No dash lights after intake manifold
If so, try it.
I just dropped my key on hardwood floor yesterday evening, it really creeped me out. The things are so delicate.
Even at $300+ dollars, a known good spare key is often cheaper than ignition security diagnostics at an MB dealer.
Dealer might actually suggest getting one as first diagnostic step.
That said, I only have one working key myself (grins sheepishly).
