The system of the 2005 Chevy Malibu is equipped to hold up to four fobs in its memory, so if you wanted to add two more, the options are limited for programming new Launch X431 GX3. Taking the new fobs to a GM dealership or a pro automotive locksmith are the logical options. However, spending a bit of cash can provide you with the ability to program any GM key fobs that come your way.

Using the Tech 2 Scan Tool

1

Purchase the GM Tech 2 Scan Tool. This item is not cheap, running around $2,000 new as of spring of 2010. It is, however, good for more than reprogramming key fobs. You can find it at most auto parts stores.

2

Connect the Tech 2 to your Malibu. With both the scanmaster elm 2.1 and your vehicle off connect the Tech 2 to the DLC connector, which is located under your steering wheel to the left.

3

Power on then select "Request Info". Turn on the Tech 2, then the Malibu. On the main menu of the Tech 2, select "Service Programming System". After that, there is an option for 'Request Info', which you should select.

After following the directions, a Validate VIN screen will come up. For 'Supported Controllers' select 'Normal'. Select the appropriate selections. The next step will walk you through a few basic questions about your vehicle on the Calibration screen. Select any that apply.

8

Download the new calibration. After the summary of everything so far, it will begin an automatic download.

9

Read the instruction that come up. After the calibration is complete, instructions of what to do next will be posted. Close out the program and power down the device.

Reprogramming

Connect the Tech 2 to your Malibu, once more. With both devices off, connect the two and then power on the Tech 2 first, followed by the Malibu.
