New newbie meat here.

[why?]

Odds are you have the original key. Many Yaris never had fobs, security systems, or power locks of any kind. They were extremely rare expensive options in 2007.

Just get the system you have put in correctly, it should not cost much to take it to a place to do it.

If you really think your car originally came with something like that, a normal key would never actually work to start it, because the first thing Toyota did was install immobilizers into the cars, which means you had to have the correct key to start the car.

I know for a fact the key I have is not the original key because 1) it doesn't have the Toyota symbol on it and 2) I actually have a security system in my car. On the center console near the emergency brake there is a tiny square that says "security" and it has a tiny little red bump above it that I'm assuming is a light.

This is what it looks like.

Because of the key I have now, I haven't even seen the security light come on at all. Like I said, it's lying dormant. Maybe I just got the 2007 Yaris that's special and actually has a security system unlike other ones? I don't know, but either way.
I'm thinking that if I get a new FOB key cut and programmed to my car I could use the security system. If I'm able to do that, I'm assuming the key I have now wouldn't be able to be used, correct? That could prove most useful.

If you have that security light assembly on the center console, then your Yaris has the Toyota RS3200 TVIP alarm (which is a dealer installed option).

So, now you just need one of the keys with the remote to get it working. There are four different key part numbers for 2007, so if you want to PM me the VIN for your car, I can verify which part number you will need to purchase.

What Scott said. Yea, special is a way of putting it. Those things were extremely expensive options.

Usually those vehicles also had engine immobilizers, which means the key had a chip in it so without that one key the car would not start. Odd that your car did not have that.
