if the instuctions say top use the keyfob buttons try a new battery in the fob. 13 years old is2 times normal life of that battery
and if weak, it can fail in very very odd ways.
the coin cell is a $1 fix. also told in the manual how.

Try replacing the FOB battery. Check the fuse for door locks. usually located in the engine bay fuse box. Temporarily you can lock the other doors from inside the van and lock the driver door last using the key. Another possibility is that the locking switch in the driver door is faulty or the central locking motor is. All other doors will only lock if the driver door locking system works. When you lock the driver door, the locking motor will hit a switch that will lock the other doors.

Ignition Lock Cylinder Control Actuator
If the vehicle is equipped with a floor mounted console gear shifter, it has a ignition lock cylinder control actuator system in the steering column as an added safety feature. The ignition lock cylinder control actuators purpose is to prevent the steering wheel from being locked when the transmission is in gear and the vehicle may still be moving. The column ignition lock system consists of a ignition lock cylinder control acutator, and a park position switch that is located in the A/T shift lock control switch. The ignition lock cylinder control acutator contains a pin that is spring loaded out to mechanically prevent the ignition key cylinder from being turned to the lock position when vehicle transmission is not in the Park position. If vehicle power is lost, and/or the transmission is not in the Park position the operator will not be able to turn the ignition key to the lock position and will not be able to remove the ignition key from the column. GM has had some problems with this , If you have the console shifter there is a micro switch that when put into park a linkage pushes on this micro switch closing the circuit to ignition lock cylinder control actuator allowing you to remove your key ! These linkages fall out causing this problem ,an have electrical wiring problems as well ! I fixed a 2006 Chevy cobalt that had this same problem by getting a used shifter assembly at the auto salvage year ! cost $20.00 . There mite be a access hole under the bottom of the steering column with a release button up inside !

Lock/unlock motor may be failing. Remove the door panel and remove the connector from the lock motor. Check the dc voltage at the connector while pressing the lock switch. If you see battery voltage, replace the motor. If the voltage is low, inspect the wiring.

Electronic Park Lock (EPL)/Ignition Lock Cylinder Control Actuator: If the vehicle is equipped with automatic transmission and a floor mounted console gear shift, it has an ignition lock cylinder control actuator system in the steering column. The ignition lock cylinder control actuator purpose is to prevent the ignition key from being turned to the OFF position when the transmission is in any position other than PARK and the vehicle may still be moving. The column ignition lock system consists of an ignition lock cylinder control actuator, and a park position switch that is located in the automatic transmission shift lock control switch. The ignition lock cylinder control actuator contains a pin that is spring loaded to mechanically prevent the ignition key cylinder from being turned to the lock position when the vehicle transmission is not in the PARK position. If vehicle power is lost, and/or the transmission is not in the PARK position the operator will not be able to turn the ignition key to the lock position and will not be able to remove the ignition key from the column.

Does your impala have floor shifter ?

This Van has a system in it called delayed exit, this means the radio and other accessories stay on for a time as long as none of the doors are opened, when the door is opened the module senses that switch in the door is activated and shuts everything off. The easy way to test this is open the passenger door, if all shuts off you found the problem, the driver door switch is defective. the switch is attached to the door lock inside the door.
