An Auto Locksmith is a locksmith that specializes in vehicle locksmith services. Automotive locksmith Charlotte NC services usually include car lockouts, reproduction of new keys, cutting keys by code, auto keys duplication, broken key extractions, transponder keys, and fobs programming, and ignition and door lock repairs. Cars produced in the UK since 1995 are legally required to be fitted with an immobilizer system. These cars require a key with an embedded electronic transponder to start the vehicle. When the key is turned in the ignition the code is read and the vehicle will only start if the correct code is received.

This system was introduced to help reduce vehicle crime. If the transponder key is missing or faulty the car will not start.

Lost car keys can be replaced by a specialist auto locksmith. A good auto locksmith will be able to cut a new car key, clone the transponder and reproduce a key fob that activates the vehicles central locking system.
