Keys sticking, half the letters not registering, or a membrane that's finally given out after years of daily use — you know the frustration of trying to get work done on a board that fights you. This is the LEADER keyboard assembly for the Companion SC530 and SC530PRO. One thing to flag before you order: this is the keyboard only, and it requires plastic welding to seat it properly into the chassis. If your tech handles that, it's a straightforward swap. If not, call us and we'll point you in the right direction. We've got 18 on the shelf right now, so you're not waiting on a backorder. Add to cart when you're ready
