Automotive Locksmith Key Programming
Most modern-day cars require some kind of key programming. Depending on the model and manufacturer the procedure could be as simple as using an additional key to program the onboard computer, or as complicated as OBD2 programming or EEPROM.
Most US and Asian automakers share their programming protocol with auto tool manufacturers, so they can create hardware or software for automotive locksmiths.
Transponder Chips
Transponder chips are used in a variety of newer vehicles to guard against theft of vehicles. These are small computer microchips which emit radio signals of low-level. They have an unique serial number that authenticates your key whenever you insert it into the ignition barrel. If your vehicle isn't able to recognize the signal and the engine is shut down. This technology has proven to be an enormous success in preventing car theft. It also saves many car owners a significant amount of money as they don't have to replace their cars.
The basic concept behind the transponder system is to make it difficult for thieves to get into your vehicle without a valid key. In the past car thieves used an ordinary screwdriver to force the ignition switch in your car into "on" mode, or hot-wire it to get around the system. Transponder chips have dramatically reduced these types of thefts.
When programming car key place the transponder key in the ignition, the signal is picked up by an antenna hidden around the barrel. This antenna is programmed to detect the particular frequency of the chip within the key. The car's computer onboard will recognise that the key is valid and allow fuel to flow, turn up the starter, or even begin it.
Depending on the manufacturer certain vehicles can only accept a specific type of transponder chip. This is why it's essential to ensure that your automotive locksmith has the right equipment to program your car's key and fobs correctly.
A good automotive locksmith should have a multi-vehicle key programming device that works with different models and car brands. This is a less expensive solution than buying individual tools for every brand of vehicle. These aren't as popular but there are automotive key programmers that can only work on a specific type of vehicle. 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

They also have buttons that you can press to activate features like door locks, trunk release or control of the fuel flap. Some fobs can be controlled with the press of buttons. For example an "smart key" that lets you call your car into tight parking spaces, like the Genesis GV60, Tesla or Genesis GV60.
You can program spare key fobs by yourself with the help from the user guide, however you'll need to call an automotive locksmith if the one you have has stopped functioning. A professional is better equipped to connect the computer of your vehicle via the OBD port on the steering wheel.
The majority of key fobs come with security features that make it more difficult for criminals to clone and replicate the signals they transmit. They include pseudo-random generators that generate a new unlock code each time you press the key fob's button. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In most instances you can purchase a replacement key fob from the dealer or other retailer and then have it programmed by your locksmith in your car to be compatible with your particular vehicle. This is because the majority of major US and Asian automakers share their key-fob programming protocols with the third-party companies 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, locksmiths for automotive advise against using them since they're more likely to perform poorly or even not even work at all. Instead, they suggest buying fobs that are specifically made for your vehicle, so that you can be certain they'll work properly and are 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.
Tool for programming the vehicle manufacturers
The automobile industry has made significant advancements in the past few decades. Nowadays, cars are computer-driven. One of the most important components of this technology is a transponder chip which requires to be programmed to the vehicle by a locksmith or dealer/mechanic in order to function. 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.
Key fobs are a little more complex than a traditional mechanical key. This is why they are placed in the hands of experienced, professional auto locksmiths. The cost of a key fob may differ based on the vehicle model and the type of key, but they typically run between $85 and $400. This includes the labor cost to program the keyfob and any replacement parts.
These car key fobs are more complex due to the fact that they use software that interacts with the onboard computer of the car. The software blocks access to unauthorised users by only allowing keys that have been programmed for a specific car to function. This means that if you need your keys replaced, you'll have to have the new key fob programmed to the car for it to function.
This is done by using a programing tool for car keys that is compatible with the vehicle's brand. This tool permits a locksmith to connect to the OBD port on the vehicle and then enter programming mode. The key programming device can be a handheld device that is cheap or extravagant and can do more than just programming keys (like reading the eeprom file inside the ECU).
Although some people might attempt to program their own keys with these tools, this is an activity best left to a professional auto locksmith. It's easy to make mistakes with the software systems if you aren't aware of the nuances. This could lead to damage. It's important to remember that a professional with experience will help you avoid these issues.
On-Board Programming
If your vehicle is of a certain age, you'll still have a key from the past to use to unlock the doors and turn over the ignition. However, modern cars are equipped with transponder chips that need to be recognized by the car's computer system in order to start. This adds another security measure to prevent thieves from stealing the car and then driving off with a stolen vehicle. A locksmith who is certified will have the tools and software needed to program a key that will be compatible with your car's security system.

Once your locksmith has the key, he'll connect the programming scanner to the diagnostic port of your vehicle. This will put your car into the mode of programming that allows the locksmith to add a new key to the system.
The key scanner is programmed to communicate with the computer in the car to send an electronic code. The computer will detect this code and add it to the list of keys that are approved. In certain instances the scanner may also be able to erase keys that are stolen or lost from the system.

You can also program new keys with EEPROM. It is more complex and requires a deep understanding of electronic systems. It is best to leave it to a professional who has experience with these systems.
Locksmiths can program a key quickly by using onboard programming. If everything is done correctly it could take as little as one minute. If the key isn't placed in the right state or the procedure isn't strictly followed, it could take up to a half hour.
There are numerous key programmer scanners available that work with various car models and makes. Both the Smart Pro and Autel IM608 Pro have become very popular with locksmiths due their wide range of vehicle models. No system can program every vehicle. Furthermore, these systems are expensive. It is recommended to purchase an instrument that receives regular updates from the manufacturer when new technologies are introduced. Your machine for programming will quickly become outdated if you don't do this.
