!!! Be very careful when disassembling the original card. I broke one key during this process !!!

Just disassemble the card - you must broke the cover to get the inner electronics.
Open back, remove battery and then try to open the rest. This is risky part.

Then print these parts, use glue for inserts - glue it into one part (A+B). This is not necessary, but it helps to hold the battery in place.

Assemble and try. It works well for me.
Now I am able to simply open or lock my car in pocket without getting the card out of the pocket.

X = lock
O = open

Glue the signs on place. This is tricky part. Use tweezers.

Enjoy.
