Trunk problem

[1olddude]

Three buttons on mine, one for the door lock, one for the trunk, and one for the frunk. I can't figure this one out. Close the trunk, drive a few miles, trunk pops open and the dash light comes on. I am going to try my other key when this damn snowstorm gets out of here. Thanks for all the advise. It doesn't sound as if anyone has really had this problem so I guess I am a pioneer. I will keep you posted. I am assuming when you replace the battery in a key, then you have to go to the stealership and have it reprogrammed? I wonder if my key battery is getting weak. Oh well, I will stop speculating and get to figuring this one out. Winter just won't let go here quite yet.
