2015 GMC Terrain. If you are a GM owner who is in need of some key fob programming information, you have come to the right place. This article will provide you with some helpful information that will help you to find out what you need to do in order to successfully start your vehicle with a keyless start.
Replace the battery
The first thing you need to do if your key fob stops working is to replace the battery. Key fobs can stop working for various reasons, and the problem is usually electrical or due to an internal electrical problem.
You may not realize it, but your key fob can be programmed to work with your car. For example, if you lost your key and you want to make your car start, you can reprogram it with a GMC dealer. This will save you money, and make the replacement go a lot faster.
To program a key fob, you’ll need a code. It is not a difficult task, and there is a simple online tool to help you do it. However, you will need to pay a fee to access the database.
After you get the code, you’ll need to find the right replacement part. GMC has a Learning and Support page that can help you with this. They also offer a number of troubleshooting guides.
If you’re replacing the battery for the GMC Terrain key fob, you’ll need to make sure you get the right size. You can check the size of the battery by turning the key fob upside down and looking at the engraved arrow on the battery.

Test the transmitter
If you own a 2015 GMC Terrain, chances are you’ve experienced the frustration of having your key fob stop working. Fortunately, there are some steps you can take to remedy this problem. First, you’ll need to test the transmitter.
The remote keyless entry system is a popular feature on many new GMC models. It works by transmitting a signal that ignites the engine. Typically, this will keep your car running for up to 10 minutes. But what happens if the transmitter stops working?
In some cases, the issue isn’t with the transmitter. It may be that your key fob isn’t sending enough signal or has a bad battery. Luckily, you can get a replacement and return your car to full functionality.
The key to a successful test is to make sure your car has the necessary batteries. For example, the remote control and the central locking system both need a 12-volt battery. You’ll also want to check for loose batteries, which can lead to corrosion.
You may be lucky enough to have a functioning remote, but you still have to check for the smallest of details. These include how the buttons operate and whether the system works. Some features such as the alarm and the panic button will not work.
Start a car with a keyless start
If you have a 2015 GMC Terrain, you can enjoy the convenience of starting your vehicle from the comfort of your home. Remote start lets you turn on the engine, climate control and heating without turning on the ignition or leaving your house.
In addition to the convenience, remote start is also a safety feature. Some states have laws against car idling in an unoccupied vehicle. The Terrain can start up for up to 15 minutes before automatically shutting off. This is great for days when the weather is cold.
You can even use the remote start function to warm up your vehicle in the morning. The system will automatically turn on the air conditioning, rear window defogger and parking lights. On a cold day, the heated front seats can come on too.
To use a remote start on a Terrain, you must first log into your account through the GMC Owner Center. Once you do, you can begin using the system.
When you press the remote start button on your key fob, you will hear the turn signal lights flash. Holding the button for two seconds will allow you to start your vehicle.
After you finish pressing the remote start button, your Terrain will run for about 15 minutes. During that time, the steering column will lock.
