Ignition lock cylinder

I ordered a automatic ignition lock cylinder for my car, it's gonna arrive at my house in a day or two, I'm gonna pull out my original ignition lock cylinder and compare the two to see if there are any differences but honestly I don't see how it could be different. It's just a lock, theres no electrical connection on the cylinder (I've already taken the original out and inspected it closely, but put back in the socket, I can just as easily remove it again.) I'll see what I get and then make a decision based on the options and whether or not it's worth the cost. I'll have to consider the fact that I will have two sets of keys for the car. (One for the doors and trunk lock cylinders, original to the car), and then another set of keys for the new ignition lock cylinder to start and drive the car. I'll post and update if I can and verify that it works.

UPDATE: So I received the new automatic ignition lock cylinder in the mail, I took out my original ignition lock cylinder (manual), and compared the two very closely. I've come to the conclusion that I will keep my original lock cylinder. I've figured out the technique to getting the key to turn, just takes a little pushing and pulling at the right intervals. I put the new lock in the housing to test if the lock turned any more smoothly than my original lock. I can't seem to tell any difference. When I compared the two locks beforehand I noticed one slight difference. The original (manual lock cylinder) has a brass piece that the automatic lock cylinder does not have. I don't know what the purpose of this brass piece and do not know what the long term effects would be without actually using the new lock in the car. But I can confirm that yes it is possible to use an automatic ignition lock cylinder in a manual transmission car. I chose not to use the new ignition lock cylinder because it didn't make any difference in the smoothness of turning the key. Another thing to keep in mind is if you do use a new ignition lock cylinder, you will have two sets of keys for the car. (One key to the ignition and another for the doors and trunk). If anyone wants to have all lock cylinders match one key, you would have to take all the lock cylinders from the doors and trunk out and take them apart and rearrange the tumblers in the correct order so it sits flush with the new key. You can also grind down the tumblers to make them sit flush as well. Just in case anyone else has to replace their ignition lock cylinder and have the same key open all locks. There's videos on how to re-key lock cylinders on you-tube if anyone has to replace the ignition lock cylinder and wants one key to match all locks. Hope this helps anyone who ever comes across this scenario.
