    Dave

    • Hi Dave,
      Please take a look to the left bottom corner on software window. Does it say ‘Device connected’ ? What message you have there when starting software with reader plugged in?

      SD toolbox works thru virtual com port, the number on bottom left side shows how many ports detected on your PC and tries to connect to reader by sending requests to each port one by one. If there are unresponsive ports such as Bluetooth com ports actually not connected to PC or some dead com port drivers, software doesn’t receive response and might wait forever.
      There are 2 solutions at the moment:
      1. Check your com port in Control Panel and disable unused ports
      2. Start 2nd instance of SD Toolbox software and then close the first one. 2nd instance of software will not be able access problematic com port because its occupied with the 1st instance and should work normally

      This problem is pretty rare, but sometimes it happens and I will fix this issue in new software versions

  3. Issue resolved very quickly with help from Zelemar. I can now use the SD card reader to read codes. Thanks for all your help in resolving the issue so quickly. Great service !!!!!!

  4. Hello

    I bought a SD Card Toolbox a few weeks ago and received it today. Unfortunately it seems the device is able only to read the CID number and doesn’t allow to change it. Is there a future update planned for such functionality ? If not, can you please recommend a tool that can do this ?!
    Thank you

    Best regards,
    Robert P.

    • CID changing is not possible yet. Currently we are working on it and i really hope to offer CID changing in a future updates. But its in the development stage still.

      • Thank you for the quick reply. I hope you can make it happen. That was the only reason for buying the tool, I didn’t think it only reads it, I thought it can also change it … Happy Holidays
        Best regards,
        Robert P.

    • There are 2 types of Write Protection: temporary and permanent. Temporary write protection can be removed using this tool, permanent – not.

  5. Hi,
    I inserted the card into the microsd slot in my pc, ran the software, but only get a greyed out sdcard graphic in the UI, like it’s not connected.
    Computer shows its connected though, any ideas?

    • HI,
      SD card toolbox software works only with its own hardware, not with the PC reader. So you have to use SD toolbox hardware and software together.

  6. Unfortunately it seems the device is able only to read the CID number and doesn’t allow to change it. Is there a future update planned for such functionality
    But other seller has this function to change cig on samsung

    • CID change on Samsung EVO easily can be done on Ubuntu. CID change feature in SD toolbox is planned in the future and probably not only for Samsung 😉

        • I have some planned updates for the same hardware. But the CID programming option probably will require hardware changes.

          • When is the new hardware coming? I want to buy a device. Should I wait?

          • It’s still in the development phase and it’s hard to predict a release date yet. You can buy an existing device now and start using it.

  7. Thanks for the program.
    Could you pelase consider to enable multilanguage interface?
    Thanks.

  8. Windows 10 Defender reports SD Toolbox portable version (v2.5.0) as Trojan:Win32/Wacatac.B!ml

    • SD Toolbox portable version is packed (.dll and .exe packed to a single .exe file), that’s why some antivirus is suspicious about that. I can assure you, the software is clear from viruses and trojans

  9. Mitsubishi – used for Mitsubishi MMCS

    Does it need specific cid + pw ? or just lock any sd / Cid in MMCS mode ?

    • MMCS doesnt need specific CID, any SD card of 16Gb can be used. Password is the same for all MMCS units and not related to CID.
      Contents must be cloned, not copied, as it contains some hidden data with navigation software/firmware.

        • Yes, use MMCS mode and set password. If you want to unlock the original SD from MMCS, press Clear password

    • The software works with the SD toolbox hardware only! it doesn’t work with a regular SD card reader.

      • Hi,
        I changed the browser to Chrome and then I could download the file.
        I had to press the card in the slot with my finger to be able to read the card.
        Is that correct or is it somthing wrong with may box?
        RTegards Tommy J

        • Hi,
          nope, SD card slot must be working without any issues. Maybe something fell inside. Try several times in series to insert and remove SD, and it should work without any pressing on card.

  10. Hello,
    can i use the Toolbox also to make a Backup for VW,AUDI or SEAT navigation SD Card. And ensure that it will work.

    • It cannot be used directly to make a Backup. SD card backup can be made with a number of clonning software. The simple and good working software for backups is HDD Raw Copy tool
      The most of navigation SD cards are protected by encrypting contents or creating license files by SD card CID number. That’s where SD Toolbox can be usefull, it allows to read CID which is necessary for custom CID sd card ordering. Also it can be used for VW rns315 navigation cards locking and unlocking, as well in other tasks described in the article

  11. Few days back i have purchased this device can we change the id card id with this please tell me some thing about it.

    • you will not be able to change card id with it. Card CID is read only with this tool
