Default SDD v169 XF facelift battery disconnect issue. CJB auxillary junction box immobilize

I am having trouble finding "immobilization" function on SDD v169. I am having the classic 2015 XF facelift battery disconnect issue with washer pump, central locking, and keys not recognized. I am able to run SDD v169 full online with a subscription, mongoose plug, laptop plugged in, power supply unit at 13.5v 50A. I was able to get to every feature described in many forums about updating and running the "configure existing module" for the KVM BCM and BCMB(Central junction box, Auxiliary junction box and Keyless vehicle module). As well as being able to run the battery replacement option. But all the previous posts are from people running older software with the "immobilize" feature under the security section of service functions in SDD.

I was able to do all the steps within SDD v169 with turning the car on and off and completed every service function, recommendations tab and even extras tab. I ran through SDD with no problems or failed tests. But my problems still persist as if nothing changed with the car. I was curious if in the new updates for SDD they they maybe switched "immobilize" to "configure as new module"? Or if it is safe to run configure as new module under the service functions tab for the CJB and auxiliary junction box in hopes to fixing the problems described. There is also no corrosion on the CJB as some people describe with leaking washer power pump. I am certain the issue is within SDD, I have spent about 7 hours in SDD updating so many modules in the car and running almost every possible test relevant to the issue. I just am at the point where either I just cant find the immobilize feature or I need to configure modules as new is the last thing I haven't tried.

Only thing I could find;Issue one most common:

Car won't lock after battery disconnect. This is solved via immobilisation in SDD.

Issue two less common:

Key not recognised at all hence no ignition, immobilisation not possible.

This is done via cluster reprogram as it will bypass the key sequence, turns ignition itself and do the immobilisation at the end.

This will also update cluster to latest software, bonus.

Please don't throw suitcases of money on KVM module/keys and what not, I've never seen a faulty KVM module.
