It sounds like the security module needs to be replaced. Does the engine start up and run? Here is the location of the module and the replacement instructions below. Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.

It sounds like the security module is bad. To be sure let's check out this video which will help confirm the issue:

Being a 2006 you are looking at buying the parts to replace the damaged ones as well as new keys. The aftermarket bypass systems usually cause far more problems than they claim to solve especially on this type of system. Then add on a remote start as well and you are getting deep into the barrel of worms.
The good news is that it isn't that bad.
Step one will be to get a new SKREEM module and lock cylinder, that is the part with the antenna that circles the switch. Now visit a locksmith or have one come to you, with your title and registration and drivers license. With those they can contact the factory and get the proper key codes to cut the new keys. Then the replacement cylinder can be pinned to match the lost keys. That way you don't need to replace the rest of the locks. Those parts get installed and they can program the replacement SKREEM module and the keys into the system. I would call a few places as well as the dealers and see who has the better deal. Remember that the smiths will usually charge more to come to you but that with the dealer you are looking at tow bills.
Unfortunately there are no shortcuts or ways you can program the keys yourself. As for the lost keys, as the new keys are programmed in the old ones can be erased so that even if they do turn up they will not work.

Thank you for using 2CarPros.

Well you can use the used parts but you still need them programmed into your vehicle. They are not a plug and play system. The various modules are registered with and through each other and changing any of those parts requires the reprogramming.

This issue started after you replaced the ignition switch? Did you replace just the cylinder or more than that? Sounds like your SKIS (Chip in the Key) is not programmed any longer. Refer to the second attachment circled in red.

Review this info and let me know if you have questions. However, I would get new keys programmed to the vehicle and go from there.

Yeah. Unfortunately the dealer is going to have to go in and deactivate the alarm and then diagnose it. I suspect the key is the issue but they will be able to determine that. You are correct that just turning the key to the on position is what disables it. The fact that this is not happening points to the key or the sensor in the ignition.

You cannot bypass the alarm easily, have you tried a hard reboot of the system? Remove the negative cable from the battery and hold it to the positive battery terminal for one minute. This will discharge the capacitors and let the system reboot. Here is a guide that can help:
