well the new keys are actually have recharging batteries, while the key's in the ignition. (dun know when they added that in..) and the range has always been the same, short and pathetic, from day one..
andreyiv: there's no need for trunk release on the inside, because you can open it like a door from outside.
since we all have varying models, years, etc. there's bound to be some options that are there, and those that aren't. i know for one, in the first gen a4s, you actually push in the key hole while the car's unlocked to open the trunk. last integras had a latch in the trunk to open the hatch back, so not every car has a release on the inside, but at least a way to open them w/out inserting the key into the trunk.
