Automotive Locksmith Key Programming
The majority of modern cars require some type of key programming. Depending on the model and make, the process may be as simple as using an extra key to program the onboard computer, or as complex as EEPROM or OBD2 programming.
The majority of US and Asian automobile manufacturers have programming protocols that they share with auto tool manufacturers so that they can develop hardware and software for locksmiths in the automotive industry to use.
Transponder Chips
Transponder chips are found in a lot of modern cars to stop theft of cars. 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 when you connect it to the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down. This technology has proved to be an immense success in stopping auto theft. It also saves many car owners a significant amount of money since they don't have to buy new their vehicles.
The fundamental idea behind the transponder system is to make it difficult for thieves to get into your car without a key. In the past, car thieves would use an ordinary screwdriver to force the ignition switch of your car into "on" mode, or hot-wire it to bypass the system. Transponder chips have drastically reduced the number of thefts.
When you insert a transponder keys into the ignition, it transmits the signal which is picked up by a hidden antenna that is positioned around the barrel of the ignition. The antenna is programmed to detect the particular frequency of the chip inside the key. The onboard computer in the car will then recognise the key as valid and allow fuel flow and power the starter to start the engine.
Depending on the manufacturer, certain vehicles can only accept the specific type of transponder chip. It is therefore important that your locksmith for cars is equipped with the right equipment to program your car's keys and remotes.
A good automotive locksmith will utilize a multi-vehicle programmable device which can be used on many different models and brands of cars. This is a far cheaper alternative than buying individual tools for each brand of vehicle. These aren't as popular but there are automotive key programmers that are able to only work on a particular model of vehicle. The top automotive locksmiths have the tools needed to work on any vehicle. Make sure you select a reliable company that is equipped with this type of equipment.
Key FOBs

There are also buttons that you can press to trigger features such as door locks, trunk release or fuel flap control. Some fobs can be controlled by pressing buttons. For example the "smart key" that lets you call your car to parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.
You can program replacement key fobs yourself with the assistance of the user guide, however you'll need to call an automotive locksmith if the one you have isn't working.

The majority of key fobs come with security features to make it more difficult for criminals to clone and replicate the signals they transmit. They include pseudo-random generators that generate a fresh unlock code each time you press the button on the key fob. This stops attackers from recording and replaying the unlock signal to gain access to your car.
In certain instances, you can buy the replacement keyfob at an authorized dealer or another retailer. The locksmith you choose to use will then program it to work with your vehicle. This is because the majority of major US and Asian automakers share their key-fob programming protocols with the third-party firms who produce the tools used by locksmiths for programming their customers' keys.
While some aftermarket key fobs are marketed as being compatible with all vehicles however, the majority of locksmiths for automotive do not recommend using them because they are likely to function poorly or not at all. Instead, they recommend purchasing fobs that are specifically made for your specific vehicle so that you are certain they'll work properly and are less prone to issues such as interference or incompatibility. This will save you money in the end by avoiding costly repairs or replacing your fobs.
Vehicle Manufacturers' Programming Tool
Automotive technologies have advanced considerably, and today's vehicles require computer technology to function. Transponder chips are an important part of this technology. It must be programmed by a locksmith mechanic, or dealer to work.

The cost of the car key fob can vary depending on the type and model of key, but it is generally between $85 and $400. This includes the labor to program the key fob, as well as the costs for any required replacement parts.
To make the process more difficult the car key fobs make use of a special software to communicate with the car's onboard computer. The software prevents unauthorised access by only allowing keys that have been programmed for a specific car to work. This means that if your keys replaced, you'll need have the new key fob programed to the car for it to work.
The most common method to do this is by 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) within the vehicle and then enter the programming mode. The key programming device could be a handheld device that's cheap or sophisticated and capable of doing more than just program keys (like reading the eeprom file in the ECU).
Although some people might attempt to program their own keys using these tools, it's an activity best left to an experienced auto locksmith. If you're not aware of all the aspects of the various software systems, it's very easy to make a mistake and alter settings that could cause damage to the vehicle.

To do this, the key programming scanner will communicate with the car's computer and send a particular code. The computer will recognize the code and add it to the list of keys that are approved. In some instances the scanner will also remove keys that have been stolen or lost.
You can also program new keys using EEPROM. It is more complicated and requires a thorough understanding of how electronic systems work. This is why it should be left to a professional that has a lot of experience working on these types of systems.
Onboard programming is the fastest method for locksmiths to program a new key. If everything is done properly it could take just one minute. If the key isn't placed in the correct state or the procedure is not adhered to, it could take as long as a half hour.
There are numerous key programmer scanners available that can be used with different car models and makes. The Smart Pro and the Autel IM608 Pro are both extremely popular with locksmiths since they support a broad range of vehicle models. However, neither will be able to program every single vehicle that exists. Additionally, these devices cost a lot. It's a good idea to purchase a programer that will get regular updates as the manufacturer develops new technologies. Your programming machine will quickly become outdated if you don't take this step.
