Default Why did the spoiler go up? Kinda long.

Last night, as we were leaving for dinner, I noticed in the rearview mirror that the garage door next to the Porsche's was up. Came back to the house and my wife got out to close the door. (Her BMW X5 occupies that slot.) While she was out of the car I press the button to open the Porsche's garage door so she could exit the garage, but somehow the Porsche's Homelink was now operating both doors! We got both doors sychronized down and went to dinner. When we returned home the cars Homelink once again opened both garage doors. We tried a few things such as unplugging one doors opener for a few cycles but both doors were still being operated with the Porsche's remote. Her BMW still just operates it's door.

So after a few minutes we decide to figure it out in the morning and go in the house. This morning I go into the garage and I noticed the 997's spoiler is up??? I open the door to lower it and I noticed the door window glass does not drop. Of course I left the key on the night before and the battery is probably completely drained.

Presently I've got the CTEK plugged into the car. If that doesn't charge it I'll use the big charger, get the car started and go for a long drive, and hope the battery is still OK. If not, the battery is 4 1/2 years old so it's probably getting close to replacement time anyway.

So my questions are:
Why is the Porsche's Homelink operating a garage door it was never programmed for? and

Why did the spoiler go up?

The spoiler going up on its own is due to heat in the engine area. Was the car driven that day? If not, then you are having a computer issue with the car. When these things are losing power from their batteries, all sorts of odd things happen to their systems. If you get the battery back up to where it belongs and it appears to have fully recovered, it's probably going to do everything normally again. Low battery voltages lead to a lot of strange things.

If the homelink is activating two garage doors with one button press (ie no on is playing a prank on you), then it would appear to be an issue with the security of the garage door system... do they have 'master codes' or a situation where a single transmitter blast can activate two different doors that are (presumably) set to two different codes?

Could two buttons in the homelink be programmed: one for each of the doors, and you pressing one button is somehow causing both to be transmitted (both buttons pressed or homelink transmitter sending both signals in sequence)?

I only have the one home door programmed into the cars remote, the left button with 3 dots. It opens the door where the P'car lives.The 2 dot button is clear and the 1 dot button on the right is set for our families vacation home that is 100 miles away.

As the doors and their openers were just installed 2 months ago I called the door guy. He said he's never seen it happen himself but he's heard it can happen. I cleared the offending opener by pushing the "learn" button for several seconds. I then had to reprogram the handheld remote, and then my wife's X5, which requires a handheld to program just like our 997s. All seems to be fine now.

As far as the spoiler goes, It was only about 65 degrees when the car was parked. I have only noticed one previous instance when the cars engine compartment fan came on after engine shutdown. It was over 90 degrees and only the fan was on, the spoiler did not rise.
