GMC Key Duplication: Options and Process

Whether you need a duplicate key for convenience or have lost all your keys, GMC key duplication can be done in several ways. Depending on your needs, you can buy pre-cut keys online and program them yourself, visit a dealership or locksmith store, or opt for a mobile locksmith service that comes to you. Each method has its pros and cons, so it’s important to understand what works best for your situation.


Buying Pre-Cut GMC Keys Online and DIY Programming

Duplicating a GMC key can be a cost-effective option if you purchase a pre-cut key or remote online and program it yourself. Some older GMC models allow DIY programming, while newer models may require specialized tools.


DIY Key Programming Instructions

  1. Insert the original key into the ignition and turn it to the "ON" position without starting the engine.
  2. Wait for the immobilizer light to turn off (if applicable), then turn the key back to "OFF" and remove it.
  3. Insert the new key and turn it to the "ON" position.
  4. Wait for the immobilizer light to go off again, indicating the key has been programmed.

DIY Remote Programming

For keyless entry remotes, follow the following instructions to program the remote yourself. Older GMC models may allow manual programming, while newer ones may require professional tools.


Keys That Require Professional Programming

Some newer GMC transponder and smart keys require specialized diagnostic tools for programming. Dealerships typically refuse to program aftermarket keys, so a locksmith is often the best option.


Pricing for Key Duplication

  • Pre-cut standard key: $30 - $100
  • DIY remote programming: Free (if supported) or $50 - $100
  • Transponder key with locksmith programming: $100 - $250
  • Smart key with locksmith programming: $200 - $500


Duplicating GMC Keys at a Dealer or Locksmith Store

Another option for duplicating your GMC key is to visit a dealership or locksmith store. Dealerships have direct access to your vehicle’s key code and can provide a key that is cut and programmed to work with your vehicle’s security system. Dealerships often charge more for key duplication, typically between $150 and $500, depending on whether you need a traditional key, transponder key, or smart key.


Locksmith stores can be a more affordable alternative to dealerships, and many locksmiths have the same tools and technology to cut and program GMC keys. The cost for duplicating a key at a locksmith store usually ranges from $100 to $350, depending on the type of key and the model of your vehicle.



Duplicating GMC Keys with a Mobile Locksmith

For added convenience, mobile locksmith services offer key duplication at your location. Whether you’re at home, work, or stranded on the road, a mobile locksmith will come to you and provide key cutting and programming services on-site. This option is especially useful if you’ve lost all your keys or can’t drive to a dealership or locksmith shop.


Mobile locksmith services typically cost between $150 and $350, depending on the key type and the complexity of programming. This method offers the convenience of having your GMC key duplicated without the hassle of towing or traveling.
