Team, remote buttons were completely worn out of my MJD 2010 Linea. So ordered the Shell on amazon and transferred the motherboard. However afterwards, my car does not start. Remote buttons are working fine though. When contacted the service center, I have been told there should be a tiny chip inside the key, which I did not find (I was careful though that I should not misplace anything contained in my old key). Service center tells me I shall need a new key to be made for 4300/-. The challenge I am facing that I have to carry both spare key and the Remote Cell and no spare key at home in case of any eventuality. Suggestions most welcome to resolve this.
