KCET option entry is typically locked before the option-entry deadline ends , and the lock action is done manually on the portal once you finish arranging your choices. For KCET 2026, one source says the option-entry window opened on June 10, 2026, and another says candidates should lock the choices when the option is available and before the deadline closes.

Is there a button?

Yes — the portal usually has a Save/Continue step and a separate Lock option/button for final submission. After locking, the choices generally cannot be changed unless the authority reopens editing.

What to do

  • Fill your colleges and branches in priority order.
  • Save the list first.
  • Use the Lock button only after double-checking everything.
  • Keep a copy of the final option-entry slip for reference.

Important note

If you miss the lock step, the system may not treat your choices as final, even if you saved them earlier.
