What Does an Auto Locksmith Do?

Written by

Cars are not just a car anymore; they’re high-tech devices with high-tech security measures designed to prevent them from getting stolen. But what about when those very same measures lock you out of your car, or the key gets lost or broken? That’s where an auto locksmith is needed. These locksmiths are educated to handle automobile lock and key issues without damaging the vehicle, and their profession has expanded during recent years with more advanced automobile technology.

Learning about the Auto Locksmith’s Role

An auto locksmith is concerned with the keys, locks, and security of vehicles. They are not just traditional locksmiths dealing with home or business locks; they deal with car security. Whether locked out of their car, experiencing a stuck ignition or broken key fob, these professionals are normally in a position to fix issues on the spot and for an affordable fee.

As one veteran locksmith himself put it:

“A great auto locksmith does not just unlock doorsโ€”they unlock possibilities for drivers to safely and efficiently get back on the road.” 

Major Job Duties of an Auto Locksmith

Auto locksmiths provide services that are not just limited to opening a car. Their duties are:

1. Emergency Car Lockout Service

One of the most common reasons people call an auto locksmith is when they have accidentally locked their keys in their car. It can happen anywhereโ€”within their house, at a parking area, or even while the motor is still on. Auto locksmiths use a specialized tool to unlock the car without harming the lock or the window.

2. Key Replacement and Duplication

Lost car keys are a true inconvenience. Car locksmiths will make a new key there on the spot for most makes and models, both standard metal keys and more recent transponder keys. Some even copy smart keys and remote fobs.

3. Transponder Key Programming

Most recent vehicles use transponder keysโ€”keys that have a microchip which communicates with the immobilizer system of the car. The vehicle won’t start if it hasn’t been programmed right. Auto locksmiths have the equipment and the knowledge to program or reprogram these keys.

4. Broken Key Extraction

Keys can snap off inside a lock or ignition. When this happens, an auto locksmith uses extraction tools to remove the broken piece without causing further damage, then provides a new working key.

5. Ignition Repair and Replacement

If your carโ€™s ignition is damaged or worn out, starting the vehicle can become difficult or impossible. Auto locksmiths can repair or replace ignition systems and match them to your existing keys.

6. Car Key Fob Repair and Battery Replacement

The smart key fobs go wrong due to electronic issues or a dead battery. Locksmiths diagnose and repair the devices or replace the battery so that the fob functions normally.

7. Car Security System Upgrades

Some locksmiths are specialized to upgrade auto locks, install advanced security systems, or add more anti-theft options to secure the automobile.

The Future of Auto Locksmithing

As more sophisticated security systems become integral to vehicles, the function of auto locksmiths is also evolving. Keyless entry, biometric systems, and digital keys that are connected to smartphones are becoming popular. Auto locksmiths are now developing skills that also include software coding, cybersecurity literacy, and compatibility with smart car systems.

Even locksmiths collaborate with automotive manufacturers to ensure they are up to date with the newest security standards so that they can assist clients without jeopardizing safety.

Final Thoughts

An auto locksmith is much more than someone who unlocks automobilesโ€”they are skilled technicians capable of dealing with the increasingly advanced age of automobile security. Whether you’re stranded in a parking lot with keys locked inside your vehicle, or if you need a high-tech key programmed, these people keep people moving.
