Spare key
After having my CJB replaced last week, my spare key now no longer works with my car. I rang my local stealer, and they said I should bring it in and they will reprogram the key. When I asked if they could come and get the car and do it, rather than me taking a couple of hours out of my day, they said no. I pointed out that it only needed doing because of work they had carried out on the vehicle, and it was under warranty. They said I could do it myself by "starting the car and driving around for a few minutes". At this point I pointed out it could be rather difficult to start the car with a key which didn't disable the imobiliser. "Hmm.. well just try putting the key in the ignition for a few minutes then", they said.
I know this will recharge a dead key, but will it also "re-pair" the key back to the car?

can't see it working the 'old' Ford way was to put in a valid master key, then replace it with the new one within 20 second or so....
I'm fairly sure that IDS / WDS is needed to code the D3 keys into the system

Print this out for your dealer....

Each ignition key has a unique identification which is determined by the transponder in the key head. Every RF signal from the ignition key contains the identification code and a rolling code. The CJB (central junction box) checks the codes and only responds if the signal is from a valid ignition key. During vehicle production, the identification code of each ignition key supplied with the vehicle is programmed into the CJB (central junction box) , and the rolling codes in the ignition key and the CJB (central junction box) are synchronized. A total of 30 'slots' are available in the CJB (central junction box) software to allow for replacement and additional ignition keys. In service, T4 can be used to communicate with the CJB (central junction box) for the following:
Identify ignition key allocation within the CJB (central junction box) .
Enable new ignition keys.
Disable ignition keys.
Re-enable a previously disabled ignition key.
If the vehicle lockset is replaced, the keys supplied with the new lockset must be enabled and the old keys disabled.
If the rolling code of an ignition key loses synchronisation with the CJB (central junction box) , the remote operating functions will cease to operate. Synchronisation can be restored by starting the engine with the unsynchronized ignition key and allowing the engine to run for a minimum of 6 minutes.

So it'll need to go back to the stealers then (if I read that right)...
I knew somebody like TFC could save me sitting in the cold for a few minutes.

They've clearly done something wrong. Before the CJB was replaced, they should have downloaded the VCF, which includes the CJB settings. Once the new CJB was installed, they should have reloaded your previous settings, including the spare key details.
In fact, if they'd been on the ball, they'd have asked you in advance to make sure your spare key was with the vehicle so that they could check the configuration.
