Engine Vibration

I have what appears to be an engine vibration between 3-5k rpms. Not much just my keys start to buzz slightly, do you think there is a problem?:confused:

I get this too at about 3.5k rpm and about 70mph on the highway. My solution was to have the ignition key on its own ring. No other keys to vibrate together now. ;)

Your engine is probably just finding the resonance frequency of the chassis. I wouldn't worry about it. If your keys are rattling, even changing the order of the keys can change the frequency at which they will resonate.
