Default Mistakingly put unprogrammed key on ignition now no starr

I got a key cut yesterday for my 2007 Yukon Denali 6.2 . I was changing the fuel injectors and went to try to start but I used the unprogrammed key now the trick is in antitheft mode and the original key won't work anymore now. The passlock symbol is blinking.

I know on the older vehicles you could turn the ignition on with a good key, leave it for 10min, turn it off, then back on for 10min, do that 3 times total and then attempt to start the vehicle. It should relearn the key. You may want to hook up a battery charger while you do this.

Ok I am trying it now. I'm on the second cycle. After ten minutes the light doesn't stop flashing. I'll see what it does after the third cycle

would unplugging sensors under the hood and injectors with battery plugged up cause this state? im so sad. i cant start my truck

Just to update, I had it running the same day. I learned when putting an unprogrammed key in ignition it induces tamper mode. I locked the truck And armed the alarm and let it sit for twenty minutes. When I came back afterwards it started. Now my steering wheel is vibrating and I smell my front brakes burning. It's like it's one thing after another with this damn thing. I might sell it but I don't know if I'll be able to find another black on black Yukon Denali again.
