High security keys have computer chips and special cuts that are unique to a specific automobile. They make it difficult for thieves to steal your vehicle. However, they are also harder to replicate, and they require professionals to make duplicates.
An experienced automotive locksmith can make a copy of your high security key so you can have a spare on hand in case of emergencies. A mobile auto locksmith can make a copy of a high security key on the scene if you’ve been locked out of your vehicle.
