I tried it, it works. First you need all of the transmitters ready because you have to clear the code and that will erase the existing codes programmed.
Enter car, close all doors. Insert and remove key from ignition 6 times within 10 seconds. The hazard lights will flash to confirm original code has been erased. Turn the ignition to the ACC position. Press any button on the first transmitter. Hazard lights will flash to confirm programming. To enter additional transmitters, unlock then lock the doors using the power lock switch on the drivers door. Press any key on the second transmitter, the hazard lights will flash to confirm programming. Repeat the unlock then lock step to program additional transmitters. When finished, open drivers door, then remove key. You can have a max. of 4 transmitters per car.
