Automotive Locksmith Key Programming
Modern cars need some form of key programming. Depending on the model and manufacturer the procedure could be as simple as using a spare key to programme the computer onboard, or as complicated as OBD2 programming or EEPROM.
The majority of US and Asian auto manufacturers have a programming protocol that they share with auto tool makers, so they can develop hardware or software for automotive locksmiths.
Transponder Chips
Transponder chips are in a lot of modern cars to guard against theft of vehicles. These are tiny computer microchips which emit low-level radio waves. They have a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your car doesn't recognise the signal it will stop the engine. This technology has been an enormous success in preventing car theft. It has also saved many car owners a significant amount of money as they don't have to replace their vehicles.
The fundamental idea behind the transponder system is to make it difficult for thieves to start your vehicle without a valid key. In the past, car thieves would simply force your ignition switch to the "on" position with an ordinary screwdriver or use hot wires to disable the system altogether. Transponder chips have drastically reduced these types of thefts.
When you insert a transponder keys into the ignition, it will transmit an electrical signal that is picked up by a hidden antenna that is positioned around the barrel of the ignition. This antenna is programmed to detect the particular frequency of the chip within the key. The car's onboard computer will then recognize that the key is genuine and allow the fuel to flow, then power up the starter, or even start it.
Some vehicles only recognize specific type of transponder chip, depending on the manufacturer. This is why it's important to ensure that your automotive locksmith has the appropriate equipment to program your car's key and fobs correctly.
A reputable locksmith for cars should have a multi-vehicle key programming device that is compatible with different models and manufacturers of cars. This is a more cost-effective option than purchasing specific tools for each type of vehicle. They are not as common, but there are specialised automotive key programming tools that can only work on a specific type of vehicle. The best automotive locksmiths have the tools to work on any vehicle. Be sure to choose a reliable company that is equipped with this type of equipment.
Key FOBs
As the name implies, key FOBs are home to the transponder chips programmable that allow 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. Some fobs have additional functions that can be controlled by the button presses for example, a "smart" key fob that lets you summon your car to parking spots that are tight, like you would with the Genesis GV60, Tesla or Genesis GV60.
While some replacement key fobs can be programmed by you with the help of a user manual, you'll often need an automotive locksmith to get a new one programmed if yours stops working. This is because a professional locksmith has the specialized equipment and access to the tools for programming needed to connect your car's computer to the on-board diagnostics (OBD) port that is located under the steering wheel.
The majority of key fobs come with security features that make it harder for attackers clone and replicate the signals that they transmit. They include pseudo-random sequence generators that generate a fresh unlock code every time you press the button on the key fob. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In many cases, you can purchase an additional key fob at the dealership or another retailer and then have it programmed by your automotive locksmith to be compatible with your specific vehicle. This is because the majority of major US and Asian automakers share their key-fob programming protocols with the third-party firms who make the tools used by locksmiths for programming their customers' keys.

Instead, they suggest purchasing fobs that are specifically made for your vehicle so that you can be certain they'll function properly and be less susceptible to issues such as interfering or incompatibility. This will save money over time by avoiding costly repairs or replacements of your fobs.
Vehicle Manufacturers' Programming Tools
The automotive industry has progressed a lot and today's vehicles need computer technology in order to function. A transponder chip is an important part of this technology. It has to be programmed by a locksmith, mechanic or dealer to work. These key fobs have built-in security features that prevent hot-wiring (like in a film) and the car won't start without the proper key.
These key fobs can be somewhat more complicated than a standard mechanical key. This is why they are placed in the hands of experienced professional auto locksmiths. The cost of a key fob will vary depending on the car model and the key type, but they typically run between $85 and $400. This includes the labor cost to program the keyfob as well as any replacement parts.
These car key fobs are more complicated because they use a software system that works with the computer onboard of the car. The software prevents unauthorised access by only allowing keys programmed for a specific vehicle to work. If you replace your keys, you will need to program the new key fob in the car to allow it to function.
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 allows the locksmith to connect to the onboard diagnostics port (OBD) within the vehicle and then enter a programming mode. The key programming device could be a handheld device that's inexpensive or one that is extravagant and can do more than just program keys (like reading the eeprom files in the ECU).
Some people might try to program their keys themselves using these tools. However it's best to leave this task to an expert auto locksmith.

You can also program new keys using the EEPROM. It is more complex and requires a deep understanding of how electronic systems function. This is why it's best left to a professional that has extensive experience working with these kinds of systems.
Onboard programming is the fastest way for a locksmith to program a new key. It can take as little as one minute if everything is executed correctly. However, if the key isn't placed in the correct state or the procedure isn't adhered to, it could take as long as a half hour.
There are numerous key programmer scanners on the market that work with various vehicle models and brands. Both the Smart Pro and Autel IM608 Pro have become extremely popular with locksmiths due to their wide range of vehicle models. There is no system that can program every vehicle.
