How can I copy a locked SD card?

I own a British Columbia Backroads Atlas Micro SD Card for Garmin. It is locked to the serial number of the card and apparently cannot be copied. Does anyone know how to make a copy?

I would like to copy the files onto a larger micro sd which already contains Ibycus Topo and a couple of custom Garmin Maps. I am getting tired of having to change back and forth between cards while using my truck mount GPS.

I would also like to make a second copy so that I can leave a copy in my field GPS instead of changing back and forth everytime I leave the truck.

I have limited computer skill so I really apperiate simple and clear instructions.

Thanks in advance for your help.

put your new sd-card to garmin and look cardID
then make new unlock key with Jetmouse keygen
what is your device?

or just use your deviceID to make key

this would work for a garman 60 csx and bc backroad map sd card
