If im not mistaken-- the key needs to be 'learned' to the vehicle.
The black part of the key- has a chip or resistor in it.

 

you need at least 1 good key- to be able to program the new key.

 

Adding Keys
Important:

• To initiate, this procedures requires that a learned master key be available.

• A total of 10 keys may be programmed to a single vehicle.

• This procedure adds keys only. The procedure does not erase previously learned keys.

• The keys to be learned must duplicate the mechanical cut of the current key.

• If more than one valet key is to be learned, immediately precede each valet key with a learned master key.


With a previously learned master key, turn ON the ignition, with the engine OFF.
Turn OFF the ignition and remove the key.
Within 10 seconds of turning OFF the ignition, insert the key to be learned and turn ON the ignition. The vehicle has now learned the new key.

Thank you for your reply. The key was only intended to unlock the car in the event that we managed to lock ourselves out, it has no chip. She was trying to open the car to get something out of it and she forgot her ignition key at home. The car starts and runs fine, but the theft light stays on now and it displays the messages continuously. I need to know how to turn off the "Theft Attempted" message.

 

also-- the new key must have the same logo stamped on it
A circle with a + in the middle will be stamped into the metal...
I think Ive seen references to PK3 on other keys--

make sure your new key has the same logo as the working key

Thank you for your reply. I do not need more keys. She was trying to get something out of the car and used a key intended to unlock the car in the event that we managed to lock ourselves out. This activated the theft deterrent system. Now it constantly displays "Theft Attempted". I wanted to avoid going to the only local GM dealership because of bad experiences with them. I would like to know if there is a way for a consumer to disable the "Theft Attempted" message in the DIC that will not go away now.

 

hmmm interesting.

Ive tested the vehicles alarm by
lowering driver side window.
getting out.
locking car with FOB.
waiting till the security light goes out...
then I reach in- and unlock the door lock and open the door.

Alarm goes off. I then stop alarm with FOB.
When I get in-- the DIC shows the THEFT attempted message.
Though upon restarting car-- and subsequent starts-- its gone.....


So im wondering-- if you recreate this--- will this set a 'new' theft message-- which will then be reset by restarting the car..

Im just saying this-- cause its what I would try....

That is a good idea. I will try it sometime tomorrow, I don't want the horn to disturb the neighbors. Thank you.

A key that is cut to only open the door cannot be "learned." It is only a metal key like the ones many years ago. I carry one in my billfold for emergency use. I also carry one on my key ring for my wife's Cadillac. It is convenient when I want to open her car and do not have her keys handy.

Give this a read.

Theft System

To me it seems you just need to arm and de-arm the vehicle. Press - 'lock' twice-->*honk*--> then 'unlock' on the FOB.

I have an extra door remote for that purpose, it is programmed to both my Acadia and my Sierra. It is good to give to the kids to open either vehicle without giving them a key. It has been very handy when needing stuff from one vehicle when we're out at the mall or the arena with both vehicles (like switching booster seats) and it is great in the morning when autostarting both vehicles, done with just one remote.

To the OP, it surprises me that the alarm did not go off when your wife opened the Acadia with the other key.... I'm not sure why the attempted theft message is not clearing.

Why would an alarm go off when the Acadia is opened with a legitimate key? My Acadia's alarm does not go off when it is opened with the cloned key . Just a plain metal key, no chip. That key cost me $1.48 plus tax.

My Traverse alarm--- will go off--- if I open the car with a factory key....and it was armed via fob.

Theres no sensor on the door lock it seems..

If you lock the doors with the FOB, the system will arm the car. If you press lock once it will be in stand-by mode. If you press lock twice with the doors closed, it will be in armed mode. Both modes require the FOB to de-arm or a vaild key in the ignition. Read the doc I posted above.

Important:
Using the power door unlock switch or manually unlocking the doors does not disable the content theft deterrent (CTD) arm mode. Also, disconnecting the battery or pulling fuses does not disable the arm mode, since the BCM stores the CTD mode status in memory.

I don't know why some do and some don't go off... If I walk up to my Acadia with the factory key, put it into the door, unlock the door, and open the door... the horn starts honking and the lights start flashing. To stop that, I need to either start the Acadia with that key, or push unlock on my key fob.

The reason for the key failing to disarm the alarm when used to unlock a door: Anyone can pop the lock out and push/pull the connecting rods to unlock the door. The key in the door just moves those connecting rods, so the Acadia does not know the difference between a legitimate key in the door, a screwdriver, or a slim jim.

I wouldn't have purchased a spare key fob, I just had an extra one from my first Acadia after the DW crashed it and the insurance company took it away.

 

... or a slim jim.

does it know the difference between a regular or a spicy jalapeno slim jim? mmmmmm, slim jim.

Thank you for your response. I have yet to figure out how to correct this issue. There is a town about 15 miles away with a good GM dealership. I believe they will help me. I still don't understand why I should have to pay someone to turn this message off for a false alarm.

 

Did you read the document I posed?

Just read it. Thank you for the information. I will most likely have to go to a dealership.

Have you tried arming and disarming with the remote now (lock / unlock)? and then started the Acadia with one of the original factory keys? That should reset the light if all is well.
