Im trying to reset the alarm system in my 95 Jaguar XJS NOT

Customer Question

Im trying to reset the alarm system in my 95 Jaguar XJS NOT the XJ6 I cannot get it to shutoff
JA: Have you tried locking and unlocking the driver's side door using the key itself?
Customer: Notnthe key itself
JA: Are you fixing your XJ-SC yourself? What have you tried so far?
Customer: I just changed the battery in the key fob and then went out and tried to see if it was working and then all of a sudden the alarm went off..then I immediately tried to put the key in the ignition and turned it to position 2 and and that didn't do anything..also read where yor supposed to push the valet button in the console..but this car does NOT have a valet button..I disconnected the batter but that didn't work either
JA: Anything else you want the mechanic to know before I connect you?
Customer: no I need someone who knows about 90's model Jaguars

I have heard your supposed to press the valet switch in the console, but this car does not have a valet switch in the console.
Expert:  TIM MOHR replied 10 months ago.

not the ignition, the door lock, you need to use the key in the door lock, not the ignition.

Disconnect the Negative Battery Cable
Open Driver Door & LEAVE Open
Turn Ignition Switch to ON & LEAVE ON
Reconnect the Negative Battery Cable
Alarm may sound for a few seconds
When it stops Start Vehicle
IF the Alarm does NOT stop, then you will need use of a working, Programmed Remote or Jaguar Dealer Scan Tool

Let me know what you find
