They are not talking about the button fob types. They are
referring to the proximity fobs, no buttons. The thief uses
what amounts to a range extender to make it seem like the
fob is close to the car.

 All,

 It seems to me the only way the key fob is going to be able
to be
copied is if someone presses one of the
 buttons to transmit the signal.  If it is just sitting on a
table or
hanging on a wall hook, how would
 someone outside the home (or bldg.) cause the key fob to
transmit?  As
far as I know, key fobs are not
 receivers.  They're only transmitters.  So unless I'm
missing
something, I think the whole idea of
 copying the code from a key fob is a load of bull.=20
 Now, if someone were near their car and they were to press
a button, I
could see where someone could=20
 capture the code, and possible use it for malicious
purposes.  But
copying it outside the home or bldg.
 while just sitting there, I don't think so.
 If someone know that this happens, please explain it to me
so I too can
understand.

 Regards,

 Jim
