Could anybody throw some light about what might be happening?
Thank you.

when you manually lock the door with the key blade, the car is NOT armed. It will lock the car but the system is not armed. Only locking the car with the remote will arm the system. It seems one of your door is not closed shut, check if any debris or anything is in the way. Also check the tail gate to see if it is shut good, i.e. without any play.
