To anyone who does not understand why you would want one of these, all I can say is, if you have ever had one, you will never go without it again. I cant tell you how many times my wife has locked her keys in the car, once with my infant son in the back seat! Yes, we had a hide a key, but it had fallen off. I have a bunch of keys, like 50 or so, so I break them down into two keychains, and then I only have to carry the small one, or none at all. If I am hunting, fishing, water skiing, jogging, or at the gym, why would I want to carry my keys with me. They are uncomfortable to have in your pocket if you wear slacks everyday to work, like I do, or workout clothes are loose fitting with few, and poorly designed pockets. These keypads are the number one item I would choose as ESSENTIAL in any vehicle I ever own. If it does not come with one, I will have it added. The convenience and peace of mind it allows, cannot be matched with a key fob, which will be locked inside right along with your keys when you make a mistake and lock yourself out. Its just a matter of time. Anybody who has had one of these in the past, please comment! We need to have a survey to see what other people think of these things. I guarantee everyone who had one, love them. But that's just my opinion. Thanks.
