Vehicle key

Hello, yesterday I bought a Ford Escort 1.6CL (MK4?) Built 1986 with 86800km. A real retired vehicle. The technology is ok so far, a few optical defects like rust on the rear wheels(there are reperature sheets?) the left front fender is closed and a stone blow in the fron disc. Wes because I write. Are the vehicle keys. Especially since I have “only” two (read that the vehicles were only delivered with 2) with the replacement/workshop slip How do I look with extra keys? Where can I have them done? Only with Ford? I don’t have a key number. Or do I have to buy a complete lock set again? Are there typical flaws in the model series? It’s a 1.6l 16V engine installed with 90 hp. Engine goes well, oil changes are made fresh, tooth rubbing and spark plugs changed even before 2000km. Otherwise, the technology looks quite fresh, whereby I still have to I came to this Ford practically like the Jungfrau, because my Audi gave up the spirit. Ford had only the Galaxy up to now and was actually satisfied with it. I got all the replacement documents to it. Was also regularly waiting at Ford. TÜV/AU are new. KM are original despite only 5 digit speedometers. Is there a conversion rate to Euro 2? I mean the tax is not all too high, but if you can save. I know there are many Questions, but I’m looking for myself dead because I don’t even really know which Ford Escort that is. Love greetings and a Merry Christmas Nijura
