Before you buy — quick checklist

Confirm your spa uses a Sentry 800 control system — check your existing keypad label or control box
Verify the existing keypad is rectangle-shaped, not oval or round — shape and connector type must match
Inspect the cable connector on your current keypad before ordering to ensure pin configuration matches
Check the cutout dimensions on your spa shell — the 6600-803 must seat flush in the existing opening
If your spa is outside warranty, photograph your current wiring before disconnecting anything

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