Cant turn the ignition to start the car HELP Needed

just Wondering what are my options to fix it.
for the last three years every now and then the key would not turn till after playing with it and it will turn and start the car.
and now cant turn the key at all.
it only turn to a small click and that's it.
the key looks worn and did get new cut last year  but it didn't help.
i used D/W40 and graphite and still nothing. i called a locksmith and told me it could be the ignition switch but not sure.
just wondering if anyone had the same problem.
thanks  
 

No sw20 don’t have it.
Still can’t get it to turn

I’m trying to get the key code but Toyota can’t find it.

Does it matter if I get the code from drivers door.
I read a lot people get it from passenger side.

The reason I ask my passenger door has a different key.

Now I’m confused?
Car came with two keys
One key starts the car and work on drives door.
And the 2nd key also starts the car and passenger door, boot. Glove box.
Does this mean the 2nd is the original key

It will be interesting to read whether a new key works in an old/worn switch. Especially since they are not cheap. Fingers crossed
