Key problem M35

[NisFin321]

My 2007 infiniti M35 doesn't start without the key in fob it said low battery so I changed it into a Dl 2025 but also have a cr2025 but it still doesn't start it also started unlocking all my doors with just one click on the door how do I fix this?

I just bought an M35 last week so I'm still not too knowledgable about them. However, I know that you can change the unlocking issue by going into the settings screen while the vehicle is in park or stopped. If i remember correctly, there's an option titled "convenience" and within that section you'll find an option for the unlocking mode, it can either unlock every door or just the one door. As for the starting issue, I have absolutely no idea. Good luck!
