I was looking at getting a new steering column . I currently have a vats system the new column has passkey which I belive is older version. Is this compatible?

 

VATS is Passkey, they are two different names for the same thing.

thank you ,next question is if I get a different column with a different resistance how do I resolve that.

 

You have to have the matching passkey module for the resistance of the key or swap out key cylinder with old cylinder

 

okay so I just bought a new column with a new passkey module and key. What do I have to do to make that work with my current system thanks I couldn't find these exact answers anywhere else

 

Use the matching module and tear apart half the dash or use your old key cylinder and old key.

 

so if I replace the old module with the new one and just plug it in everything will work as it should.. I probably will wind up doing that considering I need to do heat core anyway. Thank you

 

Technically for GM, "VATS" stands for: "Vehicle Anti-Theft System".

GM has Two Sub-Systems of VATS:
-1: Pass-Key (Found in our Cars), Pass-Key II, and Pass-Key III (Until recently Modern GM Vehicles would have either "PK3" or "+" on the Key for this System.
-2: Pass-Lock (another System with multiple revisions, and the Key is NOT part of the System, just the Lock-Cylinder is).
