Are remotes even programable or do you program the car to read the remote?
I guess it's similar to aftermarket tpms sensors, you can either buy pre "programmed/setup" for that model them then register them to the car via obdII port or buy cloneable ones and clone the tpms sensors that you already have using a completely different tool(in most cases).
This might be useful for someone. You can look up different part numbers for different models and years. https://www.americankeysupply.com/se...e-product/6815
