I cannot lock the drivers door with the remote, but can lock/unlock all doors with the key. However, the alarm will not set by doing this and can only lock/unlock the other doors with the remote and activate the alarm.
We replaced the drivers door module, but still no luck.

Hello,

It sounds like the driver door lock driver is out in the security module. Here is a wiring diagrams and a guide to confirm the issue. Check for an output signal from the module.
