Replacement car keys can also be placed in a magnetic key box and affixed to the underside of the vehicle. However, this is not typically the best way to keep a duplicate car key handy, since corrosion, running over snow or slush, or a particularly nasty pothole might dislodge it. Concerns about having your vehicle stolen are also a factor, when car keys are easy to find. 


Car key replacement is simple when you have the original or a good duplicate key to work from. Most places that cut car keys will have the right key blank for your make and model, and can cut a very good spare in minutes. These replacement car keys usually cost just a few dollars, so having an extra set at home, and even at work, will be a cheap way to save yourself some hassle. If you’re prone to misplacing your car keys, this is an absolute must!
