As part of the security system is embedded in the engine management ECU (ECM) the ECU has to recognise the code sent from the immobiliser before it will switch on and perform its functions.
Sometimes when ordering a replacement ECU using the vin from the dealer it will arrive programmed with the correct code but this is unlikely with aftermarket replacements and consequently reprogramming of the system will be required.

As far as the first question, can you get a PCM with the same number, yes.
Can you discribe what happened prior to the "no bus" message?

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.

No, unless you go to the dealer. you can usually, with most car manufacturers, order a new key just provide the VIN and whatever else they ask you for

verify that you have a fully charge battery and that you have the same amount of voltage at the battery as at the starter when the key is turned to the start position. If not repair fault at positive cable either at battery or at starter. If voltage checks good. Use a remote starter and turn key to the on position and try to crank over engine with remote starter. if engine cranks over. You have a defective starter solenoid and starter must be replaced.

the immobilizer system is in lock mode. Sometimes cycling the key
will bring it out of lock mode. Turn the key to the on position for 5
seconds, then off for 5 seconds for 5 times or more then recheck.
If
that doesn't work you may be able to reset the control unit by removing
both battery cables and touching them together for a few seconds. This
procedure drains the control unit capacitors and they revert to their
prelearned values.
