The trouble (as I discovered recently) that even with cars of that age, the "manual" keys will still have a transponder chip in it that the new one will need to match, or else the immobilizer will not let you start the car.
There are a few online key replacement sites, but from my searches, they didn't prove to be an awful lot cheaper.
I spent £135 getting a fault diagnosed when mine refused to start periodically. It was the bastard key. Rocked up with the manual spare key and it fired up no bother.
I had this situation with an old polo.. I took the chip out of the existing key and glued it next to the ignition.. this obviously hugely less secure but means spare keys are cheap.
