I only have one Meta fob and though I should get another one for just incase.
I have the 16 digit code so no worries.
I've found this company on eBay but am just a little wary of sending them my 16 digit code and obviously they'll have my address to post it to. eBay link
Maybe I'm being really paranoid but what's to stop these people keeping your code and address on file and potentially selling fobs and information of the cars whereabouts on to organised car criminals?
Would you go straight to Meta for peace of mind or risk it for the 40% saving.
