Sigh! I swapped the contents of my key fob over to a new case because the old one was cracked-only it will no longer start the engine as the imobiliser keeps kicking in-anti-theft etc. I need an extra key so I was wondering if one of those mobile key cutting units could do the job cheaper than a main dealer as they claim to be able to cut car keys and code them. Anybody know if this will work. the key is for a peugeot 207. thanks
