All four of these vehicles share the same platform, door construction, steering column, and the same lock system. Three were introduced in the 2007 model year, with the Chevrolet Traverse introduced for the 2009 model year. All four use the GM Z-Keyway system and the “Circle Plus” transponder system. All can be programmed with the standard GM on-board programming procedure, which takes 30 minutes. Advanced Diagnostics, Hotwire, and Silca have recently introduced software for their machines that allow you to program these vehicles with a reduced delay period.
The code series is G001 – G3631, and the only place you will find the code on the vehicle is stamped on the rear of the ignition lock plug. Because the ignition lock must be turned before it can be removed, it’s usually easier to make a key from the door rather than by attempting to pick and removing the ignition lock. The door and rear hatch (if equipped with a lock) use positions 3 – 9, and the ignition uses positions 2 – 10. If there is a glove compartment or console lock, it will use positions 7 – 10. Cut number one is not used by any lock on the vehicle. This allows you to get eight out of nine of the active cuts from the door and compartment lock, if the vehicle has a locking compartment.
The easiest route for making a key is usually to decode the door lock and then progress positions 2 and 10 in the ignition lock. Since this is a relatively small code series, with only 3631 combinations, most fill programs will generally come up with only one or two possibilities after the door lock has been decoded.
The door lock is difficult to remove, so my preference is to decode the door lock with the GM-67 Determinator tool. After cutting a working door key on a B-106 key blank, I’ll use a fill program to progress the remaining two cuts. Only after I have a working mechanical key, will I copy that onto a transponder key and then program the vehicle.
On a side note, the general door lock removal procedure (not the panel removal) will also apply to the 2005 – 2009 Cadillac SRX and 2010 Chevrolet Equinox. The lock used on the SRX is similar to the one used on the vehicles covered in this article, but made by Huf rather than Strattec. The lock used on the Equinox in 2010 uses the new side-milled GM “Flip-Key” system, but is held in the door in the same manner as you’ll see below. In 2009, the SRX got the new GM “Freewheeling” door lock that is also used on the new Camaro and other vehicles. For the 2011 model year, the Equinox also got the new “Freewheeling” door lock. All “Freewheeling” door locks can be removed from the door easily by loosening a single screw.
Most of the photos in this article were taken of a 2009 Saturn Outlook (Photo 1), but will apply to the Buick Enclave, Chevrolet Traverse, and GMC Acadia.
All doors on these vehicles are equipped with vertical linkage rods inside the door. The easiest way to unlock them is to attack the vertical linkage on the rear door with the Tech-Train 1017 tool. As with most modern vehicles, these SUVs are equipped with multi-layer weather stripping. In photo 2, I’m using a shim to separate the weather stripping from the glass, and then I insert a wooden wedge between the shim and the glass. This prevents the lower layer of weather stripping from rolling under my wedge. If I allowed the weather stripping to roll under, it would make it harder to insert a tool and it might damage the weather stripping. The vertical lock button on the rear door is located near the back of the door and I’m wedging open a gap just forward of the lock button.
The TT-1017 tool is equipped with two small hooks that will be horizontal once the tool is inside the door. The hooks face in opposite directions so you can grab the linkage from either side, depending on which end of the tool you insert into the door. In Photo 3, I’m inserting the tool so that I can grasp the linkage rod from the side that is closest to me.
The transponder programming for the Grand Prix is a little odd, so you need to pay particular attention to the section in this article on programming.
