    I agree with everything Phyllis Barr said on 10/15/2020. The key override system works great, but the spindle that was sent was not the right size. Two spindles later that also didn’t fit, I had to make my own–which I guess I should have done in the first place. You really need to send out the correct spindle when a key override system is purchased.

  2. Compatibility of KOS2835 with 2210

    Phyllis Barr (verified owner)

    Both are great products but integration is poor. The two spindles included with the 2210 were not long enough for the combination with the KOS2835. The longer spindle provided by all key was just the correct length but was too wide to fit through the deadbolt channel. After trimming to width of two shorter spindles, lock works fine. Proper spindle should have been included with KOS2835.
