Applied Models: 1993-94 J30; 1993.5 G20; 1994 Q45
SERVICE INFORMATION:
The proper procedure for programming additional remote controllers is listed below.
SERVICE PROCEDURE:
While sitting inside the vehicle:
1. Open the trunk.2. Close and lock all doors.3. Insert and remove the key from the ignition six (6) times within ten (10) seconds.4. Manually unlock and lock the driver’s door once (1) to enable “setting” mode.5. Push the lock button on the new remote controller once (1), just long enough to hear it beep, within five (5) seconds of completing step 4.6. If additional remotes are needed (up to 3), repeat steps 4 and 5 for each additional remote immediately after programming the first remote.

Very good info, note that this procedure must be followed EXACTLY on the G50, but it does work for up to 4 remotes (i just proved that). here's my notes that may make it easier for first pass success:SERVICE PROCEDURE:
While sitting inside the vehicle:0. close the drivers door.1. Open the trunk.2. (Close and) lock all doors. <<superfluous, as the doors were closed in step 0, but the significant thing is to lock with either the manual finger, or the lock button on the door, but DO NOT use the remote yet.>>
3. Insert and remove the key from the ignition six (6) times within ten (10) seconds. <<Don't expect anything to happen on a G50 at this point. My Y33 will flash the blinkers 2x at this point>> 4. Manually unlock and lock the driver’s door once (1) to enable “setting” mode.5. Push the lock button <<MUST be the LOCK button>>on the new remote controller once (1), just long enough to hear it beep, within five (5) seconds of completing step 4. <<press it twice and you're hosed. again, don't expect anything to happen on a G50 at this point>>6. If additional remotes are needed (up to 3), repeat steps 4 and 5 for each additional remote immediately after programming the first remote.
<<now press a button on each remote to confirm functionality.>>
Note: A total of four (4) remotes can be programmed to function on the same vehicle.
