1997 Isuzu Trooper key fob / remote programming

Postby krepster » Wed Jun 14, 2017 12:58 am

So chances are everyone else figured this out about a decade ago and I'm the last person to have this problem. But just in case there's someone else out there in 2017+, let me help you... I just spent two hours trying figuring this out!

So I primarily was trying to follow Tad's instructions here https://forum.planetisuzoo.com/viewtopic.php?t=1929 with no luck.
I read on other websites about removing the panel under steering column for access... What panel are they talking about?? How do you get the Panel off??

First I thought that this was the remote entry box as it was next to the steering shaft and was roughly the right size.

No button on it. Thought that maybe it was aftermarket or an early 98 style entry system so I tried the 98 - 01 instructions for a long time. :banghead:
Even tried unplugging and plugging it back in :shock: Ooops... I don't even know what this box is for... Anyone know? Did I mess anything up?

Anyway, after much more internet research and trying every combination of key turns/door openings/button presses, I crawled under there again and just by chance spotted the CORRECT BOX mounted up high against the left dash wall.

As you can see there are no white papers or yellow buttons, it is a GREEN BUTTON. It's a pain in the neck to access since I couldn't figure out how to remove any panels. Used a long twig.

I originally turned the key to on, depressed the green button with said useful twig and pressed the lock (indented) button on my remote. This successfully programmed the remote to unlock the doors, but not lock them :|
After messing around a bit I tried performing the same procedure with the door "closed" (just inserted a another chunk of repurposed organic matter into the door switch) and viola! It works!

They were no beeps, horn honks or anything like that.

So to recap:

Close door switch
With key to OFF press and hold green button
Turn key to ON
Press top button on remote
Release green button and test for function

You may have to play with the timing of the steps, I think I did it all in quick succession.

Now according to my original 97 key fob manual the top button locks-->unlocks_driver_door-->unlocks_all_doors in that sequence. The bottom button is reserved (useless) for future applications. I don't know if it always worked this way, but on my remote either button works to lock or unlock the doors. I would have preferred if the top locked and bottom unlocked, but hey, I've got a working remote on a 1997! How cool is that! :mrgreen:

The correct key fob for the 1997...

Hope this helps at least one other 97 Trooper owner in this century...

I could be wrong (usually I am according to my ex-wife but that's a different story.) but I think that is the auto trans position indicator brain/doodad.

The more info we can post on this board the better it shall serve those inheriting our vehicles. Good on you!

Thanks! I will have to investigate what this "auto trans position indicator brain/doodad" does...
It wouldn't be the didlywop that supposedly learns your driving style would it?
Well either way it was driving fine this afternoon!

Glad to say this thread is still helping someone, not sure if its the same procedure for my 96 but I sure will give it a shot. a few other post I've seen say the bottom or second switch is to lock and unlock the back doors (barndoors) but I have never figured out how to program my remote until now. Will report back with my findings and hope someone can be excited about it with me.

So I used this old thread to find exact location of keyless unit. I apparently do not have one. What I was wondering is if I could add a used factory keyless entry system. And was hoping a plug was hanging out in the area that it would just plug right into...probably not but a fellah can hope. Any insight you may be able to add would be greatly appreciated.

So I'm trying to add a 2nd remote to my 1997 SLX (Trooper) and I have the module with a green button. I have tried for 2 days to get it to pair this new remote and it won't go into programming mode. My alarm light that flashes when opening the door or goes solid when arming, it never comes on, no horn, no chirp, no exterior lights. I've tried pressing and holding the green button and pressing the remote. I've followed every post in this thread, the one that pointed me to this thread, northwestkeys site. I can not get it to work. I've pulled the module and using a multimeter can confirm the green button is working as it is supposed to, the grounds are good. My 1st remote does work like it should. The new remote has the same FCC ID and everything. Good batteries. Any one got any suggestions?
