V70: Electrical - Remote start with arduino+SMS

Hi,
I'm just wondering maybe any of you can share some knowledge about possibilities to start the car remotely.
Car - Volvo V70 2008m 2.4 diesel, automatic gearbox, with start/stop button.
My friend and I wondered what can we do with arduino board and the Idea came along to build a board to start a car remotely via SMS. So now everything works fine, we simulate two brake signals (one NO and one NC relay) and one relay for start button but the problem is that if we want to start the car the key should be placed in the socket. So if the key is placed in the socket we cannot lock the car with another key so basically then the car should be locked manually and unlocked manually which is "not great not terrible".
So just wondering can someone share some knowledge is it possible to bypass immobilizer and start the car even though the key is not in the place? Or simulate somehow immobilizer signals with arduino?
Thank you in advance.

Would love to do this.
I bought a cheap kit from China that uses Bluetooth to do it.
Mine has keyless entry and start and I decided that I could do a lot of damage to the electronics if I messed up the wiring of it so I decided it was not worth the risk. Its still in the box in the garage 😂
Hope you get it sorted, I'd love to see it work.
