How to Change Battery on a GMC Key Fob

It’s important to know how to change the battery on your key fob if you want to make sure your key works properly. A low battery can cause a number of problems, including the inability to unlock your car and locking yourself out of your car. This article will discuss the signs of a low battery on your key and how to replace it.

Symptoms of a low-battery key fob

The key fob is a small remote control that allows you to unlock and lock your car remotely. It is powered by a coin-shaped lithium battery. Most of these batteries last for at least three to four years with normal use.

If you notice that your car doesn’t start when you push the button on the key fob, you may have a dead key. This could be due to a faulty circuit board, a damaged battery, or a broken antenna.

A dead key can be a serious problem. It can be extremely frustrating to be unable to get into your vehicle. You may have to turn your vehicle into the locked position or press the button a few times before the engine starts.

However, the most common culprit is a low-battery. These batteries are often 3-Volts, but they can be less. Having a low-battery will decrease the range of the transmitter.

Keyless entry systems are complex. They require several buttons and a receiver in your car to work properly. Often, if your key is a Smart Key, it requires a battery replacement every year.

Key fobs also include a panic alarm. The alarm can be activated when the vehicle is in motion, or when the ignition is turned on.

How to reprogram a key fob after changing the battery

When the battery in your GMC key fob is low, you may want to consider reprogramming it to make it work again. Reprogramming can be a fairly simple process and will work for most vehicles. Besides, it can save you a lot of hassle down the road.

To reprogram your key fob, first, turn off the ignition. If you’re not sure how to do this, check your owner’s manual. You should also have a spare key that you can use for this.

Next, you’ll need to get a small flathead screwdriver. This tool will help you pry open the seam of the key fob. Once you’ve opened the seam, you should be able to see the button cell battery. It looks like a tiny silver coin.

After you’ve gotten the battery out, you’ll need to remove the circuit board from the fob. A circuit board is where the buttons on the key are built. Care must be taken to not damage the circuit board.

If you’re unable to get the circuit board out, you can try replacing it. Most manufacturers include instructions on how to do this in their owner’s manuals.

If you’re unable to do this yourself, you can take your car to your local GM dealer or an automotive locksmith. They will be able to do this for you.

How much does a key fob battery cost?

GMC key fobs use 3-volt CR2032 batteries. These are available at AutoZone and most hardware stores.

Your owner’s manual will provide you with specific instructions on how to open and replace your key fob. If you are unsure of how to do this, ask an automotive locksmith to help.

A GMC key fob battery typically lasts for three to four years. To replace it, you will need to open the back panel and remove the old one. Use a flathead screwdriver to pry the cover off.
