You need to replace everything that is broken. I have no idea what that includes, but replacing the lock cylinder can be a do-it-yourself project. It slides into the electrical switch which is also not very hard to replace. Your best bet is to get a copy of the manufacturer's service manual. It will give step by step instructions with line drawings. The procedure is the same for Caravans / Voyagers, and full-size "B" vans, so you can use a service manual for one of those too.
Once you see how to remove those parts, if you get replacements from a salvage yard, the people at the dealer's parts department can change the tumblers in the lock cylinder in a few minutes so it will work with your original keys.
If you get a used switch, inspect it's terminals and the plug for any sign of melting plastic or blackened terminals. Any overheating will cause that to happen on your car too. Do not use parts that were overheated.
