Automotive Locksmith Key Programming
The majority of modern cars require some kind of key programming. Depending on the vehicle's make and model, the procedure can be as simple as onboard programming using an extra working key or as complex as OBD2 or EEPROM programming.
Most US and Asian car manufacturers share their programming protocols with auto tool manufacturers so that they can develop software and hardware for locksmiths in the automotive industry to use.
Transponder Chips
The majority of newer cars have what are called transponder chips to prevent car theft. These are small computer microchips which emit radio signals of low-level. They have a unique serial number which authenticates your keys when you plug it into the ignition barrel. If your vehicle isn't able to recognize the signal it will shut down. This technology has proven to be extremely successful in preventing theft of cars. This technology has also helped car owners save a huge deal 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 start your car without the proper key. In the past, car thieves would simply force your ignition switch to the "on" position using an ordinary screwdriver or make use of hot-wires to bypass the system completely. These kinds of thefts have been dramatically reduced thanks to the introduction of the transponder chip.
When you place the transponder key in the ignition the signal is received by an antenna hidden around the barrel. The antenna is programmed to match the frequency of the chip in the key. The car's computer onboard will recognize that the key is legitimate and allow the fuel to flow, then power up the starter, or even start it.
Based on the manufacturer, some vehicles will only recognise certain types of transponder chip. This is why it is important to ensure that your locksmith in the automotive industry has the right equipment to program your car's key and fobs correctly.
A reputable locksmith for cars should have a multi-vehicle key programming tool that is compatible with different models and manufacturers of cars. This is a far more cost-effective approach than purchasing individual tools for each brand of vehicle. They are not as common but there are automotive key programming tools that can only be used on a specific brand of vehicle. The best automotive locksmiths have the tools to work on any vehicle. Be sure to choose a reliable company that is equipped with this type of equipment.
Key FOBs

For instance the "smart key" that lets you call your car to tight parking spaces, such as a Tesla or Genesis GV60.

The majority of key fobs are equipped with security features that make it difficult for attackers to clone and replicate the signals they transmit. They include pseudo-random generators that generate a new unlock code each time you press the button on the key fob. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In many cases you can buy a replacement key fob from the dealer or from another retailer and have it programmable by your locksmith in your car to fit your particular vehicle. This is because the majority of major US and Asian auto manufacturers have key-fob programming protocols with the third-party companies who produce the tools used by locksmiths for programming their customers' keys.

The cost of the car key fob is depending on the type and model of key, but it is usually between $85 and $400. This includes labor costs to program the keyfob, as well as any replacement parts.

The software blocks access to unauthorized users by allowing the key to function only if it's been programmed to the car in question. If you decide to replace your keys, you'll need to program the new key fob to the car for it to function.
The most popular method to accomplish this is using an auto key programming tool that is compatible with the model of the vehicle. This tool allows a locksmith to connect to the OBD port on the vehicle, and then enter the programming mode. Key programming devices can be a handheld device that is cheap or extravagant and can do more than just program keys (like reading the eeprom file in the ECU).

You can also program new keys by using EEPROM. It is more complex and requires an in-depth understanding of how electronic systems function. This is why it's best left to a more info professional that has years of experience working with these kinds of systems.
Locksmiths can program keys quickly by using onboard programming. It can take less than a minute when everything is done correctly. If the key isn't placed in the right condition or the procedure is not adhered to, it could take as long as a half hour.
There are numerous key programmer scanners that support various models and makes of vehicles. The Smart Pro and the Autel IM608 Pro are both very popular amongst locksmiths because they support a broad range of vehicle models.
