I want to buy one, and it’s getting kind of frustrating to do so. If any of you guys has a replacement keyboard for the OP-1 to sell, please contact me
I take it you tried here? https://eustore.ifixit.com/en/Parts/Teenage-Engineering-Parts/OP-1-Keyboard.html
Although it is listed as out of stock it says it can be ordered.
I did, but is not purchasable

Not the full keyboard but who knows… Hope it helps.
cant just get it repaired by TE?
I still have a broken keyboard (one key not working), but I think you are looking for a working one … What is broken on yours? I had a key that was “dead”. Someone suggested to check the ribbon cable connections, but i did not helped on mine. Have you tried it?

I have a key that’s stuck with sound. I removed the key, removed they keyboard, tried everything. The problem is really similar to yours, but instead of being dead, it’s just stucked sounding. (Used to be dead though). Has to be a problem with the circuit, TE says that keyboard needs to be replaced, but they won’t sell me one. They want me to send my op-1 to sweden, from LIMA, PERU. That’s really expensive. And just hope they will fix it when they feel like it. I ask for address, but they take days to respond between line and line in our conversation. It’s 100% frustrating, worst support i have ever experienced.
