Car keys are becoming more sophisticated as they and the systems they include not only start your car but unlock the doors, set the alarm and other tasks depending on your car.

Losing the keys means you have to replace a sophisticated system.

Many auto locksmiths are also auto electricians. They need to be: in some car keys there is a device, a transponder, hidden in the tip of the key that responds only to the serial number on your car’s engine. If you want to replace the key, an auto electrician will log in to the car’s computer system and retrieve the pin to load it onto the new key. You don’t necessarily have to go back to the manufacturer – just find a reliable auto locksmith that specialises in your car’s make.

Because they work closely with manufacturers, auto locksmiths help make it easier for you to get back on the road in the event that you lose your car keys. There are a number of variables that come into play when replacing keys, including the car’s country of origin, the model of the car, the year it was made, whether it is a flip-key or a smart key or a regular three-button fob.

With sophisticated car key transponders, immobilisers, anti-theft devices and security lock, a lost car key set can often be a time consuming process. Expert locksmiths attempt to make the complete process time efficient and pain-free as possible.
