I would expect will need to have the OBD read and reset from there

You need to have it towed to a shop, you likely fried the electronics.

Do you have tools and skill to do the bypass?

When the thief broke away the switch, he most likely broke the part that reads the code from the key. The fact that the car starts for 3 seconds and then stalls is a tell tale sign that the antitheft has failed. The injectors actually turn off because its not reading that code properly. You have 2 options. Replace the ignition with an original OEM ignition and the have the dealer reprogram it to accept the key signal. Or bypass the antitheft entirely. I'd suggest the bypass just due to the cost of dealer fees and OEM parts. But its all up to you. PS. You can install the bypass yourself and drive it that day. Here is a link explaining the system and gives you some options for DO IT YOURSELF fixes.

Your VATS security system is failing. Quick fix, turn key forward 2 clicks till right before it starts. Leave it for 10 minutes. (no less) turn back key and then start again. should be fine. Getting these fixed is about 800 bucks. They sell a bypass for 200 online. I did the "10 minute trick" for over a year, till finally the Computer went. I ended up doing the 200 dollar bypass. Works great, no worries.
