Keyless Entry Remote Car Key Fob Replacement for Chevy Trailblazer & GMC Envoy (2-Pack) - Easy Programming, Durable Design | Perfect for Spare Keys, Vehicle Access & Key Replacement Needs

First I’d like to say it’s nothing special, no different than the original fob, same size and everything. Had it for a few months now so not sure on long term durability. However what makes this fob AWESOME, is the fact that I had a big blonde moment and took it swimming with me at the pool. We had been in for about a hour when we had to sit on the side for them to check the pool for cleanliness, and that’s when I felt something in my pocket, whooops I thought there goes that one. But nope, to my extreme surprise it still works perfectly fine. Came out of the pool and it functioned just as it had before being dunked. Went home and popped it open and there was water and some nice rust-like looking stuff. Cleaned it out and let it set overnight to dry. Put it back together and still works well!! We’ll see if the water has any effect on the battery's long term life.I highly recommend this.
