Before you buy — quick checklist

  • Confirm your topside control unit is an MTS2KU or MTSUV — do not assume based on button count alone
  • Count your existing buttons — this overlay is for 6-button configurations only
  • Check that your existing keypad housing is undamaged — the overlay fits over the existing assembly, it does not replace the housing or PCB
  • Inspect your current overlay's adhesive bond — if the housing itself is cracked or warped, a new overlay alone will not resolve the issue
  • Verify the SKU 650-0520 is listed on your existing overlay or Marquis documentation before ordering

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
