Teenage Engineering OP-1 Battery Replacement

Open the back panel by using a Jimmy on the side of the panel. Be careful not to damage the OP-1 coating.

Lift the back panel and remove it. The Connector Board is revealed.

Disconnect the flex connector by lifting it up with a spudger.

The four longer keys from the fingerboard are to be handled from the left side to get them off.

The eight smaller keys need to be levered from the bottom up.

The scissor mechanism of the eight small keys are obstructing the underlying screws.

By using again an opening tool or opening pick these can be snapped off easily.

Loosen those 12 screws with a Phillips #00 screwdriver.

Then just pull off the four rotary knobs and the volume knob.

Now it is possible to slightly lift the keyboard and set it back.

Carefully pull out the connector cable from the connector board and bend it out of the way.

Disconnect the battery with a spudger. The connector needs to be lifted up and not being pulled to the side.

Now you can pry out the battery which is glued in with double sided adhesive tape.
