Programming FOB for 2011 Pilot

[RWS]

I purchased a keyless entry remote FOB for my 2011 Pilot EX-L off of eBay and it looked just like my originals. However, once I programmed the remote (online instructions) and had the key cut at my local Honda dealership,
it starts for about two seconds and the car dies. The locks work fine; it just won't start. Any suggestions would be appreciated. Worst case.... I can go back to the dealer and pay through the nose for them to reprogram it.

Here are the instructions I used:

1)
Enter the vehicle with the hood, rear hatch, and all doors closed. Have the ignition key and all remotes to be programmed available before entering the vehicle.

2)
Insert the key into the ignition and turn the key to the "on" position. Within five seconds, press and hold the "lock" button on the remote for one second. Release the "lock" button and turn the key in the ignition to the "off" position. Repeat this process two more times, each time within five seconds of the last.

3)
Turn the key in the ignition to the "on" position. Within five seconds, press and hold the "lock" button on the remote for one second. The door locks will cycle, indicating that the vehicle has entered remote programming mode. If the door locks do not cycle, then repeat all the steps to enter programming mode before proceeding.

4)
Within five seconds of entering programming mode, press and hold the "lock" button on the remote for one second. Release and wait for the door locks to cycle, indicating that the remote was programmed successfully. Repeat this process for each additional remote that requires programming. A total of three remotes can be programmed, and each remote must be programmed within 10 seconds of the previous one.

5)
Turn the key in the ignition to the "off" position to exit programming mode. Remove the key from the ignition, exit the vehicle and close the driver door. Test each remote by cycling the door locks of the vehicle.

sounds like the immobilizer

Definitely the immobilizer.

Programming a new key and fob are TWO SEPARATE processes. With the instructions above, all you have done is programmed the remote portion. There is still the immobilizer in the car that needs to be programmed with the new key. This can only be done with the Honda HDS tool that dealers and some locksmiths have. You cannot do this part yourself.

If not done, you get exactly the symptoms you experienced. The immobilzer disables the fuel pump so the car will crank but won't start or it will just start for a sec and then die because it is not getting any more fuel from the inactive fuel pump.
