Are you struggling to replace or add a key fob for your 2011 GMC Sierra? Many GMC Sierra owners have discovered that the convenient in-vehicle programming procedure available in older models was removed starting in 2011. This often leads to the assumption that the only option for getting a new key fob for your 2011 GMC Sierra is a costly trip to the dealership or an automotive garage equipped with specialized Tech II tools. This can be a frustrating situation, as dealership programming can be quite expensive. Discussions in online forums, like this one about Programming Key Fob, 2011 Silverado 1500, highlight the common belief that dealer intervention is the only route.
However, there’s good news for GMC Sierra owners seeking a more affordable and DIY-friendly solution! After extensive research, a cost-effective alternative has emerged: Dorman offers replacement key fobs specifically designed for your vehicle that include an OBD II key fob programmer module. This innovative solution bypasses the need for dealership programming or expensive Tech II tools, putting the power back in your hands. For a reasonable price, typically between $50 and $75, you can obtain a Dorman key fob kit and program your new key fob for your 2011 GMC Sierra yourself.
One such product is the Dorman 99162, which I personally purchased for my 2011 Silverado (compatible with Sierra) from Rock Auto for just $50. This kit allowed me to program two new fobs – one included in the kit and another purchased separately from Amazon – as well as reprogram my original fob. Now, I have a working set of three key fobs without the hefty price tag associated with dealer programming. You can find more details about the Dorman 99162 product at RockAuto Product Page.
The programming process using the Dorman OBD II module is remarkably straightforward. The kit comes with clear instructions, making it accessible even for those with limited automotive experience. Here’s a step-by-step guide on how to program your key fob for your 2011 GMC Sierra using the Dorman programmer:
-
Prepare Your Vehicle: Turn your GMC Sierra’s ignition to the “ON” position. This means the electrical system is active, but the engine is not running. Ensure all vehicle doors are fully closed.
-
Connect the Programmer: Locate your vehicle’s OBD II port. It’s typically found under the dashboard on the driver’s side. Plug the Dorman OBD II programmer module into this port.
-
Initiate Relearn Mode: Once the module is plugged in, your GMC Sierra’s Driver Information Center (DIC) should display a message indicating that a relearn procedure is active. This process mimics the manual relearn available on older GMC models.
-
Wait for the Chime: Allow the Dorman module to initialize. It will signal readiness with an audible chime.
-
Program the Key Fob: Take the key fob for your 2011 GMC Sierra that you wish to program. Press and hold both the “LOCK” and “UNLOCK” buttons simultaneously. When the module chimes again, this indicates that the key fob has been successfully programmed. Release the buttons.
-
Program Additional Fobs (if needed): If you have additional new fobs or existing fobs you want to program (up to a maximum number), repeat step 5 for each fob.
-
Relearn Mode Deactivation: The Dorman module will automatically deactivate the relearn mode when it starts chiming constantly. This signifies that the programming session is complete.
-
Module Usage Limit: Note that the Dorman programmer module has a security feature that limits its use to approximately 3 programming cycles.
By utilizing this Dorman product, you can easily program a new key fob for your 2011 GMC Sierra in a matter of minutes and save a significant amount of money compared to dealership costs. I was personally prepared to pay hundreds of dollars at a dealer based on online information, but this Dorman solution allowed me to program a fob included with the kit, an additional fob purchased online, and my original fob for under $75 total. As long as any separately purchased fobs are compatible with your GMC Sierra model, the Dorman module will effectively program them. This DIY method offers a convenient and economical way to manage your key fob for your 2011 GMC Sierra without the need for specialized tools or expensive professional services.
