The mechanical key is not expensive, but most car keys also need to have the electronic code copied as well, and this is where the minimum price is jacked up to around Fr 80,-- by a Mr Minit for a Renault Twingo key!
Maybe, the high price, here, for key copying, is like paying a guarantee that they don't make an additional copy for themselves ........ for later.
15chf for both and no questions about my ownership certificate!
Other surprise, another time, was the low cost of garage loan car, only charged for part day instead of whole day for the 2nd day.
Paid normal rates for mechanical work, but nice to get the extras at a bargain, so did not feel ripped off in any way, the opposite & work well done.
There's a Lidl or Aldi right by the tram stop in a little center. Just inside there's a tabac, cafe and the key place. Usual setup that sells batteries and watch straps and fixes shoes, I don't know the name.
There was a price list up on the wall but the old boy just seemed to make up the prices, a few people popped in while i was there.
