Marshall - I'll take a stab at this one too.. If it is the P22 model, the key cover is two pieces connected by a long hinge. To find the lever, take the back section of the key cover and tilt it towards the player. There is a horizontal pin that is the contact point to the piano body. The key cover has a "Y" type (inverted)piece of metal that rests on this pin. To keep the Y shaped yoke connected, there is a slide lever, similar to the type in a Wurlitzer school type upright for the music board. Once you find that lever the key cover just lifts up and off. Hope this helps. Ron Koval chicagoland
