    Awesome job bro!! keep up the good work, I will make sure I will do your project. I have some question if I may ask. How to control all the four relays separately through a phone call or/and SMS? How can I set relay one to go one for one seconds only, and relay four to stay on for 3 seconds. Can I have it code protected so in case someone calls the numbers none of the relays would trigger? Thank you once again. Yazen

    Thank you very much for the instructions, I am going to do it for sure. I have one question if I may ask, I have three buttons on my FOB, remote start, lock and unlock. Can I wire the lock and unlock buttons to relay 2 and relay 3, so I can lock and unlock the doors? Thank you once again

Can I wire the lock and unlock buttons to relay 2 and relay 3, so I can lock and unlock the doors? Do I need to wire relay 4 to the remote start button as well as the first relay if I wanted to use SMS command or call? will that work? Thank you once again
