Modern vehicles require some form of key programming. Depending on the vehicle's make and model, the procedure can be as easy as onboard programming with a spare key that works or as complex as OBD2 or EEPROM programming.
The majority of US and Asian car manufacturers use the same programming protocols as auto tool makers so that they can develop hardware and software for automotive locksmiths to use.
Transponder Chips
Most modern cars are equipped with what are called transponder chips in order to prevent theft. These are microchips in the form of computers that emit radio signals at a low level. The microchips are equipped with a unique serial number which authenticates your keys when you insert it into the ignition barrel. If your vehicle doesn't recognize the signal it will shut down the engine. This technology has proven to be an enormous success in preventing theft of cars. This technology has also helped car owners save a huge deal of money as they do not have to purchase new cars.
The principle of the transponder system is to make it impossible for thieves to open the doors of your vehicle without the correct key. In the past, car thieves would force your ignition switch to the "on" position with a flat screwdriver or even use hot wires to disable the system completely. These kinds of thefts have been dramatically reduced thanks to the introduction of the transponder chip.
When you insert the transponder key into the ignition, the signal is picked up by an antenna that is concealed around the barrel. This antenna is programmed so that it can detect the particular frequency of the chip within the key. The car's onboard computer will then recognize that the key is valid and allow fuel to flow, turn the starter or start it.
Depending on the manufacturer, some vehicles will only recognise a specific type of transponder chip. It is therefore essential that your locksmith for cars is equipped with the correct equipment to program your car's keys and remotes.
A reputable locksmith for cars should have an instrument for programming keys for multiple vehicles that works with different models and manufacturers of cars. This is a cheaper alternative than buying specific tools for each model of vehicle. There are also specialised key programming devices for automotive that can only be used on specific models of vehicles however they are not as popular. The best automotive locksmiths are equipped to work on any vehicle. Make sure you choose an established company that has this kind of equipment.
Key FOBs
As the name suggests, key FOBs are home to the programmable transponder chips that enable your car to recognize and unlock the doors or start the engine with a push-button ignition. You can also press buttons to trigger features such as door locks, trunk releases or fuel flap controls. Some fobs also have additional functions that can be controlled by the button presses like the "smart" key fob that lets you bring your car into tight parking spots similar to the Genesis GV60 or Tesla. Tesla or Genesis GV60.
You can program replacement key fobs yourself using the assistance of an instruction manual, however you'll need to contact an automotive locksmith if yours isn't functioning. This is because a professional has the specialized equipment and access to the programming tools needed to connect your car's computer to the OBD (OBD) port located beneath the steering wheel.
The majority of key fobs today include security features that make it difficult for attackers to clone or replicate the signals they transmit. Certain key fobs feature pseudo-random code generators, which generate a unique unlock code each time you press the button. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.
In certain instances, you can buy a replacement keyfob from an auto dealer or other retailer. Your locksmith at your auto will then program it to work with your vehicle. This is because the majority of major US and Asian auto manufacturers use the same key-fob programming protocol with third-party companies that create the tools used by locksmiths for programming their customers' keys.
Certain aftermarket key fobs can be marketed as being compatible with all vehicles. However, locksmiths for automotive recommend against using them because they are likely to work poorly or not at all. Instead, they recommend purchasing fobs designed specifically for your vehicle, so that you can be sure they'll function correctly and are less prone to issues such as interfering or not working. This will save money over time by avoiding costly repairs or replacements of your fobs.
Tools for programming vehicles used by manufacturers
Automotive technology has progressed a lot and today's vehicles need computers to function. Transponder chips are an essential part of this technology.

The car won't start without the correct keys.
Key fobs are a little more complex than a conventional mechanical key. This is why they are in the hands of seasoned, professional auto locksmiths. The cost of the car key fob is dependent on the type and model of key, but is generally between $85 to $400. This includes the cost of labor to program the keyfob as well as any replacement parts.
The car key fobs are more complicated due to the fact that they use an operating system that communicates with the computer onboard of the car. The software blocks access to unauthorized users by only permitting the key to function if it has been programmed to the car in question. If you change your keys, you'll have to program the new key fob into the car for it to function.
The most popular method to accomplish this is using an auto key programming tool that is compatible with the brand of the vehicle. This tool lets the locksmith connect to the OBD port (OBD) within the vehicle and then enter an programming mode. The key programming tool could be a handheld device that is inexpensive device or a more expensive one that can do various things beyond key programming (like reading and cloning the EEEPROM files in the ECU).
Although some people might attempt to program their own keys with these tools, this is an activity best left to an experienced auto locksmith. If you're not familiar with the details of the various software systems, it's possible to make a mistake and alter settings that could cause damage to the vehicle.

On-Board Programming
If your car is old enough that it has a key, it might still come with a metal key that can be used to open doors and turn off the ignition. Modern cars come with transponders that need to be acknowledged and accepted by the computer system to start. This is an additional layer of protection that can stop car thieves from starting a car stolen and then driving off with it. A locksmith who is certified will have the necessary tools and software to program a new key that is compatible with your car's security system.
First, your locksmith will need to get a blank key that is compatible with the make and model of your vehicle. Once the key is in hand, your locksmith will link the programming scanner to your car's diagnostic port. This will put the car into a special programing mode, which allows the locksmiths to add the key to the system.
To accomplish this, the key programmer scanner will communicate with the car's computer system to transmit a specific code. The computer will recognize the code and add it to the list of keys approved by. In some instances, the scanner will also be able to delete lost or stolen keys from the system.
Programming EEPROM is another method that can be used to program new car keys. It is more complicated and requires a deep understanding of electronic systems. This is why it's best left to a professional who has extensive expertise working on these types of systems.
