This DIY is more of a general guide rather than a direct step by step. I may at some point get around to adding screenshots and making this more of a direct write up. For those of you that don't know, 06+ GT's and R3's with the Advanced Keyless Entry & Start system has a feature, that is disabled from factory, when which enabled, allows the car to auto lock the doors when you exit the car and walk away.

Normally, turning this feature on requires a visit to the dealership. When I had the car in for the fuel pump recall, I asked the service advisor to have the tech connect the car to IDS and enable the feature, I was willing to pay for it. The Service Advisor came back to me and informed me when the recall was done that the feature was "already enabled" and something was "malfunctioning" with my system, and it would be a diag fee to continue further. Now, I'm not sure if the tech lied and didn't check it to begin with, wanted to get some money out of me, or if they didn't know how and simply just didn't want to tell me that, or didn't know how to find the feature I was asking about. Either way, after doing some research on my own, I managed to enable this feature on my own, without the dealer "diag fee" (spoiler alert, there was absolutely nothing wrong with the car, and the feature was off.)

This feature is listed in the owners manual as well. I have personally only tried it on Series I GT's, however, I believe Series II GT's and R3's should work with the same method, as they both use the AKE system as well.

What you will need:

Laptop (Windows based, I would not attempt this with OSX running windows via parallels or bootcamp, just out of caution.)
Quality OBDII dongle/cable ( In my case, I'm using my VersaLink USB --> OBDII cable. I would not recommend any cheap ebay bluetooth dongles, as they dont support the HS/MS can, and/or I wouldn't consider them reliable for changing settings on the car. You can try, but its on you if something goes wrong, I take no responsibility for bricking your BCM/PCM, etc using this process or any dongle/cable period. You have the potential to render your car useless and unable to start with the settings you have access to here.)

For the sake of this DIY, I will assume you are using a wired cable.

FORScan - Available for free on their website
FORScan extended License - This can be obtained as a two month trial. You will need to make an account on their forums, which requires admin approval (took maybe a few days in my case to get my account approved.) At this point, you can request your extended license key. Directions for this can be found on FORScans website, and are fairly straightforward.

Once you have FORScan installed and your extended license activated, bring your laptop out to your car (I recommend plugging the laptop in, just in case your battery dies in the process) as well as your OBD II adapter.

Plug your USB --> OBDII cable into your laptop, ensure the cars ignition is in the OFF position.

Connect the OBDII side of the cable to the OBDII port, ensure it is fully connected.

Launch FORScan

Turn your ignition to the 'ON' position, but do not start the engine.

Inside FORScan, you will see an icon in the bottom left, that looks like two plugs joined together, click this button to establish a connection to the car.

After this, FORScan will ask you a few questions about the car (in my case, it asked the model year, and if the car had DSC.) FORScan should now be connected to the vehicle, it will populate some information in the log screen.

Click on the 'Configuration and Programming' icon (it looks like a chip, it is the sixth one down on the left side of the main menu.)

You will see some properties displayed in the main window, you are looking for AKE (Advanced Keyless Entry) It should be listed twice, with one saying "AS BUILT FORMAT" **IGNORE THIS ONE** Select the AKE without the "AS BUILT FORMAT" designation, then click on the "Run Service Procedure" button on the bottom left of the screen, it looks like a play button.

At this point it should launch the procedure, and you should see an option for "Automatic Locks" listed. By default, it should be off. Select it, and change the option to "ON." Then save the changes.

Congrats, as long as there were no errors, you are done! Safely disconnect the session in FORScan, turn the ignition switch to 'OFF' and disconnect the OBDII cable.

Verify the auto locks are now enabled by turning the ignition to the 'ON' position with the door closed, then back to 'OFF.' Exit the car and shut the door. You should hear a callback beep from the car confirming the key has left the car. At this point it is safe to walk away. Once you are out of the designated range, the car will return another callback beep and flash the indicator lights to confirm the doors have locked.

Not necessarily a huge deal, but I find it convenient (as if having the AKE wasn't lazy enough, I didn't want to have to push the request button to lock the door.)
