Durametric has 2 versions. The Enthusiast version will support up to 3 VINs. The Professional version is meant for mechanics and will supports an unlimited number of cars. There are people on eBay that rent the Professional Durametric for a reasonable price.

Can you explain the issue more? Is it locking and immediately unlocking? When does it do this (inner lock button, fob, key in door)?

The microswitches in the inner and outer door pulls (handles) only tell the window to drop a bit for when you open the door. It is the latch assemblies that tell it to keep the window down, etc. It also has the lock mechanism. If I were you, I would do the testing like the iceman suggested starting with the driver's side door latch.

BTW, from time to time my car almost seems to get out of sync. Going inside the car, shutting the doors and using the internal lock/unlock button a few times (until the light is off) seems to get things back in sync. Can't hurt to try.
