Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Based on the model and make the procedure could be as simple as using a spare key to program the onboard computer or as complex as OBD2 programming or EEPROM.
The majority of US and Asian auto manufacturers share their programming protocol with auto tool makers, so they can develop hardware or software for automotive locksmiths.
Transponder Chips
Most modern cars are equipped with transponder chips in order to prevent theft. These are tiny computer microchips which emit radio waves of low-level. They have an unique serial number that authenticates your keys when you connect it to the ignition barrel. If your vehicle doesn't recognize the signal it will shut down the engine. This technology has been extremely successful in preventing theft of cars. It has also saved many car owners a significant amount of money as they don't need to replace their vehicles.
The transponder system's basic idea is to make it impossible for thieves to start your vehicle without the correct key.

Transponder chips have drastically decreased the likelihood of theft.
When you insert a transponder keys into the ignition, it will transmit the signal which is received by a hidden antenna circling the barrel of the ignition. This antenna is programmed so that it can detect the particular frequency of the chip inside the key. The car's computer onboard will recognize that the key is genuine and allow the fuel to flow, then power the starter or begin it.
Some vehicles only recognize certain type of transponder chips, depending on the manufacturer. It is therefore important that your locksmith for cars is equipped with the correct equipment to program your keys and remotes for your vehicle.

For instance an "smart key" which allows you to summon your car to tight parking spaces, such as the Genesis GV60, Tesla or Genesis GV60.
You can program spare key fobs by yourself with the help of the user guide, however you'll need to call an automotive locksmith if yours has stopped working.

The majority of key fobs come with security features that make it difficult for attackers to clone and replicate the signals that they transmit. These include pseudo-random sequence 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.

Instead, they suggest purchasing fobs designed specifically for your specific vehicle so that you are certain they'll function correctly and are less susceptible to issues like interfering or not working. This will save you money in the end by avoiding expensive repairs or replacing your fobs.
Vehicle Manufacturers' Programming Tools
The automotive industry has made huge advancements in the past few decades. Nowadays, cars are computer-driven. One of the key components of this technology is a transponder chip that needs to be programmed to the vehicle by an expert locksmith or dealer/mechanic in order to function. Key fobs come with built-in security features that will prevent hot-wiring (like in a film) and the car won't start without the proper key.
Key fobs are a little more complex than a standard mechanical key. This is why they are handled by experienced, professional auto locksmiths. The cost of a car key fob varies dependent on the type and model of key, but is generally between $85 and $400. This includes labor costs to program the keyfob as well as any replacement parts.
To make the process more complicated to make the process more complicated, these key fobs for cars make use of a special software to communicate with the car's onboard computer. The software blocks unauthorized access by only permitting the key to function only if it's programmed for the specific car. This means that if you need your keys replaced, you'll need have the new key fob programmed to the car in order to function.
The most common method to accomplish this is using the car key programming tool that is compatible with the model of the vehicle. This tool allows locksmiths to connect to the OBD port of the vehicle and then enter programming mode. Key programming devices can be a handheld device that's cheap or fancy and can do more than just programming keys (like reading the eeprom file inside the ECU).
Some people might attempt to program their keys themselves using these tools. However it's best to leave this task to an expert auto locksmith. It's easy to make mistakes with the software systems if you don't know the intricacies. This could lead to damage. The most important thing to keep in mind is that an experienced professional can assist you in avoiding these issues.
On-Board programming
If your car is older than you that you'll have a traditional key made of metal to use to unlock the doors and turn on the ignition. Modern cars have transponders that need to be recognized and accepted by the computer system to start. This is a further security measure to prevent thieves from starting and driving away with a stolen vehicle. A locksmith certified has the tools and software required to create a key that will be compatible with your car's security system.
Your locksmith will first need to acquire a blank key that is compatible with the vehicle's model and make. Once your locksmith has the key, he'll connect the scanner for programming to the diagnostic port of your vehicle. This will place the car in a special programming mode, which allows the locksmiths to add the key to the system.
To do this, the key programming scanner will communicate with the car's computer and send a specific code. The computer will detect this code and include it into the list of approved key. In certain instances, the scanner will also be able to remove lost or stolen keys from the system.
You can also program new keys by using EEPROM. It is more complicated and requires a thorough understanding of electronic systems. This is why it's best left to a professional that has years of experience working with these kinds of systems.
Locksmiths can program keys quickly using onboard programming. It takes as little as an hour if everything is executed correctly. If the key isn't in the right condition or the procedure isn't followed exactly, the process could be as long as half an hour.
There are numerous key programmer scanners that can be used with different makes and models of vehicles. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due their broad range of vehicle models. However, neither can be programmed for every vehicle in existence. They are also expensive. It's best to purchase a programmer which will receive regular updates from the manufacturer as new technologies are released. If not, your computer will be obsolete in a short time.
