SOURCE: sliding doors won't lock or unlock using keyless.

there are 3 possibilities that I would check first. 1: make sure the contacts on the door, and body where the touch are clean. the lock and unlock signal are sent through these. 2: You may try replacing the battery in your key fob. 3: the power lock motors may have gone bad. To check, lock the doors with the drivers door panel, if they lock, they are fine. Another solution may be to recode your key fob. procedure for coding the fob to your vehicle can be found online.

You have a intermittent condition. To isolate the cause: 1.Disconnect the drivers door lock/unlock switch from the connector. Drive the vehicle and see if your random lock/unlock condition has stopped. If it has, replace the switch. If it hasn't:
2. You have a grounding problem or a problem in the BCM (Body Control Module) and should have a technician use a Tech 2 Diagnostic Link Tool to access the BCM computer to obtain any fault code data to help correct the condition.

SOURCE: key fob will not activate anything. can't

I too had this problem. I finally found out that my problem was the result of the metal contacts that touch the circuit board when you push the buttons had worn out. To correct my problem, I purchased a small pad that slides right inside the remote and fixes all the buttons. Since then, my remote has worked problem free for the past 3 months. The company that makes the pads is KEYLESSFIX. The following link will take you to the actual website:

My Buick 2004 rendevous,my door ajar light stays on and it dings, and the locks, lock and unlock a the while when driving


Probably the switch input to the BCM is bad . door ajar switch .
The BCM is also capable of commanding other vehicle systems to control functions that are not directly wired to and/or controlled by the BCM. The BCM accomplishes this task by sending specific messages on the class 2 serial data link. The vehicle system capable of performing such function will respond to the BCM message.
The BCM controls/monitors the following functions:
• Audible warnings
• Indicators control
• Interior lighting
• Exterior lighting
• Power/automatic door locks
• Keyless entry
• Content theft deterrent
• Personalization
• Serial Power Modes
• Electrical Power Management

Audible Warning
The body control module (BCM) provides the following audible control functions. Some audible control functions may be controlled by other systems through the class 2 serial data link:
• Headlamp on reminder
• Key in ignition reminder
• Personalization mode
• Delay locking indication
• Keyless entry programming/diagnostic mode indication

Indicator Control
The body control module (BCM) provides the following indicator control functions through the class 2 serial data circuits. Some indicator control functions may be controlled by other systems through the class 2 serial data link:
• Door ajar
• Liftglass/endgate ajar
• Park brake
• High beam
• Park lamp malfunction
• Service vehicle soon
• Personalization mode
• Security LED
• Battery

2007 dodge grand caravan sliding door opens by itself when unlocked and unattended. The door unlocks and opens itself. Will not do it when locked.


The sliding doors are controlled by the BCM - body control module . The BCM is seeing an input from a bad switch of some kind thinking the door open request has happened . You best bet ,take it to a qualified repair shop that has the diagnostic testing tools .

Watch these three videos ,check out the diagnostic tool this guy uses.

I have a 2006 GMC Envoy Denali. The power locks on both the rear passenger side wont unlock automatically. i have to manually unlock it. although the automatic lock option works. All the other doors work...


both the rear passenger side wont unlock ???? How many doors are on the passenger side ? Or both back doors don't unlock ? Two relays lock / unlock the back door's Not the lift gate . The BCM controls the relay's . The relay's are located in the rear fuse box . Under back seat .
