My 1994 Vanden Plas did the same thing. This sounds like the lock actuators are fried. They are not hard to put on but it is tedious. You can get after market replacements for about $5.00 "auto parts warehouse" and "jc whitney" but I went to the junkyard and harvested some from there.
I think you have to push the 'unlock' button twice in order to unlock the doors.
Then you have to lock and unlock the doors by hand.
They tend to do this if a door is not closed all the way. Check all doors. I have had this happen when my side door or rear hatch was not not closed all the way. Just open and close the doors. If it still continues, check the sensors on the doors.

Disconnected linkages, probably from trying to unlock with a slimjim
something that locks doors
On my 1992 190E I can lock the trunk with any of the keyed locks. If you lock the doors, the trunk locks and if you lock the trunk, the doors lock. In other words all the keyed locks are electrically interconnected. In reality the locks are not electrically interconnected. There is a pump in the right side wheel well of the trunk, it uses vacuum to lock all the locks and pressure to unlock them. Although the pump is powered electrically, the locks are not.
Scenic fuel cap locks operate with the door system - it's a security thing - if you use the remote to unlock your doors then you will find the fuel flap will open. Of course it will lock when you use the remote to lock the doors.
If the Avalanche is anything like a 2003 Chevy Silverado, you can program the door locks as follows: 1. With vehicle off, Pull back the High Beam headlight lever (High Beams are on) 2. Turn ignition key on and off twice (ON, OFF, ON, OFF) , then release the headlight lever. Your vehicle should respond my locking or unlocking the doors. 3. You can now PROGRAM your locks by pressing a three button code, using the unlock/lock buttons on your driver door. Your manual should have details of the buttons you should press. For example, Press Lock, Unlock, Unlock, - and your code will tell your when to unlock, or to unlock at all. Here are some of the possible Combinations (A and B) A - Do not Lock Doors Lock All doors When Vehicle Is Started Lock All doors When Vehicle is placed in DRIVE Lock All doors when Vehicle reaches speed of 5mph. + B Do not unlock doors Unlock Drivers side door only - when placed in park Unlock all doors - when placed in park Unlock Drivers side door only - when key is removed from ignition Unlock All doors- when key is removed from ignition. These are a few examples, that can be programmed by pressing the unlock/lock buttons (three times).. If you don't have your manual, then you can try random combinations. Once you enter your 3 button combination, the vehicle exits programming mode. You can now start the vehicle and test the locks. Or: Repeat the process.
In my church, the head usher locks the doors after the service.
I am having the same problem. It's as if the locks are frozen but it's summer.
