The Cons of GMC Remotes

  • Limited functionality: The functionality of your car key may be restricted depending on the model of your GMC vehicle and its type. For instance, some remote controls might let you lock and unlock the doors, while others might also have keyless access or remote starting capabilities. You should switch to a more expensive remote or look into aftermarket solutions if you want more sophisticated functionality.
  • Battery life: GMC remote controls need batteries to work, just like any other electronic key or gadget. Your remote’s battery may start to lose power over time, resulting in limited usefulness or the need to replace the battery entirely. 
  • Cost: The price of a replacement remote might be rather costly, depending on the model of your GMC car and the kind of remote you have. This is particularly true if you require a remote with sophisticated capabilities like keyless entry or remote start. Also, you might have to spend a lot of money on a replacement remote if you lose it or it gets damaged.

How To Program A GMC Key Fob

The easiest way to program a GMC remote and button to your car is to go to a dealership or auto shop, which will program it for you. But this will mean a higher price tag for you. A GMC vehicle is straightforward to program with the transponder; see how easy it is here. Skip the dealer and shop to save money and get a much lower price. Try out these quick steps to program your GMC key fob.

Step 1

Take a seat inside your car. You must be close to both the inside locks and the ignition. Make sure you are seated comfortably and that the steering wheel and locks are within easy reach of the keyless remote.

Step 2

Lock all of the car’s doors. The vehicle won’t sync appropriately if any doors are not shut tightly. If possible, yank each door handle from the inside to ensure it is closed as tightly as possible.

Step 3

The ignition lock cylinder should receive the ignition key. Don’t turn the ignition switch because if you do, the cycle will be messed up, and you will have to restart.

Step 4

To unlock the driver’s door, press and hold the button. Not the remote, but the door’s switch. Keep the lock tight; you’ll have to start over if you let it go.

Step 5

Cycle the ignition ON, OFF, ON, OFF, ON, OFF while keeping the door lock switch in the unlock position. The ignition should only be turned as far as it will go before the engine starts. You should refrain from starting your car. A light on the dashboard should come on each time you flip the key to the ON position and go out when you turn the key to the OFF position. Perform this action fast.

Step 6 

Disengage the door unlock lever. When the program mode is on, the doors lock and unlock once. You will have to start the process over if the door only locks or only unlocks. It’s possible that something was out of sync, or you didn’t switch the ignition on or off quickly enough.

Step 7

Press and hold the lock and unlock buttons on the keyless remote simultaneously for fifteen seconds. While you press both buttons to confirm the transmitter’s programming, the doors will lock and unlock. When turning the ignition on or off, you should do this within ten to twenty seconds. 

Step 8

You can program up to four transmitters by repeating the preceding process. Again, only let a little time pass between transmitters. Otherwise, you’ll lose connection with your vehicle and have to restart the process.

Step 9

Flip the ignition switch to the ON (one more click forward) position to exit the keyless entry transmitter mode. Your automobile might only lock or unlock properly if you remember to complete this step. 

Step 10

Use the transmitter’s features to test if the system is functioning correctly. Leave your car and walk up to 20 feet. Check the transmitter’s locking system. If it works from there, move back another 20 feet (40 feet) and try again. You may need to start the sync cycle afresh if it isn’t working. That can also be a sign of a low battery.

Purchasing a Replacement GMC Key Fob

We know you need a new key. But how do you ensure you get a high-quality one, the service required, and the necessary shipping? Here’s what you should know.

Also, note that GMC keys vary. You can select the tested features you want for your car. This also means you will have more say in the price. For example, if you choose the most basic keyless entry remote fob, you might pay less than $30.

However, the items with more features will cost over $100. The price will vary by your car’s year, make, and model. It will also depend on where you purchase your remote. For example, a dealer will charge more than shopping online and placing an order with an online store account.
