What Are The Biggest "Myths" About Automotive Locksmith Key Programming Could Be True
Automotive Locksmith Key Programming

Modern cars need some kind of key programming. Based on the car's make and model, the process could be as simple as programming onboard using a spare working key or as complicated as EEPROM or OBD2 programming.

Most US and Asian automobile manufacturers use the same programming protocols as auto tool manufacturers so that they can develop tools and hardware for locksmiths working in automotive vehicles.

Transponder Chips

Most newer cars use what are called transponder chips in order to prevent theft. These are tiny computer microchips that emit radio signals at a low level. They are equipped with a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your car doesn't recognise the signal, it will shut down the engine. This technology has been an enormous success in preventing auto theft. This technology has also helped car owners save a huge amount of money by not having to buy new vehicles.

In the past, car thieves would simply force your ignition switch to the "on" position with an ordinary screwdriver or hot-wire the car to bypass the system completely. Transponder chips have dramatically reduced the number of thefts.


When you insert the transponder keys in the ignition the signal is received by an antenna that is hidden within the barrel. This antenna is programmed so that it can read the specific frequency of the chip inside the key. The computer onboard of the car will then recognise the key as being valid and allow fuel flow and power the starter to start the engine.

Some vehicles only recognize a specific type of transponder chip, depending on the manufacturer. reprogram car key is therefore essential that your locksmith for cars is equipped with the appropriate equipment to program your car's keys and remotes.

For example the "smart key" that allows you summon your car into tight parking spaces, such as the Genesis GV60, Tesla or Genesis GV60.
