I used a cutoff disc on my dremel and attacked the existing door insert one night in the garage. I essentially had to cut almost the entire way around to get it free, but after about an hour of very careful cutting I had the insert off. I checked the mechanism on the inside of the door handle and the cable was still attached so it wasn't that. I honestly couldn't see a way into the other part of the mechanism other than removing the plate at the bottom of the door (which also has 4 bolts that hold the carriage for the window mechanism). In typical rookie fashion I managed to unbolt all of the bolts (yes including those for the window mech) but without having taped the window up. The window drops to the bottom of the door and took 45 min of fiddling with to get it re-seated. What's worse is that I couldn't get to the door mechanism. So, I swallowed my pride and took it in to the dealer. They were great about it and it cost me $100 for them to get the door open/working again (and the window properly seated). Turns out it wasn't the lock that wasn't functioning, but that the mechanism for the door opening was the problem. I was told it was all gummed up and just required a good cleaning to get working again. So, instead of the estimated $1300 with parts and labor it cost me just a hair over $200. Here's hoping in another 3 years it doesn't happen all over again.
man what a nightmare. i wish you the best of luck, and thank you for posting up a follow-up on here for everyone else to read. this is a common problem with all cars where links are involved.
-you want to hear even worse stories - visit the Audi or Mercedes or VW dealers. Those manufacturers use vacuum pumps instead of links to use as door lock actuators.
