If you need to program your 2012 gmc terrain key fob, there are several things you need to know. Some of them include the different ways you can do it, how to program a new key, and how to clean your old key fob.
Disassemble the remote key fob
If you have recently purchased a 2012 GMC Terrain and are looking for a way to replace the key fob, you may want to disassemble it. This allows you to see what exactly is inside the device. The GMC Terrain offers several features and options, including Bluetooth connectivity, USB input ports, and streaming audio. You will also find that it has more room than many mini-SUVs.
In order to safely and securely disassemble the key fob, you will need a flat head screwdriver. Next, you will need to turn the key fob over to the other side to release the old battery.
Once you’ve removed the old battery, you will need to place the new one into the remote key housing. A CR2032 3 volt battery should be used. Place the negative side down, and the positive side over it. Make sure the battery is flush with the edges of the case.
Program the new one
The GMC Terrain key fob is a smart device that lets you lock and unlock the vehicle using a programmable chip. It also comes with an emergency key. If your key fails, you can use the emergency key to open the doors and start the car. However, it is important that you program your new key fob so that it works properly.
Before you can program your new key, you will need to remove the existing key from your car. This can be done by pressing the “unlock” button on the driver’s side door. Once the key is unlocked, remove it from the ignition.
Next, you will need to place the new key in the ignition and turn it to the ‘ON’ position for five seconds. After the five seconds, you will need to put the key back in the ignition.

Clean the old one
A key fob is a small device that contains a RFID chip, which is used to power your vehicle. The fob is also useful as a parking aid. If the side view mirrors get knocked off during a tight parking spot, the key can help keep the mirrors in place.
Key fobs come in all shapes and sizes. Most are shaped like a key, while others are hidden. They can be opened by a flat head screwdriver, or a simple pry from the lower half.
One of the biggest problems with key fobs is water. When your key gets wet, it can leak into the case, shorting out the circuit board. This can also result in the battery failing.
To fix a water leak, the first step is to find the source. A clogged sunroof drain line is a common culprit. Other sources include cracked windshield gaskets and transfer cases. These can cost a few hundred dollars to repair.
Replace the battery
If you’ve had trouble locking or unlocking your GMC Terrain, you may want to consider replacing the battery. This is a quick and easy repair that will get your keys working again. In addition, a new battery will extend the life of your key fob.
Before you begin, make sure you have a flathead screwdriver. This will be essential to open the back cover on your key fob. Once the back cover has been removed, remove the old CR2016 and CR2032 batteries.
After the batteries have been removed, you’ll need to snap the halves of your key fob back together. If you use your finger, the sharp edge could split the two halves of your key fob. Then, you’ll need to line up the battery so that it is flush with each side of the fob.
