I'm pretty sure there will be some re-programming involved.
At the very least your key fob is linked to it using some elvish magickery I think.
Also it returns your VIN number when asked and I'm guessing it doesn't read it from your windscreen, in which case that might need updating as well.

Biggest issue is immobilisation
If you get a 2nd hand engine ecu also get the keys and immobiliser ecu to match then swap the chips over inside the existing keys
Plus why so you think ecu is knackered?

Hi, can I ask, why would one have to change the chip in the key? I have changed my ECU, key barrel and immobiliser ECU but my car still won't start. Wounding if you could shed more light on what I really need to do

As the chip in the key talks to the immobilisation ecu and says it's a valid key and will allow engine to start.
The key needs to match the immobilisation ecu otherwise it won't start
What year is your car?

It's a Vogue 2002 4.4. So from what you have said I don't really need to change the chip in my key because when I got the ECU I got it with the same key, key barrel, and immobiliser. After putting every thing in the car I tried to start it but it cranks but still won't start. I then found out that my old key is still locking and unlocking the car.

The remote locking is separate to the immobilisation on a 2002 Vogue Range Rover and until you program the new key to the car for the locking that won't change - you can do this yourself - can't remember the process off the top of my head - but I'm sure a Google search will bring it up.
Which ECU have you replaced? The Bosch silver unit in the under bonnet black box?
It could be the immob and engine ecu needs syncing which can only be done using diagnostic equipment
Why are you replacing the immob etc?
