2003 Buick Regal Starts W/O KEY

[ohjunk68]

I have a 2003 Buick Regal that wouldn't crank because of the vats security issue. I replaced the lock cylinder & ignition wiring harness. I then did the resistor bypass and now it starts & runs. My issue is the lock cylinder never locks. The car can be started without a key. Is this because of the resistor bypass. I don't want to be looking for additional problems if they're not there. I'd appreciate anyone's help.

No….you have a mechanical issue. Go back in there and check your work.

You used a new lock cylinder?

No mechanical issue. I've researched YouTube & a lot of forums and found nothing about the problem. The car is running and I've got a new key w/ the correct resistance ordered... so I don't want to start looking for something that's not a problem.

Well something is wrong with the lock cylinder. Either defective or not installed correctly.

If you bypassed the key resistor reader with the correct resistors matched to the original key, why did you order a new resistor key? 😕

Sounds like lock cylinder behaves electrically different/wrong.
There's power from ignition when it shouldn't.
Whats the issue with original lock cylinder?
