Is it really made in such a way that one can get in the car and drive away without having to have a key fob?

I set the alarm to an armed position, then waited 15 seconds. Then opened the door with the key, and started the car all without having to disarm it????


Is that really how it's designed? So to disarm the alarm I don't have to to have the key fob, and just have the right physical key???? Or does it somehow sense the chip in the key?

Shoot, does it mean the thief with the correctly cut key can drive it away like it doesn't even have any immobilizer???

 

The keys have chips embedded in them and they are coded to correspond with your alarm, so using the key in the door cylinder to unlock the car will unarm the alarm as well as the immobilizer and allow you to start the car. On the other hand, if you are inside the car while the alarm armed and try to start the car, the immobilizer will not allow the engine to start and the alarm will sound.

 

So you are saying that the electronic chip disarms the immobilizer when you turn the key in the ignition lock?

So how would it do that?

Does it send the signal to the receiver to disarm it or does the lock itself disarm the system when it's turned? If it sends the signal to disarm, what causes the signal to be sent?

If it's not a signal and is based on some sort of magnetic properties and it intaracts with the receiver while in close proximity, then again, at what point will it be able to disable the alarm? Hope this questions make sense.

 

Yes, a signal is sent to arm/unarm the alarm via the driver door it is turned clockwise or counterclockwise. How does it beats me but I am sure that the key is transmitting the signal because whenever the key is turned to the lock position, the doors lock and the alarm is armed. In contrast, whenever you turn to the unlock position, the driver door will unlock and if you turn the key to the unlock position once more, the remaining doors and hatch will unlock. Much like using the key fob.
