This may seem like a silly question, but is the transponder portion of the key needed to unlock the driver's or passenger doors? I'd like to get a copy made of my key without the transponder portion, just a flat key I can slip in my wallet; I have a weird habit of locking my keys in my car once or twice a year and have always kept a spare in my wallet for just such an occasion, saves a bunch of time over calling AAA and having the guy slim-jim it open while my engine's running!
So if I go to a hardware store and just have them cut the key onto a flat blank, will it open the car, or do I need the bulky transponder part to unlock the doors? That's all it has to do, obviously, is unlock the door so I can get my locked-in keys out, I don't want it to be able to start the car or open the glovebox or anything else of course, so even if I have my wallet lost stolen the key won't let anyone get away with my car, too.
