One of the keys of this Korg SV-1 was getting stuck so we need to remove that key and a few of the surrounding keys.

This photo shows the Korg "RH-3" keybed removed from the SV-1.

RH-3 keybeds are also used in the Korg Kronos and the Korg M50-88.

To remove a white key from the RH-3 keybed, you push forward on the rear of the key while depressing a hidden "key stopper" (see photo).

A thin tool or a sturdy business card can be used to depress a stopper.

Every white key has a stopper to the left of it.  The 'E', 'F', 'B' and 'C' keys have a ridge marking its exact location (see photo).

This photo shows what the key stoppers look like.

This video demonstrates removing a white key from the RH-3 keybed.

Replacement keys for the Korg SV-1 and Kronos can be purchased on our REPLACEMENT KEYS PAGE.

This video demonstrates removing a black key from the RH-3 keybed.

Black keys don't have a stopper—you just push forward on the rear of the key and lift.

Before removing a black key, its surrounding white keys must be removed.

This video demonstrates installing a white key on the RH-3 keybed.

The black keys are installed in the same way.

A black key must be installed before its adjacent white keys.

The RH-3 key springs are leaf springs and their orientation is important.

The forked end of the key spring straddles the key hammer (see right).

The flat end of the key spring butts up against the rear of the key (see below):

As you guide the leaf spring into the rear of the key, bend the middle of the spring upward (see right).

Each key has a window where you can see if the spring is properly seated.
