Hi, I have a Smart Forttwo 450 700cc, 2003 year.
When I press the key remote, door don't open or close, but it blinking light. No sound for the lock.
When I put the key in the ignition. Car doesn't start, rear panel has a key sign blinking.
I have two keys and I was testing both.
I open the SAM device, all was ok, no burnt no black marks on pin. A little humidity on some pins, but is a minor issue. I open and clear all pins, no water damage on board. Even I clean the cables and connector with WD40. All fuses and connector clean and checked.
Nothing has changed.
How can do?
