Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on the model and manufacturer the process could be as simple as using an additional key to programme the computer onboard, or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian auto manufacturers share their programming protocol with auto tool manufacturers, so they can create hardware or software for automotive locksmiths.
Transponder Chips
Transponder chips are in many newer cars to prevent car theft. These are microchips in the form of computers that emit low-level radio signals. The microchips are equipped with an unique serial number that authenticates your keys when you insert it into the ignition barrel. If your vehicle isn't able to recognize the signal, the engine will be shut down. This technology has proven to be an incredible success in preventing auto theft. This technology has also helped car owners save a good deal of money since they don't have to replace their vehicles.
The principle of the transponder system is to make it difficult for thieves to open the doors of your vehicle without the correct key. In the past car thieves used a flat screwdriver to force the ignition switch of your vehicle to go into "on" mode, or hot-wire it to bypass the system. Transponder chips have dramatically reduced these types of thefts.
When you insert a transponder key into the ignition, it will send a signal that is received by a hidden antenna circling the barrel of the ignition. The antenna is programmed to read the specific frequency of the chip inside the key. The onboard computer in the car will recognize the key as valid and will allow fuel flow, power the starter or start the engine.
Some vehicles only recognize certain type of transponder chip according to the manufacturer. It is therefore important that your automotive locksmith is equipped with the correct equipment to program your keys and remotes for your vehicle.
A good automotive locksmith should have an instrument for programming keys for multiple vehicles that works with different car manufacturers and models. This is a less expensive solution than buying individual tools for every brand of vehicle.

The top automotive locksmiths have the tools needed to work on any vehicle. Make sure you choose an established company that has this kind of equipment.
Key FOBs
The key FOBs are programmable transponder chip devices that allow your vehicle to unlock doors and start the engine with the push of a button. It is also possible to press buttons to trigger features such as trunk locks, door locks or fuel flap controls. Some fobs also have additional functions that can be controlled with the button presses for example, a "smart" key fob that lets you get your car into tight parking spots, like you would with the Genesis GV60, Tesla or Genesis GV60.
You can program some replacement key fobs yourself with the help of a user guide, but you'll need to call an automotive locksmith in the event that yours has stopped working. 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 are equipped with security features to make it more difficult for criminals to duplicate and copy the signals they transmit. They include pseudo-random sequence generators that generate an entirely new unlock code each time you press the button on your key fob. This prevents attackers capturing and playing back the unlock signal to gain access to your vehicle.
In most instances you can buy a replacement key fob from the dealer or from another retailer and then have it programmed by your locksmith in your car to work with your specific vehicle. This is because most of the major US and Asian car manufacturers use key fob programming protocols with third-party companies that make the tools that locksmiths for auto use to programme keys for their customers.
While some aftermarket key fobs are advertised as compatible with all vehicles, most automotive locksmiths do not recommend using them as they're likely to work poorly or not at all. Instead, they suggest purchasing fobs specifically designed for your vehicle, so that you are certain they'll work properly and are less susceptible to issues such as interfering or incompatibility. This will save you money over the long term by avoiding costly repairs or replacing the fobs.

The car key fobs are more complicated due to the fact that they use a software system that works with the computer onboard of the car. The software blocks access to unauthorised users by only permitting keys that have been programmed for a specific car to function. This means that if you get your keys replaced, you'll need have the new key fob programed to the car to function.
