First thing first are you sure that your BCM box is bad what symptoms are you experiencing I had a similar problem just the other day I thought my BCM box was going bad my brake lights would come on and stay on and my cruise control would also not work do to my brake lights staying on I went on line to check this problem out and found out that this was an easy fix that my box might not be bad at all, if your having similar problems try this first go to your local parts store and buy you a tube of dielectric silicone compound unhook your ground cable on your battery go to your BCM box and remove the two big grey plugs once you have removed them open the tube of grease and put a finger full on your finger and rub it inside where the plugs go and spread it evenally as possible once done rehook your grey plugs and then replace your cover and then you can rehook your ground cable this is what i done to my car and it fixed my problem. hope this helps... Here also is the bulletin i went to just type in technical bulletin #08-05-009c and it will explain more about it.

SOURCE: Is it possible to program my keyless remote myself
Yup I agree with Mr.emissionwiz. I ran into the same problem a month ago. My remote entry got wet and had to buy one. Fortunately, I found them cheap on Ebay, but had to take the car to the dealership to get it programmed for about $50.

You might want to check the MAF Sensor it's located on your air intake tube. Or check the connections between the tube and the air box and make sure they are connected tight. If this isn't the problem then one of your O2 sensors have failed and you should take it to any mechanic that fixes cars. The dealer will rip you off. But this is an easy fix.

The ignition is in the ON position.

The vehicle is shifted out of PARK.
The BCM will then unlock the doors when the ignition is placed in the OFF position. Do the exterior lights flash as well as the horn sounding ?
Body Control Module (BCM)
The
Content Theft Deterrent
system is an internal function of the Body Control Module (BCM) which utilizes class 2 serial data and various switch input information to perform CTD functions. When the BCM detects an unauthorized entry, it activates the horns and exterior lamps.
When the BCM detects an unauthorized entry, the BCM enters the alarm mode. The BCM activates the horns and exterior lamps for 2 minutes. This is followed by a 3 minute time-out with the horn no longer active. If no new intrusions are detected after the time-out, the horn is not active. The system must be disarmed or the intrusion condition removed after the time-out for the system to exit alarm mode.
