Automotive Locksmith Key Programming
The majority of modern cars require some form of key programming. Based on the model and manufacturer, the process may be as simple as using an additional key to program the onboard computer or as complicated as OBD2 programming or EEPROM.
Most US and Asian auto manufacturers have a programming protocol that they share with auto tool manufacturers, so they can create hardware or software for automotive locksmiths.
Transponder Chips
Most newer cars use transponder chips to prevent car theft. These are small computer microchips which emit radio signals of low-level. The microchips have a unique serial number which authenticates your key when you plug it into 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 theft of cars. This technology has also saved car owners a great deal of money since they don't have to buy new vehicles.
The fundamental idea behind the transponder system is to make it difficult for thieves to open the doors of your car without the proper key. In the past, car thieves would force the ignition switch of your car into the "on" position with an ordinary screwdriver or use hot wires to disable the system completely. Transponder chips have drastically reduced the number 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 read the specific frequency of the chip within the key. The onboard computer of the car will then recognise the key as valid and will allow fuel flow, power the starter or start the engine.
Some vehicles only recognize certain type of transponder chips depending on the manufacturer. This is why it is crucial to make sure that your automotive locksmith has the right equipment to program your vehicle's keys and fobs correctly.

For instance the "smart key" which allows you to summon your car into tight parking spaces, like the Genesis GV60 or a Tesla or Genesis GV60.
You can program spare key fobs by yourself with the help from the user guide, however you will need to call an automotive locksmith if the one you have isn't functioning. A professional locksmith is better equipped to connect the computer of your vehicle to the OBD port located under the steering wheel.
The majority of key fobs today come with security features that make it difficult for hackers to duplicate or copy the signals they transmit. Some key fobs have pseudo-random code generators which generate a different 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 instances you can purchase a replacement keyfob from an authorized dealer or another retailer. The locksmith you choose to use will then program it to work with your vehicle. This is because the majority of major US and Asian automakers use the same key-fob programming protocol with the third-party firms who create the tools used by locksmiths for programming their customer's keys.
Some aftermarket key fobs may be marketed as being compatible with all vehicles. However, professional locksmiths strongly discourage using them as they are likely to work poorly or not at all. They suggest purchasing fobs that are designed specifically for your vehicle so that they will work properly and are less susceptible to issues like interference or incompatibility. This will save money over time by avoiding costly repairs or replacements for your fobs.
