Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on your vehicle's model and manufacturer the process could be as simple as using an extra key to program the onboard computer or as complicated as OBD2 programming or EEPROM.
Most US and Asian car manufacturers use the same programming protocols as auto tool makers in order to create hardware and software for automotive locksmiths to use.
Transponder Chips
The majority of newer cars have what are called transponder chips to prevent car theft. These are tiny computer microchips which emit radio waves of low-level. The microchips are equipped with an unique serial number that authenticates your key whenever you insert it 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 enormous success in preventing theft of cars. This technology has also helped car owners save a huge deal of money as they do not have to purchase new cars.
The fundamental idea behind the transponder system is to make it impossible for thieves to open the doors of your car without the proper key. In the past, thieves would simply push the ignition switch of your car into the "on" position with the flat screwdriver, or use hot wires to disable the system entirely. These kinds of thefts have drastically reduced thanks to the introduction of the transponder chip.
When you insert the transponder key in the ignition the signal is picked up by an antenna that is concealed around the barrel. This antenna is programmed so that it can detect the particular frequency of the chip inside the key. The car's onboard computer will then detect that the key is genuine and allow fuel to flow, power up the starter, or even start it.
Some vehicles only recognize certain type of transponder chip depending on the manufacturer. This is why it is essential to ensure that your automotive locksmith is equipped to program your vehicle's keys and fobs correctly.
A good automotive locksmith should have an instrument for programming keys for multiple vehicles that works with different car manufacturers and models. This is a much more cost-effective approach than purchasing specific tools for each model of vehicle. There are also specific key programming tools for automobiles that are only suitable for specific models of vehicles, but these are less common. The best locksmiths for automotive have the tools to work on any vehicle. Make sure you choose a reputable firm that has this kind of equipment.
Key FOBs
As the name suggests, key FOBs contain transponder chips programmable that enable your car to recognize and unlock the doors or start the engine using push-button ignition. It is also possible to press buttons to activate features like trunk locks, door locks or control of the fuel flap. Certain fobs come with additional functions that can be controlled by the press of a button, such as a "smart" key fob that allows you to get your car into tight parking spots similar to a Tesla or Genesis GV60.
While some replacement keys can be programmed by you using the aid of a user's guide however, you'll typically require an auto locksmith to get a new one programmed if the one you have isn't working. A professional locksmith is more equipped to connect the computer of your vehicle to the OBD port on the steering wheel.
Today, most key fobs have security features that make it difficult for criminals to clone or replicate the signals they transmit. These include pseudo-random sequence generators that generate a new unlock code every time you press the button on the key fob. This stops attackers from recording and playing back the unlock signal to gain access to your vehicle.
In many instances you can buy a replacement key fob from the dealership or another retailer and have it programmed by your automotive locksmith to work with your particular vehicle. This is because the majority of major US and Asian auto manufacturers have key-fob programming protocols with third-party companies that produce the tools used by locksmiths who program their customer's keys.
Certain aftermarket key fobs can be advertised as compatible with any vehicle. However, automotive locksmiths advise against using them since they are likely to work poorly or not at all. They recommend buying fobs made specifically for your vehicle to ensure they will work properly and are less susceptible to issues like interference or incompatibility. This will save money over time by avoiding costly repairs or replacements for your fobs.
Tool for programming the vehicle manufacturers
The automotive industry has advanced considerably and today's vehicles need computer technology in order to function. A transponder chip is an essential component of this technology. Read A lot more needs to be programmed by a locksmith mechanic or dealer to function. Key fobs are fitted with security features to prevent hot-wiring, like in a movie. The car will not start if the keys are not correct.

The cost of a key fob may vary based on the vehicle model and the type of key, but they typically run between $85 and $400. This includes labor costs to program the keyfob and any replacement parts.
Car key fobs are more intricate due to the fact that they use software that interacts with the onboard computer of the car. The software blocks unauthorized access by allowing the key to function if it has been programmed for the specific car. If you decide to replace your keys, you'll have to program the new key fob into the car to allow it to work.
The most common way to accomplish this is using an auto key programming tool that is compatible with the brand of the vehicle. This tool permits a locksmith to connect to the OBD port in the vehicle, and then enter the programming mode. The key programming tool can be a simple handheld device or a more expensive one that can perform a wide range of things beyond just key programming (like reading and cloning the EEEPROM files in the ECU).
Although some people might attempt to program their own keys with these tools, it's something best left to an experienced auto locksmith. Unless you're familiar with all the details of the various software systems, it's very easy to make a mistake and alter settings that could damage the vehicle. The most important thing to keep in mind is that a skilled professional can assist you in avoiding these problems.
On-Board programming
If your car is old enough that it has a key, it might still come with a key made of metal that you can use to open doors and turn on the ignition. Modern cars come with a transponder that must be recognized and accepted by the computer system to start. This is an extra layer of security that stops car thieves from starting a stolen car and driving away with the car. A locksmith who is certified will have the tools and software needed to program a key that can function in your car's system.
The locksmith needs to purchase a blank key that is compatible with the model and make of your vehicle.

You can also program new keys using the EEPROM. It is more complex and requires a thorough understanding of electronic systems. It's best to leave it to a professional with expertise with these systems.
Locksmiths can program a key quickly using onboard programming. It can take as little as one minute if everything is done correctly. If the key isn't in the correct situation or the procedure is not strictly followed, it could take as long as a half hour.
There are many different key programmer scanners that can be used with different models and makes of vehicles. The Smart Pro and the Autel IM608 Pro are both well-liked by locksmiths due to the fact that they cover a wide range of automobile models. However, no system can be programmed for every vehicle on the market. In addition, these machines are expensive. It is a good idea to purchase a computer that will get regular updates as the manufacturer releases new technologies. In the event that your machine is not updated, it will become obsolete quickly.
