Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Based on the car's make and model, the process can be as easy as programming onboard using a spare key that works or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian automakers share their programming protocol with auto tool makers, which means they can develop tools or hardware for automotive locksmiths.
Transponder Chips
Most modern cars are equipped with what are called transponder chips to stop car theft. These are tiny computer microchips which emit radio waves at a low level. They have an unique serial number that authenticates your keys when you plug it into the ignition barrel. If your car isn't able to recognize the signal it will shut down the engine. This technology has proven to be an enormous success in preventing theft of cars. This technology has also saved car owners a great amount of money since they don't have to replace their vehicles.
The principle behind the transponder system is to make it impossible for thieves to open the doors of your vehicle without a valid key. In the past, thieves used the flat screwdriver to push the ignition switch of your car into the "on" mode, or wire it hot to get around the system. Transponder chips have dramatically reduced these types of thefts.
When you place the transponder key into the ignition the signal is picked up by an antenna that is hidden within the barrel. This antenna is programmed to detect the particular frequency of the chip within the key. The car's onboard computer will detect that the key is valid and allow the fuel to flow, then power the starter or start it.
Some vehicles only recognize a specific type of transponder chip depending on the manufacturer. Therefore, it is essential that your locksmith for cars is equipped with the correct equipment to program your car's keys and remotes.

The top automotive locksmiths have the appropriate equipment to tackle any type of vehicle, so be sure you choose a reputable firm that offers these types of tools.
Key FOBs
Key FOBs are programmable transponder chip devices that permit your vehicle to open doors and start the engine using a push button ignition. It is also possible to press buttons to trigger features such as trunk locks, door locks or fuel flap controls. Certain fobs can be controlled by pressing buttons. For instance an "smart key" that lets you call your car to tight parking spaces, like the Genesis GV60 or a Tesla or Genesis GV60.
While certain replacement key fobs can be programmed by you using the assistance of a user's manual but you'll usually need an automotive locksmith to get a brand new one programmed if the one you have isn't working. A professional locksmith is more equipped to connect the computer of your car via the OBD port located under the steering wheel.
Today, most key fobs come with security features that make it difficult for criminals to duplicate or duplicate the signals they transmit. Certain key fobs feature pseudo-random code generators, which generate a new unlock code every time you press the button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In some cases you can purchase an alternative keyfob from a dealership or another retailer. Your automotive locksmith will then program it to work with your car. This is because the majority of major US and Asian auto manufacturers share their key-fob programming protocols with the third-party companies who make the tools used by auto locksmiths to program their customers' keys.
While some of the aftermarket key fobs are marketed as being compatible with all vehicles, most automotive locksmiths don't recommend using them since they are likely to function poorly or not at all. Instead, they suggest buying fobs that are specifically made for your vehicle so that you can be sure they'll function properly and be less prone to issues such as interfering or not working. This will save you money in the long run by avoiding costly repairs or replacing the fobs.
