Thanks for the info... I will put a 5.1v zener in the path of the input signal...

Sorry for the late answer, I've been very busy the last few days. Using high voltage programming mode, all flash PIC devices can be reprogrammed, regardless of MCLR, LVP or code protection settings. But, when using MCLR as an input, you should consider an external protection diode. A circuit nearly drove me crazy, for almost each time I pressed a certain button, the PIC would reset. The reason turned out to be a glitch on the MCLR pin above Vdd. It briefly turned the PIC to programming mode, and therefore caused a reset via the not-configured-as-reset pin.
