Peugeot 407 high freq. sensor location

[razvancolceriu]

Hy!
Anyone knows where the remote key sensor is located at a Peugeot 407?
The remote keys do not work, i have 3 keys.
I tried to resynchronize by holding the lock button for 10 second, etc... but not work.
I do the BSI reset procedure by disconnecting the battery, wait 5 mins, put the batt back, turning on the sidelights from the driver window, etc... no succes.
The PP2000 says 'communication error' on high freq.
Anyone knows where is located the receptor from the key?
Thank's!

PS: The car start and work properly, but the keys are dead. I need to unlock the car classically.
It's hard, especially when is frozen... -_-
