Automotive Locksmith Key Programming
Most modern-day cars require some kind of key programming. Based on the car's make and model, the procedure can be as easy as programming onboard using a spare key that works or as complicated as EEPROM or OBD2 programming.
Most US and Asian car manufacturers share their programming protocols with auto tool makers so that they can develop software and hardware for locksmiths in the automotive industry to use.
Transponder Chips
Most modern cars are equipped with what are called transponder chips in order to prevent theft. These are small computer microchips which emit radio signals of low-level. They have a unique digital serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle does not recognize the signal, the engine will be shut down. This technology has been a huge success in preventing car theft. This technology has also helped car owners save a huge deal of money as they do not have to purchase new cars.
The principle of the transponder system is to make it hard for thieves to start your vehicle without the correct key. In the past, thieves used the flat screwdriver to push the ignition switch of your car to go into "on" mode, or hot-wire it to bypass the system. Transponder chips have dramatically reduced the number of thefts.
When you insert the transponder keys into the ignition the signal is received by an antenna that is hidden within the barrel. The antenna is programmed to detect 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 begin the engine.
Depending on the manufacturer certain vehicles can only accept a specific type of transponder chip. This is why it is essential to ensure that your locksmith in the automotive industry has the right equipment to program your car's key and fobs correctly.

Key FOBs

For example the "smart key" that lets you call your car to parking spaces, such as the Genesis GV60, Tesla or Genesis GV60.
While some replacement keys can be programmed by you using the help of a user manual, you'll often require an auto locksmith to get a new one programmed if the one you have isn't functioning. A professional is better equipped to connect the computer of your vehicle via the OBD port located under the steering wheel.
The majority of key fobs are equipped with security features that make it harder for attackers duplicate and copy the signals that they transmit. They include pseudo-random generators that generate a fresh unlock code every time you press the button on your key fob. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In many 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 specific vehicle. This is due to the fact that most of the major US and Asian car makers use key fob programming protocols with third-party firms that produce the tools locksmiths for auto use to program keys for their customers.
While some aftermarket key fobs are advertised as compatible with any vehicle, most automotive locksmiths do not recommend using them since they will likely only work poorly or not at all. They suggest purchasing fobs that are designed specifically for your vehicle to ensure they work correctly and are less susceptible to issues such as interference or incompatibility. This will save you money over time by avoiding costly repairs or replacements for your fobs.
