Default Replacing OEM ECU - is dealer necessary?

I purchased an AP1 OEM ECU from another vehicle to install in my AP1, it came with lock cylinders, ignition cylinder and keys.
1) Do I need to incorporate any of those extra items when swapping ECUs?
2) Do I need the dealer to flash the new ECU to my car for it to work?

Backstory: My car was burgled 6-7yr ago, in their haste to steal my parts they left some vac-hoses and wire disconnected. CEL P0411, reconnected everything, reset ECU, still have same CEL. Test my SAI pump, it's fine & so is the fuse (or relay? I forget). We install a SAI bypass, but yet.. the code comes back without fail. After running out of culprits, we determine the ECU may be my problem as I drove it with the CEL until tags expired. I'd drive (sparingly) with expired tags but the past couple years have barely driven it at all and really need to get it legal again. I've owned it 11 years and really miss driving it as I please, driving it with bad tags is too risky to enjoy :[

Pic for grins :]

This past year I replaced my ECU with a used one from ebay. I found a local locksmith to reprogram it to work with my keys for about $100. So your options are to either swap everything out or reprogram the new ecu to work with your current key set (by either the dealer or a locksmith).
