My 2000 P38 4.0 has one original key that works perfect. It looks like it's been through a war zone however. I fear for its future.

My spare key I think is a copy based on a disco key (not the flippy type) but it doesn't have any buttons so you can use it to open the car using the blade, but if you try and start the car is says engine disabled.

I'd like to get a new key, mainly as I find having one proper key a big risk, but the only ones available are boring fixed blade key types (yea I'm being a bit of a tart).

I saw on youtube the other day (samcrac youtuber) where he bought a machine that could basically copy the immobiliser chip and RF transmitter of pretty much any key.

Does anybody know what the reason is why I can't buy a spare L322 key for example, and someone with such a machine can't programme it using my current working working key? I've tried asking a few key copiers and I've got a no from them, but no explanation.

Alternatively, I've been thinking about disabling the immobiliser and EKA just to reduce the risk of having a problem with the BeCM. Does this open up any opportunity for getting a half decent looking key for it?
 
you can disable immob and eka, its not a bad thing to do, done it on mine. to rely on the blade in the door lock isn't ideal as the locks arent exactly 'robust'.
Classic Rides are known to do new keys that will work, https://crnw.co.uk/ or your dealer should be able to get one. L322 uses different tech

I'd guess it's because it uses a rolling code so the copied key would be out of sync.

Turn off the EKA and immobiliser and the car will work fine with just the key blade. Different FOB's may operate on slightly different frequencies and be set up for a different data stream so are unlikely to be compatible.

MrSporty on here can refurb your key. Of you can get a new case and buttons on eBay and do it yourself.

You can clone a P38 key but as the code gets incremented each time you use it it throws the other one out of sync so you'd have to resymc each time you swapped keys. Embedded in the code string that gets sent is the key number. I think a few people know how to change this, including MrSporty and possibly Classic Rides North Wales. Rick-the-Pick probably can do it too but I don't think he bothers with keys.

As Mark says, turn off the EKA in the BECM using a Nanocom or similar and you can just use the blade. However, you might be using the memory seat option in which case 2 working fobs would be nice.
 
Les at Classic Rides can create whatever key number you need, so the new one doesn't conflict with existing key. Unfortunately he does not do flip keys.
 
You can buy a genuine replacement key fob from a Land Rover main agent at a cost of about £250. They just need the registration number or possibly the VIN. They may ask to see the V5C & photo ID but didn't when I bought mine a couple of years ago from Lookers the JLR main agent in Colchester.

Just hope the BECM has not been changed, check the VIN held in the BECM matches the one in the log book. Also make sure if ordering OEM to get the right FOB number, you cannot use 2 with the same number.

Bl**dy hell. The last key I got from the dealer was £150. That must have been around 2012. The Brexit effect?!
