@Jumper - the SOP14 SMD chip is surrounded by other components and there is minimal headroom so a breakout board wouldn't work even if I designed one with the correct pin mapping. Plus, the (elderly) people who will have to do the work are total novices who could probably handle direct replacement of an SOP14 size chip (with a hot air rework station) but not much else as far as SMD.

But, it turns out the Sonix chip in the keyfob is powered by 12V directly to the chip so I will have to find another way to do this.
