If you're looking to pick up a new key fob, or repair one, you might wonder how long programming it takes and whether or not you can do it yourself.

Several car manufacturers require the use of special scan tools to reprogram their key fobs. Some license those tools out to locksmiths and auto repair shops.

If you're in a pinch and need a new copy of your car key, Ace Hardware may be the better alternative over the dealership, but it depends on what car you own.
