My 2015 Mercedes Benz SLS Class is basically useless until I get this code. Fingers crossed.

I’ve got a 2012 2015 Mercedes Benz SLS Class, would this method still work?

Finally, something that might help with my 2015 Mercedes Benz SLS Class's key code issue!

Trying this on my 2015 Mercedes Benz SLS Class later. Will report back.

Hope I’m not too late to try this on my 2015 Mercedes Benz SLS Class.

Has anyone gotten this method to work on a 2015 Mercedes Benz SLS Class before?
