Large liquid argon TPC detector programs such as LBNE and LAGUNA-LBNO will beable to make measurements of the proton lifetime which will outperformCherenkov detectors in the proton decay channel $p \rightarrow K^{+}\nu$. Atthe large depths which are proposed for such experiments, a non-negligiblesource of isolated charged kaons may be produced in the showers of cosmogenicmuons. We present an estimate of the cosmogenic muon background to proton decayin the $p \rightarrow K^{+}\nu$ channel. The simulation of muon transport to adepth of 4 km w.e, is performed in the MUSIC framework and the propagation ofmuons and secondary particles through to a cylindrical 20 kt LAr target isperformed using Geant4. An exposure time of 100 years is considered, with arate of $< 0.0012$ events/kt/year at 90$\%$ CL predicted from our simulations.
