RE: Range of key
Holding the remote to your chin is actually a pretty common practice for extending remote range, particularly on older remotes. We won't even get in to why it works better for some than others. Replacing the battery in your remote is a better way to go. As the batteries get low on juice your range shrinks until you're unlocking with the key itself.

RE: Range of key
The manual also mentions pointing the metal part of the key directly at the vehicle. Sometimes I get a decent range from the fob to lock/unlock. Other times you have to be within arms reach for it to work. I also replaced the battery about 4 months ago and didn't see a big difference.
