It can cost significantly less to rekey your car door lock rather than rekeying your vehicle’s ignition. It’s a good idea to ask a professional to make you a new key for your car using the car’s door lock in order to save money. You can save even more money by removing your car’s door lock and taking it to a locksmith shop and having them make a key for you there.
