Question about Chevrolet Cavalier
If you know for sure that the transmitters are transmitting (tested on a key fob tester), and the remotes are the correct ones for your vehicle (haven't been recently replaced with a different part number), then you may need to simply re-synchronize your transmitters to the vehicle. This is different than reprogramming the transmitters, but uses the same method on the remotes.
To resynchronize, Stand within 5 feet of the car, with the remotes. Press and hold the LOCK and UNLOCK buttons on the REMOTE for about 7-10 seconds. If the transmitter was out of sync with the car, the horn will chirp to confirm it is now synchronized. If this method does not work, then the transmitters will have to be programmed to the vehicle, which requires a scan tool to do. Good luck :)

10 year old remotes go bad often, especially due to moisture retention.

Testimonial: "Thank you, yes both(2) remotes are bad. I found a testing machine at a local auto parts store, even with new batteries the remotes do not send signal."
The remote doesn't work but the lock actuators are in question as some of the locks work pushing the buttons then the ones that don't work can start to check by disconnecting the wires that work the bad ones and then see if the remote will work with the bad ones turned off. replace the bad ones then your ready to go after the remote. With your scanner connected to the vehical ( not a code reader ) put the unit in body mode and look for codes and test for the door lock system follow directions and don't skip any steps. If you don't have these tools and the experience using them hire a shop that does. Expensive mistakes can be made in the ( scanner ) world of repair and your not likly to be wealthy enought to find out. Your local auto parts store can find you a good mechanic that works in his area that they sell parts to. and they know who the good guys are.

Just figured it out and replicated it 3 times..
any type of power/voltage change seems to trigger this issue
The most common symptom is power locks fail and only the driver window quits, however that is on the extended cab.
Steps to fix and it works every time.
take door panel off driver's door
Disconnect the wiring attached to window and power lock control unit
disconnect battery cables
connect the negative to the positive cable(((NO BATTERY CONNECTED)))
This will act to short residual voltage in the system
5 minutes later
place the key in the ignition and turn to the run position
connect the wiring to the window/lock controller
connect the negative cable to the battery
then the positive
open drivers side door
turn key to the off position((do not remove yet)) you should get a series of dings through speakers telling you the key is still in the ignition
once it begins dinging pull the key out and you should hear the door lock solenoids trigger and the windows should work.
Three years and a very unhappy girlfriend who owns the truck. but she's happy now.
