destroy the key till the chip comes out
most ofd the chips are glued in but usually wont take much to get the chips out, some aftermarket ones are moulded in which case brake out the sharp implements! one of my aftermarket keys had like a square insert bit which pushed in from the back with the ship on the end, just levered out. tbh haven't got anythign to loose from trying if gonna chuck old key away anyway!
this is factory key with light, key without light is similar. chip is in the half at the bottom of the pic, square rectangular thingy. on these it should lever out with minimal effort:
