In fobgina it works perfectly.
From what I understood from this link : Intelligent Key and BCM Troubleshooting

There are many antennas (outside key antenna and inside key antenna). It's said : 'Generally when the request switch is pressed, the BCM energizes only the respective door antenna.'

So I tested today, buttons (unlock/lock) on the keyfob didn't work, I pressed 5 seconds on the switch button of the driver side door and pressed again just once, it's working fine.
I can unlock/lock with buttons on keyfob (even when I am 10m (33ft) away) and I can start the car normally (keyfob in pocket).When the engine is started and when I'm get out of my car, he detects that I am going out with an alarm. I don't think that it was an antenna because after doing this (press 5 second on switch button), keyfob works perfectly but it only works for a few minutes or a few hours when the car is closed.... Example : When I drive, I have no problem with the keyfob. My car continues to detect the keyfob in my pocket . But when I take my car after work or restaurant, keyfob doesn't work.
For it to work again, I must press 5 seconds on the switch button of the driver side door and press it again just once ....every time the keyfob no longer works.

In any case, something triggers the proper functioning of the keyfob when I press the switch button on the door.
