Since I see this topic a lot I figured I'd take some time to post the Honda instructions for it. Please ask questions or request other instructions for diff cars in this thread
Enjoy.
If your car is a Honda and you don't see your vehicle's instructions, either the remote is not programmable or you didn't look hard enough.
e3nine: please link to this in the thread as opposed to pasting it in b/c it's so freaking huge.

Programming the Transmitter
NOTE :
^ The system accepts up to two transmitters.
^ Entering the programming mode cancels all learned transmitter codes, so none of the previously programmed transmitters will work. You must reprogram all of the transmitters once you are in the programming mode.
1. Open the driver's door.
2. Push the driver's power door lock switch to the unlock position and hold it. (Continue to hold the switch during this procedure.)
3. Insert the key into the ignition switch, then remove it. Repeat this four more times (five times total) within 10 seconds. (You must complete steps 3 and 4 within 10 seconds or the system will exit the programming mode.)
4. Insert the key into the ignition switch. After you insert the key, make sure the power door locks cycle to confirm that the system is in the programming mode.
5. Press the "LOCK" or "UNLOCK" button on the transmitter. All the power door locks (except the driver's door) should cycle to confirm that the system accepted the transmitter's code.
6. To program a second transmitter, press its "LOCK" or "UNLOCK" button within 10 seconds of programming the first transmitter.
7. Release the master power door lock switch to exit the programming mode.

Programming the Transmitter
NOTES :
^ The system accepts up to three transmitters. The transmitter codes are stored in a stacking-type memory. If a fourth transmitter code is programmed, the code for the first transmitter is erased.
^ Entering the programming mode cancels all learned transmitter codes, so none of the previously programmed transmitters will work. You must reprogram all of the transmitters once you are in the programming mode.
^ You must complete steps 1-6 within 4 seconds of the previous step to keep the system from exiting the programming mode.
1. Turn the ignition switch to ON (II).
2. Press the "Lock" or "Unlock" button on one of the transmitters. (An unprogrammed transmitter can be used for this step.)
3. Turn the ignition switch to LOCK (0).
4. Repeat steps 1, 2, and 3 two more times using the same transmitter used in step 2.
5. Turn the ignition switch to ON (II).
6. Press the "Lock" or "Unlock" button on the same transmitter. Make sure the power door locks cycle to confirm that the system is in programming mode.
7. Within 10 seconds, press the "Lock" or "Unlock" button on each transmitter. Make sure the power door locks cycle after you press each transmitter button to confirm that the system accepted the transmitter's code.
8. Turn the ignition switch to LOCK (0) to exit the programming mode.

1998-02 Accord EX with factory-installed security system
2000 and 2002 Accord SE with factory-installed security system
(Not interchangeable with CR-V and S2000 remote transmitter)
Transmitter Identification
The transmitter for the 1995-99 Accord and the 2000-02 Accord look identical, but they are not interchangeable. The 1995-99 transmitter works the doors of a 2000-02 Accord, but it does not open the trunk. If you are not sure which transmitter you have, press and hold the trunk release button while looking at the LED. The LED on the 1995-99 transmitter comes on in about 1.1 seconds. The LED on the 2000-02 transmitter comes on in about 0.5 second.
