I lost one of my two 2020 MX-5 key fobs, and want to get a replacement one. The dealer wants $175 plus another $150 to program it! That seems ridiculously expensive. Does anyone know of a reasonable alternative to this? Thanks!

 

Try an auto locksmith.

 

You should check online like eBay; I have located a blank key fob for my Infiniti and you maybe able to save a little on parts. The programing is tough, you have to pay the deal cost.
