Automotive Locksmith Key Programming

Modern cars require some type of key programming. Depending on the model and make the procedure could be as simple as using an extra key to programme the computer onboard, or as complicated as OBD2 programming or EEPROM.


Most US and Asian auto manufacturers use the same programming protocols as auto tool makers, so they can develop tools or hardware for locksmiths in the automotive industry.

Transponder Chips

Transponder chips are found in a lot of modern cars to stop theft of cars. These are tiny computer microchips that emit low-level radio signals. They have 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 stop the engine. This technology has proved to be an incredible success in preventing auto theft. This technology has also helped car owners save a huge deal of money since they don't have to replace their vehicles.

The basic idea behind the transponder system is to make it difficult for thieves to get into your car without a key. In the past car thieves used a flat screwdriver to force the ignition switch of your vehicle into "on" mode, or hot-wire it in order to bypass the system. Transponder chips have dramatically reduced these types of thefts.

When you insert the transponder keys in the ignition, the signal is received by an antenna that is concealed around the barrel. This antenna is programmed to detect the specific frequency of the chip within the key. The car's onboard computer will recognise that the key is legitimate and allow fuel to flow, power up the starter or start it.

For example an "smart key" which allows you to summon your car into tight parking spaces, like the Genesis GV60, Tesla or Genesis GV60.

A professional locksmith is more equipped to connect your computer to the car via the OBD port located under the steering wheel.

The majority of key fobs come with security features to make it more difficult for criminals to clone and replicate the signals they transmit. These include pseudo-random sequence generators that generate a fresh unlock code each time you press the button on your key fob. This stops attackers from recording and replaying the unlock signal in order to gain access to your car.

The cost of a key fob may differ based on the vehicle model and the type of key however they usually cost between $85 to $400. This includes labor costs to program the keyfob and any replacement parts.
