Hello,

I lost one of the keys. I ordered similar key. I want to erase all keys from the system and add one of the two keys that's left and a new one.
Can I do it on my own somehow, or should I only go to the dealer to do it?

I found this article: Program Mazda 3 2015 All Smart Keys Lost via OBDSTAR Key Master | Car Key Programmer
but it requires a $500 programmer, which is way too much.

Is it possible to do it using other programmers?

My locksmith buddy told me he couldn't find any programmers that worked for him. He's given up on that business because he thinks the car companies will just change the programmers as soon as a cheap one becomes available. It looks like it's always gonna be a dealer job.

Software is getting to be a real issue for independent car repair shops. NOne of them can get licenses for the software at any reasonable price, so they are mostly going out of business, or turning to working on old cars. Key programming s a similar issue.
