maybe this will work.
The specific sequence to enable security system programming for 1993 and 1994 XJ6 is:

Ignitition key off
Security switch )in center console) on
Ignition on, position 1
Security switch off
Ignition off
Toggle security switch 5 times.

At this point, you should hear a tone which notifies you that the system is in programing mode and you could program a remote, if you had one. My guess is that you would be able to start the car at this point.
