Thanks for visiting Just Answer
There is a way to reset the security.
This process takes 30 minutes.
First, turn the key to the "crank" position. (either let the vehicle stall or not start)
leave the vehicle in the "run" or "on" position for 10 minutes. (Time it. Needs to be 10 minutes)
After 10 minutes turn the key to the off position.
Repeat these steps 3 times or 30 minutes.
At the 4th crank the engine will start if done right.

will this process stop the passlock system from engaging, after 10 minutes

it resets anyhow, its just a pain in the butt to have to wait.

No this will not disable the system but relearn the system with the key
