It locks fine with the key fob, but I need to use the actual key to unlock the drivers door, i can then push the ulock button as normal on the inside door to unlock all the others. I have 2 key fobs and they boh have the same problem. The Chevy is a 2003 model. What could cause this and how do I fix it?

Not sure if lock has solenoid or electric motor, but either way, can you hear clicks or any prominent sounds from the door whilst trying to unlock it? you may need to put your ear on the door, if no sound, then wiring needs to be checked, then motor or solenoid, if you do hear similar sounds to the other door then the mechanical part of the lock mechanism has failed and may require a kit or replacement.
if the key does not turn the lock spray it out with wd 40 run key in and out of lock few times.because everyone uses remotes to open their cars the waffers in the door locks get coroded and wont fall in proper place when key is inserted.give it good cleaning and see if it will unlock
Walk out to the vehicle with a new battery in the key fob and press the lock AND unlock button at the same time while you stand close to the vehicle for 7 seconds. You will hear the doors go thru a lock and unlock cycle, your fob is now programmed. This will sync existing programmed controllers, security sync. to program new remotes:In the trunk, connected to the wireless remote controller (driver side on wheel well, need to remove 'mat') is an empty connector with 2 wires connected. short the two connector pins. The locks will all cycle. Press and hold lock/unlock buttons on remote until locks cycle on/off. repeat for other remotes. Remove short across connector pins. Test new remote(s).Warning:existing remotes are deprogrammed, only remotes programmed will work from now on.This worked on my 1998 Cavalier. Be sure battries in new remote(s) are good! Answer Locate the data link connector under the dash (under the steering column). Ground out pin #8 of the DLC (top right port) with a jumper wire to any piece of metal close by (I use the e brake hardware). The door locks will then lock & unlock to let you know you are in the programming mode. Simultaneously press & hold the lock & unlock button on one of the keyless entries until the locks cycle (this lets you know the transmitter has been programmed). Repeat this step for your second transmitter. You must reprogram the 2nd transmitter within 60 seconds of programming the 1st one or you have to start over. Note
with doors closed. hold down unlock button on drivers door cut key on and off two times you should hear locks cycle and horn chirp. release unlock now program fob by holding both lock and unlock. you will have to program all fobs. cut key on to exit programming mode
Instructions to program a keyless entry remote for a Chevy Silverado. They also work on 2003, 2004 and 2006 Suburbans.

Your book should give you program options for the door locks If your fob wont work either you got a relay for the door lock bad it is located in the fuse panel push the door lock button and find the one that is clicking
there are 3 possibilities that I would check first. 1: make sure the contacts on the door, and body where the touch are clean. the lock and unlock signal are sent through these. 2: You may try replacing the battery in your key fob. 3: the power lock motors may have gone bad. To check, lock the doors with the drivers door panel, if they lock, they are fine. Another solution may be to recode your key fob. procedure for coding the fob to your vehicle can be found online.
