i had the same problem try putting the security system into learn mode
open your trunk and driver door put key into second position in the ignition then open your armrest and hit the valet button (assuming it works) 5 times you will hear a beep then get out close the trunk and try to disengage alarm with the key it worked for me good luck
how do you disengage with key after
you will need the help of a local Jag specialist
