Duracell Self-Programmable 4-Button Remote Key Replacement for GM KOBLEAR1XT - Double Sided Automotive Key Fob | Perfect for Car Lock/Unlock, Trunk Release & Remote Start

Love this product. It works very well. I can even lock my car from inside my home if I forget to do it while unloading my vehicle. It was easy enough to program. But the only problem is that, at times I press on one of the buttons and nothing happens. I'll have to press it two or three time before it works. It doesn't happen very often and I can't figure out what causes this. But Its better than manually locking my car. If I happen to break this one, I will definately buy from them again.
