what do i need to flash 83850c

have you tried to dump its key using the v1 method, you might get lucky, I did, mine was made august 09 and it dumped its key without cuts / soldering. if you havent tried it give it a go you might not need to buy anything other than a ck3, if you dont already have one.

Ditto mine is an aug 09 and didn't need soldering. Your on the cusp of when the newer ones came out. See if you can do it without the solder first. If it don't work then you'll know you need to solder.
