Unfortunately, there is not a proven way to permanently bypass the system but if your alarm is going off, the only way to disarm it using the lock is with the key. Here is a guide that talks about this:
However, what I would suggest is you have the locksmith, or another locksmith cut you a metal key that fits the doors. This does not have to have a chip or be an ignition key, only match the metal key from the original lock cylinder so that you can unlock the door and trigger the disarm switch.
Otherwise, you are going to have to apply the proper amount of voltage to the BCM so that it thinks you unlocked the doors.
The way this works is when you unlock the door using the key, there is a voltage signal sent through a resistor and when the BCM sees this reduced voltage it knows that you unlocked the door and shuts off the alarm.
The only issue with this is to know the size of the resistor we need to unlock the lock and measure the resistance through the switch. Clearly you need a key for this. I would suggest just getting a metal key cut to what lock is in the door and that should solve this issue.
