I had the same problem. I went to a store that specializes in keys and was
told that I had to buy it from the Honda dealership since there was a
computer chip under the plastic. He said that if he made me a key, that my
car would not start since it did NOT have the necessary computer chip.

To do that, all you need to do is to have a key cut. You don't need the chip
programmed, the dealer should do that for you for the regular charge of
cutting the key.

You not only need the key with the chip cut it also has to be programmed in
the car along with all other keys. Try several other dealers. You may find
one cheaper...

You're key is definitely available at locksmiths who do automotive work.
It should not cost $90, substantially less. It also can be cloned
outside of the car, there is a machine that reads the programming of the
 original key and copies it to the new key.

The other responders were correct in that to simply open the doors, you
don't need a programmable key, only a plain metal key. Since your key is
a sidewinder, I believe the aftermarket Ilco key might be the only choice.

Go to a good locksmith, they can service your needs.
