Keyless (KESSY) touch sensor, Door Handle Replacement

[El Serch]

Question, any one know has replaced the kessy on your car?
The Jetta I just brought, don't have the touch sensors, the previous owner changed the doors without the handle sensor.

Where I can get instructions on how to replace the handle?

here is the VCDS reading:

So if both doors were changed. Then the key would not work in the doors...

It looks like just the passenger side door was replaced. Which means it was in an accident. Look around an evil Bay I'm sure you can find kessy door handles. I've been meaning to replace my rear door handles with kessy ones.
