2000 Buick: 000 miles..flashed..my other key fob, and it..same thing…

Customer Question
I have a 2000 Buick...
I have a 2000 Buick Custom with 120,000 miles, give or take...anywho. I came out to my car the other day and pushed the unlock button on my key fob and noticed it didnt unlock but still flashed the lights. I just shrugged it off and tried my other key fob, and it to did the same thing. Frustrated I just used the key itself to unlock each door and went home, though I did notice not even the lock buttons in the car worked, and in the Driver Information Center it gave warning "Unknown Driver". When i got home, I checked all fuses, relays(that where in the fuse boxes), tried resynchronizing key fobs, 30 minute relearn technique, and even tried having the battery disconnected for 30 minutes. I'm frustrated because I don't know what else I can do short of taking it to the dealership and hook it up to a Tech1 Scanner and run diagnostics. I know the key fob works because I can open my trunk, and arm/disarm and set off the alarm if i choose to. Also strangely the key still starts the car. Any help would be amazzzingly helpful. Thanks for yalls time,
Josh

Hello & Welcome to JA.

John :

To diagnose your vehicle will take the use of a Tech 2 or similar too .The remote keyless entry syatem on your vehicle is routed through several modules in the vehicle.
Here is a starting point :
With scan tool installed try to communicate with the

Dash Integeration module
Drivers Door Module
Rear Integration Module
Remote Funstion Actuator Module

Communication with all these modules must be good .
Check diagnostic trouble codes for each module.
Any code displayed with "U" is a communication code.
Test output function of each module.
