Keyless Entry
I have a 02 screw lariat and I can not figure out what problem I have with the keyless entry.
None of my remotes work. Ive tried replacing the batteries, made sure its in the correct way, and tried to reprogram them.
I can get the truck to go into programming mode (8 on/off cycles) but when I press the button on the remote, nothing happens.
All the lock/ unlock buttons work fine, including the exterior keypad. All the interior electronics (radio, windows, lights, etc.) work too.
Could I have a problem with the receiver under the dash, or am I doing something wrong?

Makes me think it's an antenna or feed line problem...

I have a little device I bought to check remotes.... but they also have a thing at my Autozone that you can take your remote and see if it has output signal. I'd check the remotes first.

This seems to fit your situation.
If the system does not go to mode after the initial procedure, I'd check the fuses. I know it sounds silly, but that was the problem with my lil Red truck. I couldn't get mine to go there either. Then I checked the brake lights and found that they weren't working. Underhood as well as the dash fuses.
Also make sure your brake light switch wires aren't broken. This is a fairly common problem. The switch moves with the brake being depressed, so the wires can break, come loose, or just not make a good contact. Any of this can cause a no read situation with the PCM.
