Buick LaCrosse CXS my trunk opens when I dont want it to.

Customer Question

my trunk opens when I don't want it to. Probably from the remote in my pocket hitting something. Can I disable this feature? All I need is to be able to open the trunk by touching the rubber button at the trunk lid. I don't need the remote open, and I often keep valuables in the trunk. When I come back to the car, the trunk lid has been open many times, and it is a high security risk.

Can I disable this feature?

 

Vehicle lock/unlock functions and remote vehicle start remote vehicle start settings may be personalized, but it is listed in Owners Manual & I do not have a copy
Or Dealer may be able to Program out the function

 

OR

 

At the BCM find the YELLOW wire located in the PINK 27-PIN PLUG, PIN 15
Cutting this wire should disable the Remote Function.

The BCM is what? and where is it? Can I just disconnect a wire somehow (or pull Pin 15 from the plug) instead of cutting it?

The BCM is what?

 

BCM = Body Control Module

 

and where is it?

 

Located under Driver Dash on Left, see image below

You need a Special Tool to remove the PIN, & then trying to reinstall it, it can break. Plus you would have to disconnect the Plug.

If you cut, it can be quickly spliced together.

Thanks for the help. One more follow-on. If I cut this wire to disable the remote function, is this just the trunk (release) remote, or will it also disable any other remote function?

Should be only Function as this is the Trunk Activation wire from the BCM
