Replacing a quadruple key
Removal
The removal procedure for quadruple keys is the same as for single or double keys.
1. Pull off the key cap with the removal tool.
2. Pull off the key with the removal tool. Be careful not to bend the springs attached to the
key.
3. Remove the two black rubber rings.
4. Remove the two key guides with the opposite end of the removal tool.
Attaching
Note: Make sure the smaller keys, the rubber rings,
and the key guides are removed from the place
where the quadruple key will be attached.
1. Find the pair of diagonally opposite holes that will
not need scan codes. Insert two key guides in
those holes.
2. Place the two black rubber rings around the key
guides.
