control unit anti theft alarm end lock anlock system

[IGOR.N]

Is there anyone who can help me solve the problem with the central remote locking. I also replaced the motor on the front left door and nothing changed. The problem is this: when I lock with the remote, it unlocks immediately with the key, when I lock, all the doors lock. Chevrolet Aveo 1.4 96kw 2009

Not sure that I fully comprehend what the situation is?
On US based GM products, you can use the KEY-FOB, to lock or unlock the vehicle.
Most US GM cars have only one key lock on the driver's side (Left) door, which will lock all 4 doors, simultaneously.
This occurs when the key is inserted, and the key is turned to the right.
Additionally, one can also hold the interior lock/unlock button/switch, on the door arm rest for 5 seconds, which will also lock all 4 doors, again simultaneously.
I would need more explanation, for further insight.

It is true that on the driver's side there is one lock that locks and unlocks all the doors and that is fine, the problem is that when I use the remote to lock or unlock it then it does that, locks and immediately unlocks just like when the driver's side door is open. I will try to make a video to better see the problem.

I will assume that the Key-Fob is the Chevy assigned one for your Vehicle.
The issue sounds like a BCM (body control module) problem.
The locks and the security system are routed thru and controlled by the BCM.
I had a similar situation on a 2000 Venture, after driving thru High Water, on Vacation.

The Venture would lock and unlock the doors, as one drove about, in a random fashion.
I purchased a new BCM, installed it, and the vehicle returned to normal.

First of all, I would like to thank you for the information. It seems that these vehicles have an electrical problem. I searched for similar problems to mine and found many people complaining about similar things.BCM (body control module) Can I know what it looks like and where it is located? I hope I can find it to buy or repair the old one.
Тhank you

The BCM is located underneath the dashboard on the left side (driver's), mostly behind the instrument panel fuse block,
near the steering column. You will need to remove the cover under the steering wheel( My 2006 Aveo LS just has snap-in fittings)
for access to the steering column area. The GM part #96650722 is now discontinued. The module will need to be purchased used.
After install the unit will need to be programmed at the Chevy dealership.
