VW Electrics Changing Ignition Barrel
This how-to was posted by neil3965 and is replicated here for reference.
I lost my van keys. The only ones I had. Had been meaning to make some copies, but there you go.
I checked the code on the cab door handle - 8899 [not the real code, folks, but it's important for the end of this story!] and ordered a new key from eBay. It didn't work. Oh well, I thought, it's because the old lock is so worn.
Luckily, had a spare set of locks (also obtained from eBay) so decided to replace the old ignition lock. I wasn't sure if this was possible without removing the steering wheel and pulling off the steering lock (no key, remember), but it turns out that it is possible, and quite straightforward.
All you have to do is remove the plastic cowling around the the steering column (two screws, and a push clip). Bottom part comes off easily, smaller top part is more of a 3D puzzle but it does come off after a bit of Krypton Factorish twisting and rotating.
To remove the old barrel, you need to drill a 3mm hole in the steering lock casing at a point defined in the Bentley manual (saw no mention of this in the Haynes):
Easiest to use a caliper and scribe (tape or ruler and pencil would work too). First, scribe a line 12mm down from top edge of casing:
