Ignition/door lock question?

sorry for the misinformation on my part.

I assumed they weren't the same since both my own and my buddies car don't have identical keys for the doors and the ignition. Obviously I was wrong and both our cars must have had some door locks or ignition switches replaced during their lives LOL.

Again, sorry for the misinformation and I stand corrected.

It is very common for an ignition lock to have been change over the years.
