Automotive Locksmith Key Programming
Modern cars need some kind of key programming. Depending on the vehicle's make and model, the process could be as simple as onboard programming using a spare key that works or as complex as OBD2 or EEPROM programming.
Most US and Asian automakers use the same programming protocols as auto tool makers, so they can develop hardware or software for automotive locksmiths.
Transponder Chips
Transponder chips are 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 vehicle when it is connected to the ignition barrel. If your vehicle does not recognize the signal, the engine will be shut down. This technology has proven to be an enormous success in preventing auto theft. This technology has also helped car owners save a huge deal of money by not having to purchase new cars.

These types of thefts have been drastically decreased with the introduction of the transponder chip.
When you insert a transponder key into the ignition, it will transmit a signal that is picked up by a hidden antenna around the barrel of the ignition. This antenna is programmed with the frequency of the chip within the key. The onboard computer of the car will recognize the key as being valid and will allow fuel flow and start the starter. start the engine.

Certain fobs come with additional functions that can be controlled with the press of a button like the "smart" key fob that lets you get your car to parking spots that are tight, like you would with a Tesla or Genesis GV60.

The cost of the car key fob can vary depending on the type and model of key, but it is typically between $85 and $400. This includes the cost of labor to program the keyfob as well as any replacement parts.
To make the process more complicated, these car key fobs use a special software system to connect to the car's onboard computer.

This means that if your keys replaced, you'll need have the new key fob programed to the car in order to function.
The most common method to accomplish this is using an auto key programming tool that is compatible with the model of the vehicle. This tool permits a locksmith to connect to the OBD port of the vehicle and then enter the programming mode. The key programming device can be a handheld device that's cheap or extravagant and can do more than just programming keys (like reading the eeprom file inside the ECU).

The computer will detect the code and add it to the list of keys that are authorized. In some cases the scanner will be able to erase keys that have been stolen or lost from the system.
You can also program new keys using the EEPROM. It is more complex and requires a deep understanding of how electronic systems work. This is why it's best left to a professional who has a lot of expertise working on these types of systems.
Locksmiths can program keys quickly using onboard programming. It takes as little as a minute when everything is completed correctly. If the key isn't in the right condition or the procedure is not adhered to, it could take up to a half hour.
There are a variety of key programmer scanners that support various models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due their wide range of vehicle models. There is no system that can program every vehicle. In addition, these machines are quite expensive. It's best to purchase one that will receive regular updates from the manufacturer as new technologies are introduced. Your programming machine will quickly become obsolete if you don't do this.
