2015 Mercedes Benz GL550 KEYLESS GO problem. I will post more once the dealership figures out the solution.
my local dealership only escalated this problem to the level of shop foreman.
here's what he sent me...
"If you do not intend to use a SmartKey for an extended period of time, you can deactivate the KEYLESS-GO function of the SmartKey. the SmartKey will then use very little power, thereby conserving the battery power. For the purposes of activation/deactivation, the vehicle must not be nearby.
/\ To deactivate: press the lock button on the SmartKey twice in rapid succession.
/\ To activate: press any button on the SmartKey."
GENIUS! An SUV that costs over $100K has a useless feature to prevent a keyfob battery (CR2025) that costs $1.75 from being used up. You have got to be kidding me! That's wicked smart!!! How about having $1800 tires that last longer than 20K miles? That would make sense.
