Automotive Locksmith Key Programming
Modern cars need some form of key programming. Depending on your vehicle's model and manufacturer the procedure could be as simple as using an extra key to program the onboard computer or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian auto manufacturers have a programming protocol that they share with auto tool makers, which means they can create hardware or software for automotive locksmiths.
Transponder Chips
Transponder chips are found in a lot of modern cars to guard against theft of vehicles. These are microchips in the form of computers that emit radio signals at a low level. They have a unique serial number that authenticates the key to your car when it is connected to the ignition barrel. If your car isn't able to recognize the signal, it will shut down the engine. This technology has been extremely successful in preventing car theft. It also saves many car owners a significant amount of money as they don't have to replace their vehicles.
The basic concept behind the transponder system is to make it hard for thieves to start your vehicle without the correct key. In the past, car thieves would use the flat screwdriver to push the ignition switch of your car to go into "on" mode, or wire it hot to evade the system. Transponder chips have dramatically reduced the number of thefts.
When you place the transponder key into the ignition, the signal is received by an antenna that is concealed around the barrel. This antenna is programmed to detect the particular frequency of the chip within the key. The onboard computer of the car will then recognize the key as being valid and allow fuel flow and power the starter to start the engine.
Based on the manufacturer, certain vehicles can only accept the specific type of transponder chip. This is why it's important to ensure that your locksmith in the automotive industry has the right equipment to program your vehicle's keys and fobs properly.

The best automotive locksmiths will have the proper tools to work on 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 unlock doors and begin the engine with the push of a button ignition. It is also possible to press buttons to activate features such as trunk locks, door locks or controls for the fuel flap. Certain fobs come with additional functions that can be controlled using the push of a button, such as a "smart" key fob that allows you to bring your car into tight parking spots as you would with a Tesla or Genesis GV60.

Most key fobs today have security features that make it difficult for attackers to duplicate or duplicate the signals they transmit. Certain key fobs feature pseudo-random code generators that generate a different unlock code each time you press the button. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.
In most instances you can purchase an alternative key fob from the dealer or from another retailer and have it programmable by a locksmith for your vehicle to work with your particular vehicle. This is because the majority of major US and Asian automakers have key-fob programming protocols with the third-party companies who produce the tools used by locksmiths for programming their customers' keys.
While some of the aftermarket key fobs are marketed as being compatible with all vehicles, most automotive locksmiths do not recommend using them as they are likely to function poorly or not at all. They suggest purchasing fobs that are designed specifically for your vehicle to ensure they will work properly and are less susceptible to issues like interference or incompatibility. This will save money over time, as you avoid costly repairs or replacements for your fobs.

If you change your keys, you'll need to program the new key fob into the car to allow it to function.
