Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the model and make, the process may be as simple as using a spare key to program the onboard computer or as complicated as OBD2 programming or EEPROM.
Most US and Asian auto manufacturers use the same programming protocols as auto tool makers, so they can develop tools or hardware for automotive locksmiths.
Transponder Chips
Transponder chips are in a variety of newer vehicles to prevent car theft. These are small computer microchips that emit radio signals at a low level. The microchips are equipped with a unique serial number that authenticates your key whenever you insert it into the ignition barrel. If your vehicle does not recognize the signal and the engine is 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 hard for thieves to start your vehicle without a valid key. In the past, car thieves would use an ordinary screwdriver to force the ignition switch of your vehicle into "on" mode or even hot-wire it in order to get around the system. Transponder chips have drastically reduced these types of thefts.
When you insert a transponder key into the ignition, it transmits an electrical signal that is detected by a hidden antenna around the barrel of the ignition. The antenna is programmed to detect the specific frequency of the chip inside the key. The computer onboard of the car will then recognise the key as being valid and allow fuel flow, power the starter or start the engine.
Certain vehicles only recognize a specific type of transponder chip, depending on the manufacturer. This is why it's important to ensure that your automotive locksmith has the right equipment to program your vehicle's keys and fobs properly.
A reputable locksmith for cars should have an instrument for programming keys for multiple vehicles that works with different models and car brands. This is a cheaper option than purchasing individual tools for every brand of vehicle. There are also specialised key programming devices for automotive that can only be used on specific brands of vehicles however they are not as common. The best automotive locksmiths will have the appropriate tools to work on any type of vehicle, so be sure you choose a reputable firm that offers these types of tools.
Key FOBs

You can also use the buttons to trigger features such as door locks, trunk releases or control of the fuel flap. Some fobs also have additional functions that can be controlled with the push of a button like the "smart" key fob that allows you to bring your car into tight parking spots similar to the Genesis GV60, Tesla or Genesis GV60.
While some replacement key fobs can be programmed by you with the aid of a user's guide however, you'll typically require an automotive locksmith to have a new one programmed in case yours stops working. This is because a professional 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 beneath the steering wheel.
Most key fobs today include security features that make it difficult for criminals to clone or replicate the signals they transmit. Certain key fobs feature pseudo-random code generators, which generate a new unlock code each time you press the button. This blocks 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 programmed by your locksmith in your car to fit your specific vehicle. This is because the majority of the major US and Asian car manufacturers share their key fob programming protocols with third-party companies that make the tools that locksmiths use to programme keys for their customers.
Although some key fobs from the aftermarket are marketed as being compatible with any vehicle However, the majority of locksmiths in the automotive industry do not recommend using them as they are likely to function poorly or not at all. Instead, they suggest purchasing fobs that are specifically made for your specific vehicle so that you can be sure they'll function correctly and are less prone to issues like interfering or incompatibility. This will save you money over time by avoiding costly repairs or replacements of your fobs.

Key fobs come with built-in security features that prevent hot-wiring (like in a film) and the car will not start if you don't have the right key.

The cost of a key fob can vary depending on the car model and the key type, but they typically run between $85 to $400. This includes the labor to program the key fob, as well as the costs for any required replacement parts.
To complicate the process the car key fobs use a special software system to connect to the car's onboard computer. The software prevents unauthorised access by only permitting keys that have been programmed specifically for a particular car to work. This means that if you get your keys replaced, you'll need to have the new key fob programmed to the car for it to function.
The most common way to accomplish this is using a car key programming tool that is compatible with the model of the vehicle. This tool lets the locksmith connect to the onboard diagnostics port (OBD) in the vehicle and then enter a programming mode. Key programming tools can be a handheld device that is inexpensive device or a more expensive one that is capable of performing a wide range of things beyond just key programming (like reading and cloning eeprom files in the ECU).
Some people attempt to program their keys themselves using these tools. However, this is best left to an experienced auto locksmith.

The computer will recognize the code and add it to the list of keys more info approved by. In certain instances, the scanner will also be able to erase keys that have been stolen or lost from the system.
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. This is why it's best left to a professional who has a lot of experience working on these types of systems.
Locksmiths can program keys quickly using onboard programming. It can take as little as a minute when everything is done correctly. If the key isn't in the right condition or the procedure isn't followed precisely, the procedure could take as long as a half hour.
There are many key programmer scanners available that work with various vehicle models and makes. The Smart Pro and the Autel IM608 Pro are both popular amongst locksmiths because they can be used with a variety of vehicles. However, no system will be able to program every vehicle on the market.
