Jusy changed battery on key fob alarm keeps going off and car wont un lock
I recently changed the battery on my key fob for my ssanyong rexton. I then did the following for the key fob to make it work. 1. Enter vehicle and close all doors.
2. Put seatbelt on (or clip it into the buckle) to shut the warning buzzer off.
3. Put key in ignition, turn to run position but don't start it.
4. Press and hold both buttons on key fob until red light on fob stays on. Then let go of both buttons. Then pressed the alarm button then the panic button, somthing like that. To be fair the button sequence after the red light came on is a bit vague. The alarm was blaring so i was happy when it just stopped.

SOURCE: key fob will not undo
If you don't have one that works for the vehicle now, you'll have to take it to your local dealer to have it programmed to the vehicle. Some will charge for this, some will do it at no charge.
If you do have a remote that is programmed and working for the vehicle, then the following steps will allow you to program another remote:
1. Enter vehicle and close all doors.
2. Put seatbelt on (or clip it into the buckle) to shut the warning buzzer off.
3. Put key in ignition, turn to run position but don't start it.
4. Press and hold the unlock button on the working key fob and hold for 4 seconds, then also press the panic button.
5. Release both buttons and you should hear a single chime to indicate it is in program mode. You have 30 seconds after the chime to program any additional remotes you want to program.
6. Press and release both the unlock and lock buttons simultaneously on the remote you are programming. You should hear another single chime.
7. Within 4 seconds after hearing the chime, press either lock or unlock button on remote that you are programming.

I am having trouble also but I need to know how to disconnect the alarm. I would appreciate it if you could help me out seeing that you have disconnected yours. Thank you

This does not sound like a fob fault - but a locking control module fault , either in the hardware or software of the unit. Get it checked at a Jaguar dealers. When unlocking using the key - as soon as the door is opened you should hear a chime sounding inside the car - this is a timer counting down to sounding the alarm. If you put your key in the ignition as soon as you open the door the alarm should not go off and the chime should stop. If it does not this again points to a fault in the locking controller.
hope this helps - good luck.
