Re-keying a '06 BCGT
I just returned from the local Bentley dealer with the intent to have new factory keys coded to my car. The dealer was not successful reprogramming the car for the new keys as the Nav-TV Bentley-HUR is blocking the reprogramming process. The service manager says there may be a possibility of cloning my 1 original key to the 2 new keys. Apparently it can me done to some older Ferraris. Can anyone advise on what I can do? I am into the new keys to the tune of $755, and I really need more than the 1 key that I have.

Hello @jslamin ,
As I do not have a Benhur I can not comment as to it causing the issue with programming the new keys, I will say that if the BH does not have full functionality as to picking key numbers/names and or guest as a user tagged to each key, that most likely is your issue, do you have your original head unit, being that you are in mass, I would rent (haha) you a original head unit to use for key programming...
Or you could pull the KESSY module out from under the carpet on the driver's side floorboard and unsolder the 93C86 eeprom chip and read the SKC = secret key code with carprog ($60) and add a zero to the four digit pin number to make the five digit pin needed to program all the keys with Ross-Tech ...
It's a job for someone who does electronics.
I will go into more detail if you choose to go that route of programming yourself..

JHS, I do have the original head unit. Reinstalling that, getting the keys programmed and then swap back to the NAV-TV unit is an option with many hours to accomplish. I will do that if it is the only option. But my core question, can Bentley keys be cloned outside of the car from the original key? Is the chip in the new keys rewritable?

As I was told and have seen, and as you have a 2006, most likely with the newer 2007 style keyfobs, so, those keys are write once /read always, and not rewritable, BUT that is not so much the issue here, you now have 3 keyfobs, 1 original, and 2 new, the head unit is looking for keyfobs 1 through 3 for each user, and each user settings, so if you clone all 3 keyfobs the same, then no matter which keyfob you approach the vehicle with, it will always see all 3 as the same person or keyfob, not sure that matters for you, but it's kind of a waste for spending $$$ on two new keyfobs, and as far as the cloning, I have only heard of cloning older Audi keyfobs to the Bentley, but then the use of push button start and keyless entry are gone..

The Ben-HUR does have key selection ability, but I can't think *if functioning* it would interfere.
<Edit for clarification> I know that my Ben-HUR is not functioning correctly and is putting all sorts of **** on the bus.....
Swapping the original head unit in shouldn't really take more than an hour from what I've read.

Unless, does the BH have you cut any of the original wiring harness in the dash for installation ??

As you have to remember, there are two separate applications of the keyfobs, one is for the use of the buttons on the keyfob, the other is the keyless entry and push button start side of the keyfobs, one could program the remote side, and gain access into the vehicle by way of pushing the buttons on the fob, BUT not be able to keyless entry the vehicle, or even keyless start the engine if not properly programmed.

Again, I can not confirm as to the cloning, I have heard/read it's possible by a guy in NY, but when I questioned him as to full functionality of the keyfob he stated that I would loose keyless entry and push button start...

The story continues; I found a car locksmith that has been successful in cloning Bentley keys. He came by today to do the job. The first thing he found was the blades were cut to some car that is not mine. But he said that the codes in the new keys matched the 1 original key that I have. No problem on the incorrect blades as he cut new blades and reassembled them to the new fobs in minutes. Within 1 hour he has completely clonned my new keys and assembled the correct blades. All functions work in the car. I now have 3 individual keys that can hold all of the pre-programming info for seats and steering wheel etc. For those that need this done in metro Boston contact Paul's Affordable Keys in Pembroke, MA.

I bought the car used from a Bentley stealer in Chicago in 2015, and they failed to tell me that there was only 1 key. I drove it for the past 5 years on that 1 key. I purchased 2 new keys from my local Boston stealer recently. I now have 3 individual keys that all work as new factory keys.

So when you recently purchased 2 new keys from your local Bentley dealership, you ordered the keys by your vehicle identification number (VIN), correct, if so, that likely means that your driver door lock cylinder has been replaced at some time with a different matching key-blade, does that single key you originally received work to lock the glove box or the pass-through to the boot, or do the 2 new from Bentley key-blades work in the GB or PT ?
Just to note, the ignition key cylinder does not use any tumblers, so any vag key-blade will insert and turn the cylinder, you could even just turn it with a flathead screwdriver...
Also, I think your use of the word "clone" is out of place here, as if he had cloned all 3 to be the same, there would be no keys seen as 1, 2, and 3, they would all be number 1 as your original key, I think that he read some data from your original key which gave him access to program the 2 new keys to the KESSY module with certain hardware and software, but not to clone it, kind of the same way I read the SKC/PIN with carprog, then program the new keyfobs to the vehicles KESSY module with Ross-Tech.
It would be interesting if he shared any info with you as to what and how he did it, or if you saw which type of equipment he used.
Did you verify that all 3 keyfobs actually are seen as 1, 2, and 3 by the saving of different radio stations, HVAC temp and blower speed, different seat positions, along with steering column height and depth for each of the 3 keyfobs ?
As the "pre-programming" as you call it, is not stored in each keyfob, it is stored in the vehicles control modules for each function, the vehicle sees the keys as numbers and sets the saved positions and settings for each key number, name, or guest as shown on the Infotainment head unit screen.
I am hoping everything works as it should for you !

The new keys were ordered by VIN.
The original key and 2 new keys operate all primary and secondary locks, GB and PT. The blades that I received from Bentley operate none of the primary or secondary locks in the car. I see no evidence that the lock tumbler was swapped.
I cannot comment on the memory as yet as I am the only driver with only 1 set of settings on the car for seats etc.
My working hypothesis is that blades are cut separate from fob and assembled prior to shipment. They must have been swapped unintentionally at the factory. Either that or the stealer just handed me the wrong key set.
The locksmith used a large OBD computer and a secondary small device that can read data of of a key. WTF cannot a dealer do the same?
Regardless, I am satisfied with the results.
The lesson here is that as far as I can see, keys can be set to the car without performing microsurgery on the KESSY.

@jslamin ,
Thank you for the response.
I am glad it worked out for you !
I understand that your situation is complete, until you let us know that when you get in the vehicle and set settings as another driver would, then we know that your approach and the person you hired yielded a 100 % working outcome, I only add the following for all here on 6Speed.
As far as you comment as to why the dealership can not do the same, they can, and it is actually much easier for them, as you ordered the keys by VIN, then the Bentley dealership would just program them for an extra fee with their factory authorization and factory tools, I think that the dealership that you went to had issues with the Ben-Hur unit, or the Ben-Hur unit interfered with the factory tools for access to programming, so your outside of the dealership approach with a locksmith worked for you with non factory approved tools, and most likely, a authorized Bentley dealership is not allowed to do so, and if they did, you can bet they would have tacked a profit on top of the outside locksmith... 😉
As far as the "micro-surgery" for the KESSY, that is what I did to retrieve the secret key code of the vehicle which in turn allowed me to program the new keys without any factory tools, BUT by retrieving said SKC while I was rebuilding my vehicle, I will always have it, so I can always add new keyfobs in the future just with Ross-Tech, or replace the KESSY module itself if ever needed, as the SKC is needed for both the old and used replacement KESSY module, as it is also needed for steering column replacement/steering column lock mechanism adaption access authorisation, etc.
I have also recently tested what I have read in the past, that the SKC can be read from one of the engine ECU'S 95040 chip for our vehicles with immobilizer 3, I recently tested this on 2005, 2006, and 2007 Bentley ECU'S 95040 chip, it worked, but it does not work for 2010 Bentley with immobilizer 4 and challenge.
