Thanks for the additional info.

We ended up selling the green disco 2 to someone who wanted the frame and xfer case for another offroad build (custom series build). We sold the ignition components separately to someone who needed to replace theirs.

We also bought a Nanocom and used key that we were able to successfully reprogram. The Nanocom has a miserable user interface, but it worked well to program the used key and adjust some settings. It'll definitely be useful when we eventually need to do some deeper troubleshooting.

We are also going to pick up a RV4 key for an emergency backup/spare. We're having trouble finding people willing to cut the LR key. Although truth be told, we haven't looked all that hard yet. The one hardware store we asked declined...

We previously replaced the pot metal pin with the stainless steel upgrade as a part of our baselining (we had to replace four of five actuators to get all the locks working, so we were already in there and it seemed like a no-brainer to upgrade it).

 

It is possible to swap the ignition from the green vehicle to the white vehicle to get a spare key, but it may not be a straightforward process. In addition to the ignition assembly, keys, and driver door lock, there may be other components that need to be transplanted, such as the remote lock ECU and immobilizer/security module. These components are often paired with the specific vehicle and may not work properly if transplanted from a different vehicle.

If you do decide to go ahead with the swap, it is recommended that you consult with a professional mechanic or locksmith who is familiar with Land Rover vehicles to ensure that all necessary components are transferred and programmed correctly. This will help to avoid any issues with the vehicle's security system or other electronic components.

Alternatively, you could consider ordering a key and programmer from Remote Key in the UK and using a Nanocom to reprogram one of the keys to match the white vehicle. This may be a more cost-effective and reliable option in the long run.

 

Thanks. This information may be helpful to future searchers.

We sold the ignition and keys to someone who needed them, removed parts we wanted, and sold the green car.

We bought a nanocom and have successfully programmed used keys for the white one. Highly recommended tool, despite it's high cost for the DIYer.

 

Just to clear this up, if you don't have or care to have keyless entry you can swap the ignition switch with no issues/nanocom or any scanner.

Our drivers door lock cylinder froze/stuck, luckily in the unlock position so she didn't have to crawl out of the rig.

Hers is a 99 and we have a parts 04 with 3 spare keys.

I took the door lock and ignition switch out of the 04 and within an hour she was good to go again.

I was anticipating settings off a security alarm and needing to overnight a nanocom to fix the issue. Instead I got to get inside in time to watch the pens lose to the hurricanes.
