Couldn’T be happier very impressed. Remote start actually is more responsive now from further away. So far, i’m super happy with my purchase glad i got it best deal out there. I used it to replace the old case on my key work well and fit perfectly old rubber. On my g8 key wasn’t, allowing me easy access to unlock my car went and found this shell and swapped. My chip over key makes me feel like i have a brand new vehicle works, just fine fit my pontiac g8p perfectly and functions.
