Hello from France!

I'm writing on behalf of a friend out here who has a problem with his
automatic gate. The gate is remote controlled, and works perfectly well
normally, but has one (major) problem - it often opens all on its own.
Mostly during the day, not often at night, less at weekends - leading us
to think that perhaps it is when a certain car drives past, or possibly
someone on a mobile phone - or could it be vibrations? The company that
installed it has gone out of business, and we can't find a brand name
anywhere, except the circuit board which is marked 'IKOR'. Does anyone
have any experience of this kind of problem, is it possible to change the
frequency perhaps? The system is run by a battery which is kept recharged
automatically. Any ideas?

Both the receiver board and the zapper should have a row of DIP switches
that set the code, probably behind the battery in the zapper. On mine, it
was set to 10101010 and, so it would appear, was one nearby. Resetting the
code to something rather more random cured the problem.
