    hey guys, i'll be honest i almost messed up both keys at one stage and the chip was covered in molten solder, brought a gas powered soldering iron which i thought would release it quicker but it started to burn the board so i gave that a miss. then went back to conventional soldering iron, basically joined all the pins on one side and the same on the other... then used some dentist tools to pick it off the board. once it was off used some desolering braid to clean it.

    After this i soldered it on to the new key board and tested the key. the first time the boot opned but nothing else...

    then went over the solder joints again and tested then worked fine...

    wont be doing that in a hurry again.

    Great job - I've got two of these new chrome keys sitting on top of the shelf getting dusty.

    Wish I could just transfer mine over.

    make sure its not the brrand brand new type with squarish buttons as these do not have the same chip inside

    Is there a way to do something similar with the old brick/flick keys like my W124 has? It steadfastly refuses to come back to life after the normal resoldering (as explained elsewhere on this forum) so I was wondering if I could transfer any specific part into a new keyfob before trying to get a day's overtime to buy a new key.
