Hi found that TSB that kinda refers to my problem.

Supercede:
This bulletin is being revised to add model years and additional information. Please discard Corporate Bulletin Number 99-08-52-005B (Section 08 - Body and Accessories).
The following information regarding Remote Keyless Entry (RKE) operation may be given to customers as needed.
The General Motors RKE systems operate on high frequency radio signals. Therefore they may be subject to radio signal interference which will affect RKE operation. Some of the typical conditions which result in reduced RKE transmitter operation are listed below.
To prevent battery drain, RKE transmitter will lock up if any button or buttons are depressed longer than 30 seconds. The transmitter will unlock if another button is depressed. While programming the transmitter in the relearn mode, use the J 43241 tester,
to confirm that the signals are being transmitted to the RCDLR. If the RKE locks up during the programming, depress another button to unlock the RKE.
Note Always refer to SI for latest diagnostic information
Proximity to radio towers airports police and fire towers.
The presence of fluorescent lighting.
Installation of some aftermarket accessories have been known to affect the RKE performance as well.
Some brands of radar detectors CB radios walkie talkies mobile radios cell phone chargers and cell phones (especially 3-watt bag phones which are placed on the floor of the vehicle) have jammed the radio frequencies of the RKE system.
Remember these devices do not have to be in the customers vehicle. They may be in another vehicle which is in close proximity. However if the customer has one of these devices in their vehicle and if the RKE system works with these aftermarket devices unplugged refer the customer to the aftermarket supplier. The aftermarket device may not meet the requirements of the FCC Code.
If the customer comments that the remote transmitter fails to operate press each button on the transmitter one at a time while observing the vehicle systems.
If only the fuel door (Cadillac) or panic button (all other vehicles) works or the transmitter fails to operated re-synchronize the system following the transmitter synchronization procedure found in the Keyless Entry sub-section of Body & Accessories in the Service Manual.
This happend with my #1 key fob. But all tries to reprogramm / relearn this keyfob were without success. The lock / unlock buttons never reacted. Its probably more a problem of the circuit IN the key fob.
If the RKE system is auto-synchronized reprogram the transmitter following the procedures in the Keyless Entry sub-section of SI.
DO NOT REPLACE ANY COMPONENTS.
Re-synchronization must be performed if the following conditions exist:
The batteries of the keyless entry transmitter have been replaced. A keyless entry transmitter is malfunctioning.
If all of the transmitter buttons fail to function check the battery and transmitter using tester J 43241. Refer to Corporate Bulletin Number 83-90-12.
If the transmitter passes the test program the RKE system following the procedures in the Keyless Entry sub-section of Body & Accessories in the Service Manual.
Remember when programming the system, all transmitters for the vehicle must be present for the programming to be successful.
On many 2006 vehicle lines RKE transmitter commands can be viewed using a scan tool (under RCDLR Data Displays).
If the transmitter fails the test with the tester J 43241 replace the batteries and retest the transmitter using the tester J 43241. If the transmitter still fails the test replace the transmitter.
------------------------------
I talked to a German shop that permanently deactivates the passlock / theft deterent system in Aleros and he told me that it could only be done permanently.
He mentioned another Car type were sliding doors could be programmed to the keyfob using the US RCDLR --- WHAT THE HECK IS RCDLR ????
Here is a wiring diagram I found, but I kinda get the feeling that is not all there is to this system. Where is the receiver for the keyfob?
This is starting to get pretty annyoing. There has to be a way that I can drive my car even if the keyfob fails
