Is there a way to temporarily disable the remote door unlocker on my 2002
focus wagon? I found the black module behind the glove box, but I don't know
which wire to cut.
Reason for doing this is to prevent someone with evil intent from using their
electronics knowhow to break into my car. This happened to a friend, and the
police told her the theives are using a scanner device to try all the
available codes until the doors open.

Why bother? 99.99 percent of thieves wanting to get into your car will
usually smash a window rather than walking around with a scanner. Those
wanting to break into cars are not too worried about leaving the car in
a pristine condition afterwards.

I don't think that the criminals try all the available codes - it should
take too long. More probable is that they wait in car parks recording
the code when the door is locked and then when the owner walks away they
replay the code to unlock the door. The simple way to overcome this is
to lock the door with the key in the lock rather than pressing one of
the remote buttons.

That sounds like a good suggestion. I wonder, though if pressing the "Lock"
button inside the car generates an RF signal just as the keyfob does?

In this particular case, smashing windows was unlikely, as it was a busy
parking lot. These guys used a different tactic. They would leave everything
in place, taking maybe one credit card, hoping the owner would not notice.
That way they can use it until the owner notices it missing. If you come back
to the car and it is obvious it was broken into and your wallet is missing,
you will call the credit card companies as soon as you can.

Another method used is to use a crowbar and leaver the to of the door
until they can reach the switch/button to unlock the door. No sound of
breaking glass and they don't care that the door is bent and so is the roof.

But the easiest way not to get your credit card or wallet nicked from
the car is not to leave it there.
