Automotive Locksmith Key Programming
Modern cars need some form of key programming. Depending on the car's maker and model, the process can be as easy as onboard programming using an extra working key or as complicated as EEPROM or OBD2 programming.
Most US and Asian automobile manufacturers have programming protocols that they share with auto tool makers in order to create tools and hardware for locksmiths working in automotive vehicles.
Transponder Chips
The majority of newer cars have what are called transponder chips to prevent car theft. These are tiny computer microchips that emit radio waves of low-level. The microchips have an unique serial number that authenticates your keys when you plug it into the ignition barrel. If your vehicle isn't able to recognize the signal and the engine is shut down. This technology has proved to be an incredible success in preventing auto theft. This technology has also helped car owners save a huge deal of money since they don't have to buy new vehicles.
The principle behind the transponder system is to make it difficult for thieves to start your vehicle without a valid key. In the past, thieves used a flat screwdriver to force the ignition switch in your car to go into "on" mode or even hot-wire it to bypass the system. Transponder chips have dramatically reduced these types of thefts.
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 with the frequency of the chip in the key. The computer onboard of the car will recognize the key as being valid and allow fuel flow and power the starter to begin the engine.
Certain vehicles only recognize a certain type of transponder chips, depending on the manufacturer. This is why it is essential to ensure that your automotive locksmith is equipped to program your car's key and fobs properly.

Be sure to choose a reliable company that is equipped with this type of equipment.
Key FOBs

A professional is better equipped to connect your computer to the car via the OBD port located under the steering wheel.
The majority of key fobs are equipped with security features to make it difficult for attackers to clone and replicate the signals that they transmit. These include pseudo-random sequence generators that generate an entirely new unlock code every time you press the button on your key fob. This is to prevent attackers from capturing and playing back the unlock signal in order to gain access to your car.
In most instances, you can purchase a replacement key fob from the dealer or other retailer and have it programmed by a locksmith for your vehicle to work with your specific vehicle.

This includes the cost of labor to program the key fob as well as the cost of any needed replacement parts.
Car key fobs are more complicated because they utilize a software system that works with the computer onboard of the car. The software prevents unauthorised access by only permitting keys that have been programmed for a specific vehicle to work. If you change your keys, you will have to program the new key fob to the car to allow it to work.
The most common way to do this is by using the car key programming tool that is compatible with the model of the vehicle. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) within the vehicle and then enter a programming mode. Key programming tools can either be an inexpensive handheld device or a high-end one that can do many things beyond key programming (like reading and cloning the Eeprom files within the ECU).
Some people may try to program their keys themselves using these tools. However, this is best left to an expert auto locksmith. Unless you're familiar with all the details of the various software systems, it's easy to accidentally alter settings that could cause damage to the vehicle.

The EEPROM programming method is a different one that can be used to program new car keys. It is more complicated and requires a thorough understanding of electronic systems. It's best to leave it to a professional who has expertise with these systems.
Onboard programming is the quickest way for a locksmith to program an entirely new key. When everything is done correctly it can take as little as one minute. If the key isn't placed in the right situation or the procedure is not strictly followed, it could take up to a half hour.
There are many key programmer scanners on the market that can be used with different car models and makes. Both the Smart Pro and Autel IM608 Pro are very popular among locksmiths due to their wide selection of vehicle models. No system can program every vehicle. Additionally, these devices cost a lot. It's a good idea to purchase a programer that will get regular updates as the manufacturer releases new technologies.
