  The weak kaon production off the nucleon induced by neutrinos and
antineutrinos is studied at low and intermediate energies of interest for some
ongoing and future neutrino oscillation experiments. We develop a microscopical
model based on the SU(3) chiral Lagrangians. The studied mechanisms are the
main source of kaon production for neutrino energies up to 2 GeV for the
various channels and the cross sections are large enough to be amenable to be
measured by experiments such as Minerva, T2K and NO$\nu$A.
