About to make a purchase of a second hand Xsara Picasso. I noticed that
there was a 'plip' key and a non 'plip' key. Will the 'non plip' key operate
the car when the plip key is not nearby? I lost the key to a previous car
that had such a system and the 'third' spare 'non plip' key did not allow
the engine to start!!!

Is it true that Citroen only provide one 'plip' key?
