The keys do have a chip in them. My key fits Tim Sheehan’s ignition and
door, but will not turn in either. The steering wheel does extend and move
down as if I was about to start the Jag though, so that works off a physical
connection rather then software/chip recognition =)
Your alarm system is/was malfunctioning then. Unlocking the door should
have disabled all alarm features and not have sounded on opening the drivers
door. Or have sounded if you unlocked it with key twice to allow the
passenger/trunk to be opened.
Disconnection of the battery will do you no good to steal a Jag. The X300’s
automatically return to the alarm/lock state it was in when you removed the
battery, its a built in failsafe in the system. You either disarm the alarm
or you bypass the alarm system completely. Otherwise you get an immobilized
Jag or a screeching one that won’t go away even if you do get it started.
Anti-towing sensors are also included in the X300’s. The European market
also has to contend with radio codes if the battery is removed long
Thats why keys are so expensive, not only are they just odd shaped but you
need to have it “programmed” for your car. How else does the Jag know a
valet key is inserted into the ignition?
Any locksmith worth their weight has directions on how to unlock a Jag
without a key through the X300’s, I’ve seen the steps myself when doing some
consulting work for one, but bypassing the alarm is another matter entirely!
Argh, its nearly 3am here and I’m supposed to be up for work at 6:20am…
this is going to be a long and tiring day for staying out late to party…

Not sure if this is of any use at all, but on my '95 X300 when the alarm
keyfob was playing up I used to unlock the door with the key, after
physically opening the door the alarm started to sound, but stopped
after I inserted the key into the ignition and started the engine. This
may mean either the key has a chip in it, or more likely it didn’t
immobilise the engine.

Just bought a '95 XJ6. Lovely car, but I live in New York City,
so I want a good alarm system, and also would like to add a CD-
player. I’ve asked around, but everyone I talk to either has an
ax to grind (i.e., they’re trying to sell me something), or
doesn’t know Jaguars specifically.
So: Is the factory-installed alarm system good (i.e., cuts off
the engine, etc.), or should I get Clifford, LoJack, or something
along those lines?
Also, what’s a good aftermarket in-dash CD-player that won’t ruin
the look of the dashboard?
