2008 X350 TIBBE Keys

[DMG47]

I have a 2008 x350 Daimler super 8. Imported from Japan in 2017. One set of keys. Got the key code relating to my VIN number and does correlate to the original key (so locks have not been changed). Had cut by a very experienced locksmith used to dealing with Jaguar keys.
The key will open the boot but not the doors or ignition. Does the key transponder need to be programmed to allow it to turn in the door / ignition lock?

Update - it would appear that the key will not turn in the lock(s) door or ignition if it not completed with the fob - transponder programmed or not! so if you have a new blade part cut you must fit it into the fob to operate the locks! the only lock it will operate without the fob is the boot!

As you have discovered, the keys contain a transponder, and the car's security system must be programmed if the transponder is changed. The transponder is in the plastic bit that's irremovably attached to the key. There's also a separate transmitter, powered by a lithium cell, in the detachable part of the key. (It may not look detachable, but the gentle application of force will separate the two parts at an invisible seam.) That also needs to be programmed when changed; in this case it's the door lock system that needs programming; I think it's separate to the security system - not that the distinction matters in practice.

Different countries use different wavebands, so a Japanese import key may be different (and probably breaking some laws about waveband use) to a UK key. If you want to replace the transmitter you need to specify which country - presumable of the car, rather than key - I don;t know if you can change the car's country code settings.

Getting the system reprogrammed for new keys seems fraught. There's a sequence involving flashing the headlamps and holding various switches on when turning the ignition on, but it seems not 100% reliable. There's an alternative using either the Jaguar ODB-II tools or some of the more expensive DIY ODB-II tools, but even they are not 100% successful. I lost one of my fobs, and had to take the replacement to the dealer to get it programmed. They had problems until they replaced the (new) battery in the fob; I wonder if there are different voltage batteries in the same lithium form factor.
