Didn't really work for me.
Customer Rating: 




I bought this product because my car locks have a tendency to freeze in the wintertime, whenever there is a thaw and then a freeze soon afterward; my only alternative is leaving my car door unlocked. I got this product, and one morning when my locks were frozen, I tried it out. You put the narrow nozzle a little ways into the keyhole and it shoots fluid directly into the lock mechanism. Nifty, except that after applying, trying the lock, applying again, trying the lock, waiting, trying the lock, trying my other car door.... it still didn't work. Was still late to work and still had to leave my car unlocked. The second time I tried it, the same thing happened, only after 15 minutes or so one of the locks did finally pop open. So, it did work eventually, once, but I don't feel confident that I could get it to work again. So I'm still leaving my car unlocked. It could be that my car is older and that this would make my locks in particular harder to unfreeze, but if so, then they need to say so on the product information, because when I buy something that's supposed to de-ice car locks, I expect it to do its job. I gave it 2 stars because it did work once, and having it work once is, I suppose, better than not having it work at all; however, as I said, I do not rely on it to work again, so if I absolutely have to get into my car, I still don't lock my door.
