I have a 01 5.3 vortec in my third gen I thought I could put a vats bypass module but peaople are telling me it's not pass key it's passlock do they make a bypass module for 5.3 vortec? If so does anyone have a link for it?

 

Plain and simple rule is, if the donor PCM is from a car with a chip in the key, a module can be used. If the donor PCM is from a vehicle without a pellet chip in the key, it must be tuned out of the PCM, no module can be wired in.

Passkey- pellet chip in key
Pass lock- no pellet in key.

Any of the 99-up GM trucks or SUVs are a pass lock security system. You have to have the PCM tuned to get rid of vats, a module won't work for your situation.

 

I was looking on eBay there's a few passlock modules on there?

 

The way I understand it, the trucks use transponders to communicate and enable/disable vats. Even with a bypass, a thirdgen doesn't have all of the nessasary parts to make the system function.

It is plain and simple as sending the PCM out and having vats deleted.

That or buy a LS1 PCM and then wire in a bypass module.

Or have your PCM reflagged with a ls1 tune and then wire in a bypass module.

Neither of these are cost effective solutions to just having your PCM you already have sent out to have vats removed.
