To recode or read the EWS (to program keys) you have to remove it from the vehicle. You need a special EWS tool to read/program keys and to read/program the EWS.

6 digit code? I don't know what that would be for. The keys (as in the numbers/codes inside the key and EWS) are much longer than that. The circuit board is mostly the remote control section. The actual RF ID bit is usually separate in a corner near where the metal part of the key comes out of the plastic so it's close to the antenna inside the ignition switch. It's a self contained part and looks like a small integrated circuit chip with a corner cut off but with no pins. That's what the car talks to. Like this
