ignition lock cylinder

to make a long story short I am a moron. I just purchased a 1995 neon loved driving it for the two days I could. The problem is I have lost the ONE and only key that I had for it. I called the dodge dealer and was told as long as the ignition lock cylinder hadn't been changed he could make me a key and hope for the best because we have no clue if it was changed or not. My question now is if it has been changed and i have to replace the unit how hard is it and can anybody give me very detailed idiot proof directions on how to switch it out.

Thanks!!

It's really easy to replace. If you need detailed instructions, I can provide them to you. But find out first if you need to replace it.

Im praying that I don't have to replace it. I have ripped my house apart looking for the damn key. I shouldn't hide things on me. The Service guy at Dodge told me that ignition problems were common and chances are it may have been replaced in that case Im SOL I have read instructions on how to remove and replace however without a key i can't turn it to the on position.

Do all the locks match? If so than it is unlikely that all of them were changed. I am not sure about Dodge but GM puts a lock code number on the lock. If so I would remove the trunk lock and get the number. Most locksmiths can cut a key using this number. If not a good one should make a key to match the lock.

Yep, one key for all the locks.

I know that, but did his lost key fit all locks.

Yes and yes the key fit all the locks, trunk, doors and ignition. So this is good news for me. Thanks all for the replies!!
