Acura TL door lock/unlock on 2005 Acura TL

I have an Acura TL 2005. I can unlock the doors and the trunk using either the remote or manually pressing the unlock button inside the car. However, I can't lock the doors and the trunk with either the remote or manually pressing the lock button inside the car. Any ideas?

I have the same problem on my 2004 tl. Have you found a fix?
Unfortunately...no...i did take it in and the mechanic thought it has something to do with the door actuator. they estimated that it cost about $350 to fix it. so i opted not to have it fixed.
Its prob the actuator. That piece thats known for going out. You can manually lock them but it doesn't respond with the remote.
On mine if my door is unlocked it wont lock with the remote. If its locked it wont unlock with the remote
