Okay. I have done some research (my head is killing me). I'm with you when it comes to computers, modules.
There are two things that can be causing this. One is a GEM relay (generic electronic module) which runs the locks, or a bad relay. Based on the several pages I read, I think you simply have a bad relay.
Locate auxiliary relay box #2, above the left rear wheel well and remove the lock relay. You need to check resistance between terminals 30 and 87A. If the resistance is more than 5 ohms, replace the relay. If not, apply battery voltage to terminal 86 and ground 85. Now read the resistance between number 87 and 30. If the resiistance is more than 5 ohms, replace the relay. If all tests are passed, we need to move on to the GEM.
Here is a picture of the relay to help you identify pin numbers. Let me know if this helps.
