I really like my joyetech egrip works great but it locked how do I unlock it
So I know this is over a year old, but I just had the same issue and was trying to resolve it. Nobody seems to have the answer. But I figured it out in a fit of frustration so maybe the next time someone Googles the issue, they'll stumble across my answer here.
It's not the firing lock. The device still fires. It's the key lock for the up/down menu keys so you can't adjust the wattage or anything.
The truck is the "center" button that you don't even know is there. So the up/down button is a single button with two ends that you use to cycle through menu options.
To turn the actual key lock off, press and hold IN BETWEEN the two butons, right in the center of the joint up/down button. It turns the lock on and off.
