Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on your vehicle's model and make the process could be as simple as using an extra key to program the onboard computer, or as complicated as OBD2 programming or EEPROM.
The majority of US and Asian car makers share their programming protocols with auto tool makers in order to create tools and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Most modern cars are equipped with what are called transponder chips in order to prevent theft. These are tiny computer microchips that emit radio waves at a low level. They have a unique serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal it will shut down the engine. This technology has proven to be an incredible success in preventing auto theft. It also saves many car owners a lot of money because they don't need to replace their cars.
The transponder system's basic idea is to make it hard for thieves to start your car without the right key. In the past, car thieves used the flat screwdriver to push the ignition switch in your car 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 hidden around the barrel. The antenna is programmed with the frequency of the chip within the key. The onboard computer in the car will recognize the key as being valid and will allow fuel flow and power the starter to start the engine.
Some vehicles only recognize certain type of transponder chips, depending on the manufacturer. It is therefore essential that your locksmith in the automotive industry is equipped with the appropriate equipment to program your car's keys and remotes.
A good automotive locksmith will possess a multi-vehicle programing device that can be used on many different car models and manufacturers. This is a less expensive solution than buying separate tools for each brand of vehicle.

The top automotive locksmiths have the right tools to deal with any kind of vehicle, so ensure you choose a reputable business with these kinds of tools.
Key FOBs

For instance an "smart key" that lets you call your car into tight parking spaces, like the Genesis GV60 or a Tesla or Genesis GV60.
While some replacement key fobs can be programmed by you using the assistance of a user's manual however, you'll typically need an automotive locksmith to get a new one programmed in case yours stops working. A professional is better equipped to connect your computer to the vehicle to the OBD port located under the steering wheel.
Most key fobs today include security features that make it difficult for hackers to duplicate or copy the signals they transmit. Some key fobs have pseudo-random code generators which generate a new unlock code each time you press the button. This is to prevent attackers from capturing and playing back the unlock signal to gain access to your car.
In some cases you can purchase an alternative keyfob from an authorized dealer or another retailer. Your automotive locksmith will then program it to work with your vehicle. This is because the majority of major US and Asian auto manufacturers have key-fob programming protocols with the third-party firms who make the tools used by locksmiths who program their customer's keys.
Certain key fobs from the aftermarket may be marketed as being compatible with vehicles of all kinds. However, automotive locksmiths recommend against using them because they're likely to function poorly or not even work at all. Instead, they suggest purchasing fobs designed specifically for your vehicle so that you are certain they'll function properly and be less prone to issues such as interference or incompatibility. This will save money over time, as you avoid costly repairs or replacements of your fobs.

This includes the cost of labor to program the key fob as well as the cost of any needed replacement parts.
To complicate the process, these car key fobs make use of a special software to connect to the car's onboard computer. The software prevents unauthorized access by permitting the key to function only if it's been programmed for the specific car. This means that if you need your keys replaced, you'll need have the new key fob programed to the car in order for it to function.
This is accomplished using a programing tool for car keys that is compatible with the brand of your vehicle. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) within the vehicle and then enter the programming mode. The key programming device can be a handheld device that's inexpensive or one that is fancy and can do more than just program keys (like reading the eeprom files in the ECU).
