Review on Case Shell Key Fob Keyless Entry Remote Fits Buick Lucerne/Chevy Impala Monte Carlo/Cadillac DTS (OUC60270 by Kevin Gunnmann

The look and quality of these keychains are very good but the function is not very good and I can't understand why. I can arrange the "inside" back to the original, but the body is cracked and everything works fine. Fit the "guts" into this new case, even after fiddling with the battery contacts as others have said there are times when it just doesn't work. About half the time it works fine and the other half it doesn't work at all. And sometimes when you press the lock button once, you will hear a double beep. I haven't tried the other case of the two, but the one I tried to use was a bit disappointing at times. I have to sort of slap/slap my arm or leg to sort of "wake it up" and then it starts to work. Still cheaper than a new fob installed at the dealer or even Revain and doesn't require reprogramming which is a big plus. .
