After reading many reviews, I decided that this is the seller to go with and that proved correct. Initial FOB had an issue, but was quickly replaced. I followed the programming directions for my 2019 GMC Terrain and it It works just like the original GM key.

Lost my key and didn’t want to pay the dealership $400 to cut and replace my fob, luckily with this and the help of a youtube video (link included with package). Literally saved me hundreds! I got 2 fobs and took them to the dealership and got both cut for $70 total, saving me a little over $260. This product is a literal GOD SEND.

It was very easy to program the remote to work on a 2019 GMC Terrain SLE with remote start and power rear lift gate , follow instructions in the owners manual. Appears to be identical to the factory fob, other than it doesn't have GMC on it. The hardest part is going to be finding a place to have the blank emergency key cut, I was able to find a Chevy dealer that had the machine to cut the blank. Some Ace hardware store are able to cut the key as well.

Before you go to program your key fob, find a video that walks you through it as the instructions provided are not detailed enough.

I tried YouTube videos, but they really didn't show how long and the exact process.My old Key FOB would get reprogrammed in less than a minute, so when to took longer than 5 minutes I thought this new one was faulty. I had asked to return it and the seller said it was never made for my vehicle even though Amazon said its a perfect fit.I read the comments in YouTube and found out there is written instructions in the vehicle manual.I followed them and the new FOB took 8 minutes for the car to program it. IT WORKS!!! Just a little slower than the originals. Look for the instructions in the manual YouTube zips through it pretty quick and you need to wait till the computer says its ready for next key before pulling it out of the cup holder or the programming location.

It took sometime to install , didn’t go quite as planned but in the long run ! I’m very happy with overall product

Website instructions were not accurate for my vehicle. Key was correct but the instructions had extra step which caused the whole process to have to be started over. Each time takes about an hour so it killed a lot of time I didn't have. Searched and found a YouTube video with the accurate setup which made it a breeze. Seeming there are massively expense through a dealership I am very pleased with the purchase.

Ok, so i am SO glad i tried the third time...something was going wrong but it finally worked, yay!!! thank you and so happy to have a spare now! (also watching youtube videos about this process actually helped me learn a lot about my GMC 2019 terrain, like you can actually start it with a dead battery remote by putting it in the front left cup holder...who knew?? not me!!)

Perfect replacement and easy to put on. I recommend this product.

Do initially I was going to attempt to program the new one, but it’s a lot easier to just swap out the chip. It took all of 2 minutes.

Wow this is much cheaper than the dealer and just the same quality as my factory remote. I had it programmed in just a few minutes and it works great. Recommend to purchase this over the high priced dealer remote.

Funciono excelente en mi GMC Terrain 2018 y muy fácil de programar

I was quoted $314 for a new proximity keyfob from GMC PLUS $190 for programming. Yeah, no. Amazon comes in clutch with this amazing alternative. I simply swapped out the old internals of the busted fob and put it into the new. Then I thought hmm.. can this actually be programmed at home? It sure can! It takes about 35 min from start to finish and you have to make sure you read the instructions fully before you begin. I started with one busted (but working) keyfob, now I have two 100% functioning key fobs. One looks obviously new, and one does not but that’s okay! I actually kept the old keyfob back cover (with the GMC emblem) and put it on the new fob. Fits no problem. You only need one cut key to program! This worked on my 2018 GMC Terrain Denali like a charm. Love it’ 100% would recommend!

This keyless remote is so much cheaper than those you purchase at a dealership and works the same. My used vehicle only came with one remote. So it was essential that I have a spare. So glad I found this one.
