A:AnswerThese are just remote start systems. If you want one of these as well as one including an alarm with it, you will need to upgrade further up then this. They do sell whole alarm sysytems which include remote starts and has key phobs but its more money.
A:AnswerThe ignition key is different then the key phob. The key phob can be programmed if you have zero key phobs, each are programmed differently. I dont think they will program a second ignition key and cut it for you thats normally a locksmith. But if its a key phob you have this will make 3 that you can have. They program the phobs differently tho.
A:AnswerDan, I'd be guessing. My purchase was installed today on my wife's 2016 Nissan Rogue. Weather here still not too frosty. At installation, I was asked to bring my wife's key and mine also so apparently it will recognize whoever is using his/her key to start. Otherwise if you can reach Antonio or Nate in the Hyannis, MA auto installation department, they are super. Best wishes.
