X308; Key transponder module

I am in the process of breaking an X308 and want to retain the keys and locks as a set. Now, the keys are coded to that specific car via a transponder so, obviously, I need to bring the Key Transponder module into the mix.

My questions are: Whereabouts in the vehicle do I find the Key Transponder module, and is the anything else I need to bring along in order to be able to use the keys, locks, and transponder in a different X308?

Thank you!

Kind regards,
Bard Thomas

they are also coded to the ECU . so if you want to use in another vehicle you need ignition key barrel , ECU and key transponder module. the module can be accessed by removing the speedometer cluster it is underneath and towards steering column…
