The confusing part is the module now showing SAFE did start the car before putting it in the new housing.
The other module started the car but doesn't unlock it and this is still the case.
So we have the original module that will now unlock but not start the car when it previously did both. The second newer module starts the car and does not unlock it which has always been the case.
All that has been done is to swap the working module into the newer housing as this doesn't have worn buttons and put the new module into the older housing to use as a spare although the remote unlock does not function.
Cloning either would still present an issue would it not? Neither performs both functions.
