I bought a car with only one key....what if I cut the key open and
glue the chip to the ignition switch and get a couple of keys
cut.....thus avoiding dealer costs in getting new keys?

Should work fine but with some downsides.

Mine is smart enough to work out when the
key is out of the car and turns the headlights
and side lights off when you get out of the car
without turning them off manually.

And you likely will lose the remote lock and
unlock without using the physical key too.

Some cars arent that expensive to get another key
off ebay or aliexpress etc.

got a separate 315 Mc/s fob...
