I've got a friend who has found an E3000 he wants to purchase. However, the owner has lost the power on key to it. My friend has several E450s and has the key to them. Will this work in the 3000? If not, then how hard is it going to be for him to obtain a key? Jeff -- "...and the burnt fool's bandaged finger goes wobbling back to the fire." -Joe Zeff in the SDM.
