Fob doesn't work on driver's door.

You need to visit an auto electrician, an alarm installer or an auto locksmith. The key fob needs re-pairing to the locking system.

Git the fob workn. Vehicle battery may be old or electrical system may not b charging the modules. Car shud be scand

Could be your driver door lock mechanism that is going bad , since the other door are working, it cannot be the fob. I would try to change the driver side door latch mechanism.

try the other fob.
the buttons on fobs can short.(its just a plastic membrane with carbon pad in the fob and can go bad.(cracks or crumbles inside...........)
so put the suspected fob far away from car, and use the good new fob. work now, and a new FOB battery, too.
if you only have one fob, now's the time to get the spare.
no fob lasts forever. not not ever.

Usually when you change a Fob battery you have to re-sync it to the car. Some cars have you lock and unlock the drivers door with the key.
Should be in your owner's manual.

you may need to replace the door locking actuator, they do tend to go bad over times. does the driver side door lock automatic when using the lock button on the driver side. if you can lock and unlock the driver side door with a switch, my guess would not be the locking actuator, it might be in the remote locking module.

more than likely the lock solenoid in the driver side door is not working. it located near the latch inside the door.

To get inside the car .... Use the key in the lock cylinder, unlock the drivers door to get inside. You shouldn't have to reprogram the fob unless it or the keyless module was changed. There may be a blown fuse that supplies the keyless control module (check the owners manual for location). or wires that lead into the Drivers door may be damaged ... The keyless module is located inside the drivers door at the bottom behind the door panel ... do the unlock/lock and trunk release switches on the inside of the drivers door operate the locks and or trunk release? If so it is not the fuse ... and not the wires to it ... And it could be your BCM body control module, located in the dash board to right of your gas petal. Because the number entry keypad (code for that is on the inside of the right passenger trunk bracket arm) also doesn't work I assume it's not the key fobs themselves. Your 98 manual is correct for your car.

Here's what I suspect is happening. The door locks will lock and unlock normally when the key is OUT of the ignition. If the key is IN the ignition, the doors cannot be locked (manually, key fob, or otherwise, if the system is operating as designed - prevents the doors being locked when the key is in the ignition). I've seen this problem before, but on a Santa Fe, not an Accent. The ground signal of the right hand front passenger door was lost, and the doors automatically locked. Perhaps something similar is happening in the circuit between the ETACS module and the right front passenger door lock/unlock actuator. Could be anywhere in the circuit.




These wiring diagrams may be helpful. The relays expecially may help solve this issue. As you can see, these relays are also controled by the ETACS module (Remote Keyless Entry).

The driver's side door lock button is designed not to lock from the inside unless the handle is pulled, or the power switch is used. This serves as a reminder to not lock your keys inside.

If you are inside, and push down on the button (not the switch) hard enough to lock it, you've probably damaged it.
