When I tried to order a key for a Peugeot Recently I Was told by our dealer a that on that model they have a Master key and sub key, And we needed to know which key we already had as you cannot program a master key into a system that already has the master key. ?? I had never heard this before on peugeots but it sounds possible. ? I think ours might have been a 307 but i its got a comms 2000 unit it might be a simlar system. ??
