Yes you definitely want to jump on that or it will be a bad deal if it locks up.

Here are some hints:
-tell the rep you want the vin-matched version, they do sell a generic for a few bucks less but it won't match your doors.

- the rep might tell you the cylinder comes with no key. This is wrong, it comes with one key. Extras are like $15 apiece. I ordered 2 thinking that was all I was getting. I received 3, which turned out good because now all 3 drivers in the house have a new key.

- pulling the cylinder is easy, you will need a "jumbo" paper clip. When you get your new cylinder check out the outside of the barrel, you will see a little spring loaded tab. You will notice that the tab lines up with a slot in the front of the cylinder. To get your old cylinder out, take your key and rotate to somewhere between positions 1 and 2, you will see the notch line up with an internal hole. Now take your unbent paper clip and insert it in the hole. You should feel the tab pushing out of the way, which allows the black ring to turn. Unscrew the black ring and withdraw the old cylinder.

Slip the black ring over your new cylinder and insert the new key. Turn the key so the slot and locking tab are lined up and slip in the paper clip to be ready to push the locking tab.
Put the new cylinder in the chamber and begin to screw the black ring on. Eventually it will get hung up, now use the paper clip to free the tab and allow the ring to turn some more.

Stop tightening when you get close to the end of travel of the screw threads. Then pull out the paper clip and turn the ring backwards a partial turn until it locks in (the tab jumps into the groove in the black ring).

Turn your key back to 0 and pull it out, verify the steering lock works. Now put the key back in and start it up!
