Changing boots

[FamiliarOfZero]

Hi i have a 2001 VX Berlina. The current boot has no spoiler, and i have now come into possession of a new boot with a spoiler(same colour). Just wondering how hard it would be to flip them over, i.e the electronic release mechanism, does that need to be switched because of the key frequency of the release? or is the frequency receiver kept else where. And just how hard it is to re-wire the boot. I.e unplugging the wires and pulling them out to put into the new one.

Thanks heaps
