Hi guys

I’m struggling I have SRT6 07 Plate, only 40,000 miles immaculate car. All of a sudden for some reason both key fobs have stopped working I can gain access through drivers door and use internal switch to open passenger door and boot.

I have tried change battery’s
I have also tried following a multiple of tutorials how to re scenic the key fob with no avail, I have been in touch with a multiple of garages who very rudely laugh at me and advise they done deal with crossfires or SRT6.

any support or advise would be much appreciate

Thanks guys
