There's nothing to alter there the IC is the blob under that little board no way to do anything with it even if you could get to it it's silicon right on the PCB. You could detach the push button though and run a wire to a better location as long as it wasn't too far a way. If you have any old telephone cable floating around that should be sufficient for a remote run of a dozen feet or so. Those types of switch are momentary push button, all you'd need is a soldering iron and a few minutes. Just hot glue where the wire exits the casing very well to seal it, same with the remote switch.
