I have seen a few of these lately pop up and may be the start of a pattern failure. The complaint may be that the car just will not start and has been towed in with code B2784 Antenna Coil Open/Short. Check and see if the immobilizer light stops blinking when the key is inserted into the ignition switch. If this code is set, then it wont. It's a pretty straight forward repair to replace the coil/antenna.
