Hand Sanitizer to Breakdown Keyhole Ice 
If you have lived in an area that experiences a lot cold weather and have grown up, then you may be familiar with the problem of frost and ice on your vehicle. It can get into the keyhole and make it difficult to open your car. Alcohol-based hand sanitizers are a great solution to this problem. These hand sanitizers work as de-icers and melt the frost immediately. Spray a little on the area you want to de-ice, wait for a few minutes, then try unlocking the car again.
