Thread: D2 No key can I use a BCU and key from another vehicle

that'd work but my first look would be to see if you can get the EKA from the dealer off the vin and ECU numbers and then sorting out a replacement fob.

Many thanks. I have the BCU and matching key (in fact 2 matching sets still in vehicles!) so I might give that a go first and report back later today. I would need access to a nanocom to go down the new fob route

first very carefully remove the steering column shrouds, have a look at whats going to be involved in replacing the key barrel, whats the potential issues are going to be if you mess up the lock mechanism and tumbler configuration. At the very least, do all the prep work for the removal of the lock mechanism for the ignition and then pay a locksmith to come and do the work.

Id suggest if you're going the route you're going that you leave the ignition lock stuff alone and only do the doors then deal with having 2 keys to operate your vehicle.

What are you doing with vehicle, keeping/using or selling?
Changing the bcu is physically straight fwd but the odometer will conflict with the new BCU.
You will need a nanocom anyway to allow the engine ECU security to talk to the swapped BCU.

Since you need a Nanocom anyway, it will be easier to sync one of your other key fobs to the BCU.
You will have to swap the BCU ECU Ignition and door locks if you don't want to use a Nanocom.

Then you still would need to look at injector codes and relevant ECU types later anyway.

Thanks for that. I intend to keep the vehicle. Getting to be complex but where there is a will there is a way - may be! As far as I can tell the vehicle that I intend to harvest the parts from is identical to my vehicle - I could change over the ECU as well. Would I still need to match injector codes to get it going?


Changing the ignition lock does not daunt me but I will try pulling one out of the wrecked vehicle first.


I will probably buy a nanocom eventually but wanted to try and get it as a group buy if enough others were available.

The Disco2 came with 2 different key frequencies. If you get a couple of keys from parted Disco2s that have the same frequency, then using a nanocom you can get the BCU to listen to the replacement key electronics. You don't need to know the key codes etc, the BCU will just work it out.

Then, on Ebay you can buy replacement blank keys with the blank cases, buy ones made by Valero who are the original manufacturer. Then get these cut to match the one that was in the ignition and swap the electronics into the new fobs.

This will fairly cheaply give you new programmed keys. The BCU will accept 3 or 4 keys only. I think it is 3.

OK changed the BCU with an identical part numbered BCU and matching key with fresh battery) - remote/alarm works but it does not turn over - I have left it for a while to get used to the IDM. If that does not work I will change over the ECU's and if that doesn't work I guess it is nanocom time - anyone in Darwin with a nanocom??
I have got the ignition lock out of the wrecked vehicle - was not difficult.


Thanks everybody you have been great!

And now it turns over but does not start - has probably been sitting+++ and I have flattened the battery. Should I change the ECU over?
