The original TDDS Theft deterrent system doesn't have a keyfob.  in order to disarm the system the door 
must be unlocked with the key.  That switch disarms the system, and the system must be disarmed before 
the door is opened.

Why the headlights poped up after the knock sensor rewire, and not before...  Maybe something that was 
disconnected before became connected.  I don't know.

In any case, the root of the problem is that the theft deterrent system is not working.

The easiest and cheapest solution is to purchase an inexpensive aftermarket alarm with a keyfob and 
keyless entry.  Install this properly, and have it's unlock output also trigger the TDDS disarm circuit.  
This will resolve the problem.

Alternately, you can buy a new key cylinder from Toyota.  With the VIN number they can get you one that 
will match the factory key code. I don't know what this will cost, but I'll bet it's not cheap.  Ask 
though, sometimes it's not as bad as you might think.
