Getting a spare set of keys Options

[sarasa]

I went through my manual the other day and it said to get keys from the dealership, I'd need the key number. I bought my car used back in April and all I received was a remote and one single, Toyota key. I did get a spare made at Lowes that sometimes works if I turn it upside down. I tried to get a better one made at a different location, but it would only unlock the door and not start the car. We cut three keys and tried recutting two of them with no success. Would Toyota be able to cut me a key based off of the key I have or find a master key similar to it?

I am nervous of losing my key but without the number I don't know if they would be able to tell what kind of key I have. Plus why isn't the other shops able to cut my key? If it is because of excessive wear on the key, could it damage my car or locks if I keep on using it? I thought it was originally because one of the hills on the key wasn't the same on the other side, but I met a 7th gen Celica owner and his key was the same way.

I have a '97 and I think it's a ST.

It does make a difference. The dealer doesn't copy your current key, they look up the key code and grind it as it was from the factory. The key is a little "stiff" because the tumblers in your ignition and doors are worn, so the key needs to be broken in.
