Ok, I lost the torx bolt that isn't supposed to be able to come out. I'll spare you the story, but the fact is, it's gone. Where can I buy a replacement? I've googled everything I can think of and the lock of my Versa on the driver's side is being held on by a piece of duct tape (cut very precisely I might add). If anyone has any insight on where to get a new torx bolt, I'd appreciate it.

Lost inside the door? Or just lost forever?

If it fell into the door you can get it back, you just have to take the door panel off. I'm new to this forum, but I'm sure you can find a "how to" to take the door panel off. I have done it on my 2007, but the WRONG way and ripped out two bolts. But you will get access to inside the door.

You will probably have to go to the dealership to order a new bolt or they can get it out of the door if you don't feel comfortable taking the door panel off.

Good luck
