Let me add my own experience regarding this problem. We did the "hit the end of the key while in the ignition cylinder" for about a year until it decided to finally die. Thank God that it died right in my driveway. (Footnote here: I couldn't get it to turn to the start position in order to get it out of the column. What finally worked was putting my propane torch to it for about 30 seconds followed by putting in the key and hitting it a couple of times. It finally turned.) Anyway, the only place that had a replacement cylinder was the dealer who was going to charge me about $102 for the cylinder and about $30 to set it up for my existing key. Since that didn't sit well with me, I tried one more auto wrecker who, like some others, said they only would sell the entire steering column (no thanks). However, he recommended that I call a fella he dealt with that is an ACE Locksmith. Huh...was my reaction but, hey, I'm desparate, right? So I call the guy and, sure enough, he says "sure, just bring me your key and (here's the kicker) for $50 I'll have it done". I actually called him back to confirm that for the $50 that I was getting a new cylinder. He said I was. Well, I met the guy who proceeded to take a cylinder apart (he said he does this about 6-8 times a week. By the way, the cylinder he had was a new blank one which means it didn't have any of the internal guts (tumblers, whatever you call them) in it. He took my key, installed the internal pins and gave it back to me all in the space of about 5 mins tops. He also said that the lubricant to use when one of these things does start sticking is BP Blast...never use WD40. He also said that you should only have the key and maybe the remote on the key chain when it's in the ignition vs. having a ton of keys hanging off of it....the weight of the other keys eventually damages the cylinder. ACE Locksmith, who would have thought!? I hope this helps someone in the future that experiences this problem on these vans.
