My understanding of smartlock keys is that no, they are not unique. However the code that is programmed into them is. This way if you had your keys stolen, you can de-programme them. Then after purchasing new replacements, you just program the new ones to your car.
This way, if you lose a key you can make sure that it isn't used to start the car if it is "found" by somebody else.

Smartlock keys are meant to be all different - the lock barrel itself has a stack of small discs (6 I think?) which make up the combination to match a particular key - ie. there are 4 types of discs: 1 2 3 4 identified by notches on their edge.
The way the discs are shaped tho, I could well understand how a worn key might manage to make various locks work - bit of a design flaw I think.
Someone has said that any of these keys will actually lock any other car - even if not the right one to unlock.
I got new door locks which came with new keys but of course were different to the ignition lock, so I pulled the ignition barrel apart and made up a disc stack of the same code as the new door locks. Unfortunately, I assumed that every lock would be a combination of all four discs but they're not - so I actually had to get hold of another old lock from a wrecker to get the one "digit" I was short.
And to this day the boot is still the "old" code as I haven't got round to changing it.
Of course about 2 weeks after this I discovered that Ford sells a complete replacement lock set set which includes locks for both front doors, boot and ignition (and new keys of course). Why the friggin dick I ordered the door locks from didn't say anything about this I do not know (it was a Ford dealer spares department) - because I explained my problem to him as: "the little weather cover flaps on my door locks are gone - is it possible to replace just the flaps or do I need new locks".
I know for a fact that any Eseries key with models with the TIBBE door locks can lock any falcon but can't open it.
Sounds like yr mates key is warn to it can open an AU. But i have yet to hear about a remote pad of a falcon opening another falcon. On the Eseries falcons the key so if the grove cut is similar then theres a chance it will open it, and perhaps start it.
Remember it's only the AUII with smart shield that has a chip in the key, previous ones don't as i have got a blank key from ford and got a locksmith to cut it.

All E series cylindrical keys can lock another ford with the cylindrical key. Ive tried it on my ED, my girlfriends ED and her brother's EF and Also her sisters EF.
Im not sure about starting another's car tho.
I have also programmed my remote to open and close both my ED and my girlfriend's just in case. But to do this i needed to have her key in the ignition to do it.
Ill try and start her car with my key cos im curious. Of course this will be of no benefit to anyone as i cant say whether it started or not on here as that would be BAD.
As above, but I do know that you will not be able to open another E series with your key. Maybe there is the odd fluke with the key combination, but that's been the case with all sorts of cars, not just Fords. All the E series keys DO NOT have any sort of chip or programme in them, they are just a plain old key. I unfortunately locked myself out of my XR8 at work once, and as our company has mostly Falcons for company vehicles, I treid every key I could get my hands on. They ranged from EB II to AU II and not one of them opened any lock of any type. I had been told that all the locks in the boots of Falcons were the same, and this is not the case either. So I wouldn't panic if I was a late model Falcon owner, the cars are secure, and even if you did get in, you'd never get past the electronics anyway!!!!
As for Russell's post, mate, you're better off keeping that sort of thing to yourself. No need to advertise that sort of info, even if it's slightly true. But by the same token, people, don't lock valuable goodies in your car anyway!! There is always a way if someone wants to get into your car.. B*stards.
