https://cash.me/$KenWhu The modification shown in this video was done on a w220 S-class mercedes. In this video I show you how to repair your Mercedes key fob with a sheet of paper (card stock [less folds], bond stock, or regular printer paper will work) Mercedes dealership quoted me $500 for a new copied key and also said that more than likely I would have to also change the ESV/ELV (key tumbler/ignition key lock) for an additional $800. Thats a total of $1,300. Instead, using this method it may only cost you $0.01. Yes that’s right only 1 cent. And for those wondering, the check engine light seen at the end of the video was pertaining to a separate “bank 1, sense 1” issue. :) 😁 🤫 I hope this helps you all with this issue.
