Puzzled as to why you want a new transponder It works and replacing the transponder isn't straightforward, requires specialised equipment which only a handful of the traders have.

The remote PCB is another matter, as long as you have access to either a T4 or somebody who knows what they're doing with TOAF you can enter replacement PCB serial number.

You can buy a secondhand key and transfer the PCB to your key and program it using Marinabrian's instructions here.

Alternatively, new microswitches are available -

however, you'll need fine soldering skills to replace them.
