Automotive Locksmith Key Programming
The majority of modern cars require some type of key programming. Depending on the car's maker and model, the process can be as easy as onboard programming using a spare key that works or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian car manufacturers use the same programming protocols as auto tool manufacturers to allow them to develop software and hardware for locksmiths in the automotive industry to use.
Transponder Chips
Most newer cars use what are called transponder chips in order to prevent theft. These are tiny computer microchips that emit low-level radio signals. The microchips are equipped with a unique serial number that authenticates your key whenever you insert it into the ignition barrel. If your vehicle isn't able to recognize the signal, the engine will be shut down. This technology has been an incredible success in preventing auto theft. It has also saved many car owners a significant amount of money because they don't need to replace their cars.
The principle of the transponder system is to make it impossible for thieves to open the doors of your car without the right key. In the past, thieves used a flat screwdriver to force the ignition switch in your car to go into "on" mode, or wire it hot to evade the system. Transponder chips have drastically reduced these types of thefts.
When you insert the transponder keys 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 inside the key. The car's onboard computer will then recognize that the key is genuine and allow fuel to flow, turn the starter or begin it.
Depending on the manufacturer certain vehicles can only recognize the specific type of transponder chip. This is why it is crucial to make sure that your automotive locksmith is equipped to program your car's keys and fobs correctly.

For example the "smart key" that lets you call your car into tight parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.
While some replacement key fobs can be programmed by you using the help of a user manual, you'll often require an auto locksmith to have a new one programmed if yours stops functioning. This is because an expert locksmith has the equipment that is specialized and access to the programming tools needed to connect your car's computer to the on-board diagnostics (OBD) port that is located under the steering wheel.
The majority of key fobs come with security features to make it more difficult for criminals to duplicate and copy the signals that they transmit. Certain key fobs come with pseudo-random code generators which generate a new unlock code every time you press the button. This stops attackers from recording and playing back the unlock here signal to gain access to your car.

The cost of a key fob may vary depending on the car model and the type of key however, they generally cost between $85 to $400. This includes the cost of labor to program the key fob, as well as the cost of any needed replacement parts.

EEPROM programming is another method that can be used to program new car keys. It is more complex and requires a thorough understanding of electronic systems. It is best to delegate it to a professional who has experience with these systems.
Onboard programming is the quickest method for locksmiths to program an entirely new key. When everything is done correctly, it can take as little as one minute. If the key isn't in proper situation or the procedure is not followed exactly, it can take up to a half hour.
There are a variety of key programmer scanners on the market that work with various vehicle models and brands.
