The door locks should work even without the factory (keyless) radio. If the under hood fuse #51 is good testing the door lock control unit in the drivers door would be the next place to look.

 

What does the door lock control unit look like? I have a power probe 3. What is the best way to test it?

 

it is a little blue box inside the door panel.

 

These should get you started.

 

Awesome. Thank you for the illustrations.

 

Is there a way I can check the control module itself using a power probe? I will go through the wiring as well. I guess it is common to only have one unlock button on the driver's side. How much does it cost to get the OEM keyless entry system?

 

The third picture outlines testing the control modules wiring. The last part of it test the lock/unlock function. If those pass the module is bad.

The keyless entry is built into the factory radio. If your car/radio is keyless equipped you would need to get a factory key fob and program it.

 

Pull the main plug that goes into the driver side door (in the door jam). Big BIG problem with the LX models. Pull the rubber boot back and check those wires. My window works but the locks do not, I pulled that rubber boot back to find several wires pulled out and ripped in two.

 

Are we talking about the plug that goes into the module that has corrugated tubing around it or between the door and door jam? I am hoping to fix this over the weekend. I can intermittently get both of the drivers side doors to lock and unlock by shaking the wires but neither of the passenger side doors respond when I do this so I suspect shorting or broken wires. I just want to know how far back to look. Thanks for the help.

 

What 87REX mentioned is in between the the door and body. It's not limited to LX trims though.

With what you said about intermitant driver side operation and no passenger side I'd look in the boot between the body and door first.

Not my picture
