2003 Jaguar S-Type, programming a key fob

Apparently not. I found this super simple procedure to reprogram the remote keyfob. Fingers crossed it will work and save you money -
Jaguar Type Information Program Remote Key Fob

it needs programming using suitable diagnostic equipment using jag software i.e. jaguar wds. or ids.i don't think there is another way to do it.

Programming or pairing a new remote Keyfob for the X Type is a very simple job that will cost a substantial amount if it is done by Jaguar. It's annoying but this may need to be done if your Keyfob battery has been allowed to go flat, or the car battery has been removed for any length of time.
Follow these steps exactly and you should have no problems, pairing old or replacement Keyfobs for your car.

1.)I would recommended that you ensure all key fobs are fitted with new batteries. ( Click here to see battery replacement guide).
2.)Get in the car and close the drivers side door.
3.)Put the key into the ignition and turn to position I.
4.)Wait 5 seconds
5.)Turn the key quickly to position II then back to I four times.
6.)You should hear a single chime.
7.)Remove the Key
8.)For each Keyfob in rapid succesion. Press any single button on the keyfob you wish to pair, you should hear a chime as each Keyfob is paired with the security system. After the chime do the next Keyfob.
9.)Check operation of each Keyfob.

Your key fob needs reprogramming, and yes the alarm will go off when you open the door, but you have enough time to put the key in the ignition which will prevent the alarm sounding. Car is usable until you get the fob sorted by locking and unlocking using the key.

Sounds like it lost it's program. Go to the Jag dealer and get it reprogrammed.

try reprogramming.process widely available on these sites. 're-programming x-type key fobs'

The switchblade key would need to be compatable with your ignition switch barrel. Only normally available from jag dealers who check the Jag owners register before supplying you a replacement.
The older type seperate fobs could be programmed by switching the ignition on and off 8 times (allowing all functions to settle) and on the 9th switch on - press a button on each fob and then switch off. to test use a good fob to lock the car then try the reprogammed fob to unlock/lock. Sometimes this works first time - sometimes needs a couple of tries.

could be static build up in remote dealer has foam pads that can help eliminate this

Your key FOB is easily programmed by yourself without the need of computer, here is how: Push and hold the trip computer button on the left stalk, while holding the button turn the ignition ON and OFF several times untill you hear a confirmation tone from the glovebox area, when the tone is heard, release the button and remove the key from the ignition, immediately after push any button on the Key FOB and you'll hear another tone that confirms the programming.
