It took a few attempts but it connected and works well. Very nice replacement at a cheap price. Have patience when you are doing the procedure to connect and don’t get your heart rate up. Ensure you do your original key fob as “remote 1” so that you at least have a working key fob. If it doesn’t work at first, just press and hold the start engine for 12 seconds and it will allow you to continue with 1 remote (may need to do this every time you start the car) until you are able to get it to pair with the car. Totally worth not paying a dealership.

Didn’t have to go to the dealership. Programming with the original remote takes time and patience, my Wifey is very 😃🙏🏿

This is strictly a review on the key fob itself not the process of programming it. Overall this has the look and feel of the GMC keyfob minus the logo on the back. We purchased this to add remote start on our 2019 Terrain since we didn’t buy it from the factory with that option. Overall impressions was it is slightly harder to lock the car with the new fob as you had to press the button harder than the Oem one but nothing we can’t live with, plus now we can remotely start and stop the car so it’s worth the cost. Overall time will tell how long this will last but was worth the money initially.

I had a little bit of an issue programming it. Not the fault of the key or the manufacture, just some weirdness with the vehicle. Once I got it programmed it was perfect! All functions work properly, the fob itself seems like it’s well built, the buttons are tactile and responsive. Overall seems like a great product and value. If at first you can’t get it programmed, try again. It’s annoying to need to go through the 30 minute process multiple times, but it’ll save you hundreds compared to the dealer!

The key was the same as the original 2019 Terrain. Took it to locksmith who programmed it. Less expensive than going to the dealership.
