One thing that I've noticed on my car is that the trunk release button on the key fob seems to be programmed to ignore a quick, accidental push or something. I thought the remote was faulty for a while because I had to push the button four or five times to get it to work sometimes, while the lock and unlock buttons worked on the first try every time. Anyway, when you go to unlock the trunk, just hold it down for a second or two instead of giving a quick push and release. I'm guessing they did that so it wouldn't actually pop your trunk in case you accidentally hit the button in your pocket or something. Anyway, it's easy enough to figure out, but thought I'd mention it in case it saves somebody a few minutes of frustration.
