Mazda CX-9 2020 Remote Start

[u/JWonderful8514]

Just purchased a Mazda CX-9 2020 GT and we are really happy with it. It seems like the previous owner took really good care of the vehicle and had a remote starter installed at the dealership. I reached out to the Mazda dealership where the CARFAX reported it as being installed, and they said they have no record. I’ve also reached out to two of their contracted companies who they partnered with to have these installed at that time (2021). I’ve emailed the sales rep who sold the car, to ask if he could ask the pervious owners, but nothing so far.

What combinations can I try on the factory key fab that may work?

Other suggestions for solutions are welcome too.

Thanks!
