Key Fob

hint: using that little button up above called "search" could save you $50 bucks
 
You beat me to it, Jack. Use the search function. The truth is out there! ;D
 
PROGRAMING A KEY FOB ? - ? there is a post by Jackalanche with step by step instructions
Look for it:)
 
when searching try diffferent words and set the search date to 300 days so you get all posts.....

The orginal post about this is out there but may have a different title....

Good Luck.
 
In another thread, mikeymcat asked this:
Has anyone tried to disabled the panic button - the only time it seems to go off, is the wrong time!

While I was typing the response, the thread was locked, with a link pointing here. I dunno, I guess this thread is somewhat related, being that it's the key fob, but it is a different question from programming. Oh well.

The worst part, is with that thread locked, it won't let me do a proper quote. I hope mikey finds this answer...

This is what I tried to post in that other thread:


It's easy. In fact, it's a lot easier than it sounds.

Open up your remote, there's a slot on the corner next to the ring - insert a dime or screwdriver and twist.

With the remote in two halves, gently press one of the buttons, and the circuit board and rubber button cover will pop out of the shell.

Gently remove the circuit board from the rubber button cover.

On the back of the circuit board you will see four gold pads, each of which looks like interleaved fingers.

Find the gold pad/fingers that line up with the panic button, and tape a small piece of paper over the gold fingers. Don't cover any of the other pads/fingers by mistake.

This picture shows everything taken apart. The mod is highlighted by the yellow circle:

NoPanic.jpg

Place the board back in in the rubber button cover. Place the board/rubber back in the case. Snap the case back together.

By covering the fingers, you've insulated them from the black carbon contact of the button, thereby disabling that particular function.

The best part is if you want the function back, just remove the tape, and clean the contacts if needed. No permanent changes!

SS - great post - I am going to fix my FOB right now - I hate the panic button going off by accident.

Yeah, it can be fun at times, but annoying at others.

My old Blazer had the same thing, but you had to hit the panic button twice in order to get it to go off. With the Av, it's annoying that only one hit is all that's needed. My false alarm rate with the Av is 10 times what it was with the Blazer.

Of course, even with the double hit, I had false alarms with the Blazer. The best one was when I was in a CPR class. I was demonstrating the CPR for choking on the baby mannequin which involves cradling it in your hand/arm, resting your arm on your leg, and performing the back compressions then switching hands and performing chest compressions. Well, that was enough to push the panic button in my pocket, and the Blazer started beeping/flashing in the parking lot. It was just about time to switch sides, so as I flipped arms, I reached in my pocket, pulled out the fob, turned off the alarm, threw the keys on a nearby chair, and continued with the other side. I barely missed a beat. The class was impressed that I could do that all in one smooth move. I'm just glad it wasn't a real baby at the time. :eek:

Anyone wonder what the 4th pad is for?

(The one without a corresponding button?) ???
 
ShapeShifter, thanks for the info that you originally posted.

Thanks AvavalancheCrazy for using the search button for me! :eek:

I'm off to find the tape!

On my old Blazer, the fourth button popped open the rear lift glass. On a car, it would pop open the trunk.

I wish the fourth button was there for the Av, and it controlled a power tailgate lock!

CraigF, you're most welcome, glad to help!

Hmm, I'm about to do the power tailgate mod and that 4th button could be REALLY useful. Does anyone know if that 4th pad actually sends a signal to the AV at all? I'm guessing it would be more work than it's worth to get the receiver to actually SEND that signal to the tailgate than it would be to just wire it into one of the passenger door locks.

Heck, perhaps one could spefically buy the different style fob that has the 4th button instead of trying to cobble it together. Would just have to have the AV learn the new signal, but still not sure what it would do when it receives an "Open your trunk please" signal.

Yes you can get a four button key fob, and I'm sure you would be able to program the Av to respond to that key fob.

The real question is what will the truck do when it sees that fourth signal. I see only two possibilities:
  • it may igore it
  • it may choke on it and roll over and die :rolleyes:
The problem is that it is up to the software on the body control computer (BCM) to recognize that fourth signal and do something with it, like energize an output that is routed to a lock solenoid. I have previously looked at the outputs from the 2002 BCM, hoping that there would be an unconnected "trunk latch solenoid" connection, but alas, there is nothing with a name even remotely close to that. I can neither confirm nor deny the existance of a suitable output on the 2003 model.

To get this to work with the existing reciever is likely to require finding a suitable unused output, and hacking into the BCM program to get it to understand that command and properly energize the output.

It would be far easier to simply hook the tailgate lock solenoid up to one of the door lock circuits. I would probably choose the passenger's door circuit so that the tailgate remains locked is just the driver's door if unlocked.

SS - I agree that is likely the case and that using a passenger door circuit is the best bang for the buck so to speak. I'll keep my fingers crossed that an electrical guru out there takes a peek and finds an output lead that normally goes to a trunk solenoid but is simply left unconnected on an AV. I'm not holding my breath though as I doubt it's there too. Sure would be kool if it was though. :)

 
GREAT POST! I was always hitting the pantic button. I just did the key fob mod and the alarm will not go off now!!
 
Great post SS. I just did mine and it works fine.

I made one small change. Instead of using paper, I taped over the black carbon contact on the rubber button cover.

That will work, but the reason for the paper is to prevent the gold contact fingers (or the carbon contact) from getting gummed up with tape adhesive residue. The only real concern there is if you ever want to reverse the mod, it will be much easier to clean up the contacts.

My big concern there is that the carbon contact, because it's somewhat porous, will be even harder to clean than the gold plated fingers.
