Amanda Riphnykhazova udtrykte præcist:
Any one got any ideas as to how to identify the frequency for the lock/unlock
function? And if I do, how easy is it to find another transmitter at that
frequency which controls a simple on/off switch?

Model unidentifiable though I am informed that UK models of this make only
used two frequencies, 315 and 433 Mhz

US models however used different frequencies. Curiously enough people say
that the 315 and 433 Mhz fobs can be bought but the mysterious american ones
can't. And that since the car was built in the mid 1990s, technology has
moved so far forward (on a simple on/off switch??) that the technology is
obsolete and new fobs are unavailable; and that I have to buy another
receiver unit and matching fob at a cost of $600!

Does this sound plausible?

Sounds plausible.

I lost one key to the (dealer-mounted?) immobilizer, and went to the
company in Magdeburg, who sold millions around 15 years ago, when
immobilizers got mandatory in Germany.
They had a little plastic bag with the remaining couple of hundred
rfid-chips. When they were gone, there were no more...
