Underneath this there will be a square yellow button. This is the programming button.

Now that you have located the yellow button you can begin programming.

To start with, turn ignition key from ON then back to OFF.
Push and hold the down the yellow programming button.
Speaker should emit four single tones followed by a multitone burst. Speaker will then start emitting single prompting tones at one second intervals.
Release the yellow button once the propting tones begin.
Each prompting tone is the time to enter a tranmitter code.
After a propting tone, press the LOCK button only of a transmitter. Speaker should immediately emit a confirmation tone.
If you have another transmitter then wait for another prompting tone and then press LOCK button of second transmitter.
Repeat untill all of your transmitters have been programed
Once finished just turn ignition key from ON to OFF to exit the programming mode.

My question ...

I found this thread while attempting to program a replacement remote for a 96 Protege that my Mom gave to my daughter. I see the security box under the dash and I see the yellow button. Before I venture down this road, I decided to post because I have replaced the Original radio with an aftermarket unit. Since the instructions say that tones will be emitted from the speaker, I am asking if the original radio is required for these tones to be emitted. I did not splice any wires when the radio was replaced. An adapter plug was installed to adapt the original wiring to the new head unit. So, the question is, before I attempt this, the question is will I receive the tones once the unit goes into programming mode. I only want to add 1 replacement remote, so will the original remotes remain programmed if I attempt to add 1 remote, or, do I have to program every remote I intend to use when I attempt this procedure.

Thanks in advance,
Steven
