Hi i have a peugeot 207 and only have one flip key?

You may as well buy it from the dealer.I bought one off eBay for 35 quid and went to a guy to get it reprogrammed and he wanted to charge me at least 100 pounds to do it.This was for a vw,but i would imagine it will be around the same price for a Pug.At least when you buy from the dealer you will have a guarantee.Good luck.
