I actually have 2 keyboards to sell as parts here - these keys may fit models listed in the title, but both keyboards were originally used with a 5733.

There are differences in how the keys clip - see pic 1 (landscape) vs pic 2 (portrait) for different fixings for the same key. I will need you to confirm which you need in order to select parts & post.

Happy to combine postage if you need multiple keys.

Will supply with the hinge bit and the rubber spring.

At the time of listing, all keys are in stock, will update listing if they sell.
