I've read (and i'm currently in the process of confirming) that you can get new (90's) Sentra lock cylinders and swap the internals into your door locks. Buy em from like Oreilly, or Nissanpartsdeal or whatever. The set cost me like $23 or something for the doors. Of course, you'll either need to repin them, or use different keys for your doors and your ignition/hatch.Where can I find replacement outside door locks? I've been searching to no avail, well with exception of a few very high priced dealers. I don't want to pay the dealership.
