Front doors wont open - Security Feature?

Sorry Andrew , no BCM on this vehicle . The Central Security Module is incharge of power door locks . Central Security Module For additional information, refer to Section 419-10 .
The central security module is equipped with a battery back-up which holds the programmed transmitter(s) memory in the event of the vehicle battery disconnection.
Principles of Operations The Door Switch Lock Function When a door lock switch is moved into the lock position or a door lock cylinder is rotated to the lock position, the door lock switch grounds the lock circuit input to the central security module. The central security module then provides 12 volts to one side of the door lock actuators contained in the door latch unit and simultaneously grounds the other side of the door lock actuators. This completes the door lock actuator circuit, causing the door lock actuators to rotate a cam assembly, which then locks the doors.

The Door Switch Unlock Function When a door lock switch is moved into the unlock position, the door lock switch grounds the unlock circuit input to the central security module. The central security module then provides 12 volts to the opposite side (relative to locking the door) of the door lock actuator(s) contained in the door latch unit and simultaneously grounds the other side of the door lock actuator(s). This completes the door lock actuator circuit, causing the door lock actuator(s) to rotate a cam assembly in the opposite direction, which then unlocks the door(s). The 12 volts which the central security module provides to the door lock actuator(s) are provided to each door lock actuator from the individual pins on the central security module connector.

Keyless Entry When a remote transmitter button is depressed, it transmits the appropriate command to the central security module as a radio frequency. The central security module receives the command from the remote transmitter through an antenna, which is incorporated in the central security module.
When the central security module receives a command from the remote transmitter, it then sends the appropriate output to control the desired devices. These outputs devices include:

• The front and rear door lock units.
• Central timer module (CTM).
• The liftgate release motor.
• The right and left side turn signal lamp(s).

The central security module sends a signal to the CTM when courtesy lamp illumination is required.
Computer Operated Locks Each front door lock actuator contains a bipolar motor that controls the lock and unlock linkage. The lock/unlock lever of both front door interior handles use linkage to actuate the lever lock switch located inside each front door lock actuator. Each lever lock switch remains in the unlock position until lock/unlock lever of the interior door handle is moved to the lock position. This action toggles the lever lock switch to the lock position. The central security module uses only one electrical input for both lever lock switches. The central security module cannot determine whether the driver or passenger door lever lock switch was actuated. Therefore, actuating the lock feature from either front door will have the same affect of locking all doors. Actuating the unlock feature will not unlock any other door.
The door lock control switches for both front doors also use only one input to the central security module.
Both rear passenger doors contain a rear door lock actuator that controls only electric lock or unlock of the door. Actuating the lock/unlock lever at either rear passenger door will have no effect on other doors.
The panic feature of the remote transmitter sounds the vehicle horn when the vehicle is not equipped with anti-theft. If the vehicle is equipped with anti-theft feature, a separate horn is sounds for the panic feature.

What sort of 'interlock'? If it is anything to do with the security system or imobillizer, you can't do that. If it is the shifter interlock, you can't remove that safety feature either, also controlled by computerized systems, ECM, BCM.

tis a process so here goes..... Central Security Module (CSM) enable/disable mode allows autolock feature to be turned on or off. To enter enable/disable mode, close all doors. Ensure ignition switch is in LOCK position. Perform the following steps within 30 seconds:

Turn ignition switch from LOCK to RUN position.
Press power door lock switch UNLOCK button 3 times.
Turn ignition switch from RUN to OFF position.
Press power door lock switch UNLOCK button 3 times.
Turn ignition switch from LOCK to RUN position.

CSM module should chirp horn indicating CSM module is in enable/disable mode and ready to accept program changes.

Press power door lock switch UNLOCK button once to command CSM module to toggle autolock feature on or off. Press power door lock switch LOCK button once to enable/disable autolock feature. CSM module will chirp one time to indicate autolock has been disabled.

CSM module will chirp once, followed by a longer chirp to indicate autolock feature has been enabled. Press power door lock switch UNLOCK button once, then turn ignition switch to OFF position to exit enable/disable mode. CSM module should chirp once to verify a feature change. Best to you.

Do a reset on the door system, by pulling the door fuse. I don't have location, possibly drivers side fuse box.

Contact the dealer ,i think theri is some sort safety feature with a sensor at the front of the car or a fuel cut off switch under the bonnet in the engine compartment so contact the dealer to be sure as iam not sure here

When the light is on, the security feature of immobilizing car-wont allow starting-is active. Pretty difficult and time-consuming to permanently disable the security system, but some have figured it out and published their research over the internet. If yours gets worse, if the light stays on more frequently, you may want it permanently removed. I think it was a ruse by GM and car makers to add cost, and cause more frequent repair visits, but that just me.
Google "disable vehicle security system" or some such, to see results.

You either have a bad "arm/disarm" switch or the switch has fallen off from the lock cylinder.

What is happening is the security system is not receiving the disarm signal when you unlock the door with the key. It thinks the car is being stolen so it continues to lock the lock to prevent this.

There arm/disarm switch is clipped onto the door lock cylinders on the front doors and the rear hatch. If it does the same thing with the other doors than there may be an issue with the security system. If the other doors work fine than I would pull the door panel (I assume you are getting this problem with the drivers front door) and inspect the switch.

Here's a pic of what it looks like

If you have any questions let me know.

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

the only thing i could think of would be the child safety feature but that is usually only for the rear doors. i think she just panicked because the front doors are set up so that if you pull the door lever the lock pops up.

There is a security feature that will allow to go for a short distance but will stop. It is basically the same as the alarm, when you lock your doors, and then shut the door as you exit, there is a red security light that will blink in the dash. If you manually unlock and open any other door besides the driver door, the alarm will go off. To disable the alarm you have to cycle the key in the driver door. The same goes for the security feature. Cycling the key in the driver door lock manually, should disable the security feature until the doors are locked again. There may be a problem with the remote if you use it instead of you key to unlock your door.

The same thing happened to me last evening except there was a tremendous Rain storm.
When we returned the car was flooded inside!

Dealer said there was a TSB 09-2-1 on this problem.

When you insert your key into the door lock, turn and hold the front windows and the sun roof will open.. referred to as a " GLOBAL FEATURE"

To eliminate your problem this feature must be deactivated...
A computer module must be replaced which will change security code etc.
Not a cheap fix!!!!!
