you do nto have to take it to the dealer,, if you look through some of the
threads you can find instructions on how to do it....sounds like other dude
has a problem... i mean if its that big of a deal do not read the thread

I did the same thing, but i found that the instructions were very easy to
follow! Here they are:

1. Locate the Data Line Connector (DLC) underneath the driver's side
dashboard. The DLC is typically located either to the left or the right of
the steering column base. Notice how the DLC is tapered on both ends: you
will be working on the wider row of cavities
2. Insert keys in Ignition and leave in the off position.
3. Make sure there are metal contact pins in terminals 1 and 4 and connect
the Data Line Connector (DLC) terminal 1 to terminal 4 with a suitable
jumper wire, leave the jumper wire connected throughout the programming
procedure). Make sure you know which terminals are 1 and 4.
4. Within 10 seconds after connecting the jumper wire, press the Hazard
Switch 6 times. (Note) The doors will automatically lock and unlock once at
this time indicating that the system is in the programming mode.
5. Press either the lock or unlock button on the transmitter to be
registered three times within 10 seconds. Upon successful
programming, the door will lock and unlock once.
6. Repeat step 5, with any other remotes to be programmed (up to four
remotes) (including any existing remotes), within one minute. After
completing each programming, the doors will lock and unlock once.
7. Disconnect the programming wire and remove the keys from the
ignition.

For the jumper wire, i was able to use Paperclips... they worked great! If
you want, have someone else in the car to press the hazard switch and the
remote while you hold the paperclips together!
