Automotive Locksmith Key Programming
Modern cars need some form of key programming. Depending on the model and manufacturer, the process may be as simple as using an extra key to program the onboard computer or as complex as EEPROM or OBD2 programming.
The majority of US and Asian automobile manufacturers have programming protocols that they share with auto tool manufacturers so that they can develop software and hardware for locksmiths in the automotive industry to use.
Transponder Chips
Most newer cars use transponder chips to prevent car theft. These are microchips in the form of computers that emit radio signals at a low level. They have a unique serial number that authenticates your key whenever you connect it to the ignition barrel. If your vehicle doesn't recognize the signal it will stop the engine. This technology has been an enormous success in preventing car theft. This technology has also saved car owners a great amount of money since they don't have to replace their vehicles.

The basic idea behind the transponder system is to make it impossible for thieves to get into your vehicle without a valid key. In the past, thieves would force your car's ignition switch into the "on" position using an ordinary screwdriver or use hot wires to disable the system completely. These types of thefts have been drastically reduced thanks to the introduction of the transponder chip.
When you insert a transponder key into the ignition, it will transmit the signal which is detected by a hidden antenna circling the barrel of the ignition. This antenna is programmed to read the specific frequency of the chip within the key. The car's computer onboard will recognize that the key is legitimate and allow fuel to flow, turn the starter or begin it.
Depending on the manufacturer, some vehicles will only recognise certain types of transponder chip. This is why it is important to ensure that your locksmith in the automotive industry is equipped to program your car's key and fobs properly.
A reputable locksmith for automotive needs to have an instrument for programming keys for multiple vehicles that is compatible with different models and manufacturers of cars. This is a less expensive solution than buying specific tools for each type of vehicle. They are not as common, but there are specialised automotive key programming tools that can only be used on a specific model of vehicle. The top automotive locksmiths have the tools needed to work on any vehicle. Make sure you choose an established company that has this type of equipment.
Key FOBs
The name implies that key FOBs are home to the transponder chips that can be programmed to allow your vehicle to recognize and open the doors, or start the engine using a push button ignition. You can also use the buttons to activate features like door locks, trunk releases or control of the fuel flap. Certain fobs can be controlled with the press of buttons. For example the "smart key" which allows you to summon your car into tight parking spaces, like the Genesis GV60 or a Tesla or Genesis GV60.
While some replacement keys can be programmed by you with the aid of a user's guide however, you'll typically require an automotive locksmith to get a new one programmed if the one you have isn't functioning. A professional is better equipped to connect your computer to the car via the OBD port under the steering wheel.
Today, most key fobs include security features that make it difficult for criminals to duplicate or duplicate the signals they transmit. reprogram car key feature pseudo-random code generators, which generate a new unlock code every time you press the button. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.
In many cases you can buy an additional key fob at the dealer or other retailer and 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 auto manufacturers use the same key-fob programming protocol with the third-party companies who create the tools used by locksmiths who program their customer's keys.
Some aftermarket key fobs may be advertised as being compatible with vehicles of all kinds. However, professional locksmiths recommend against using them because they are likely to work poorly or even not even work at all. They suggest purchasing fobs that are designed specifically for your vehicle so that they function properly and are less susceptible to issues like interference or incompatibility. This will save you money in the end by avoiding costly repairs or replacing your fobs.
Toolkits for Programming Vehicles of Manufacturers
The automotive industry has advanced considerably, and today's vehicles require computer technology to function. Transponder chips are an essential part of this technology. It must be programmed by a locksmith, mechanic or dealer to work. Key fobs come with built-in security features that will prevent hot-wiring (like in a movie) and the car will not start if you don't have the right key.
These key fobs are a bit more complex than your mechanical keys and that's why you'll typically find them in the hands of an expert professional auto locksmith. The cost of a car key fob varies dependent on the type and model of key, but is typically between $85 to $400. This includes the labor required to program the key fob as well as the cost of any needed replacement parts.
To complicate the process the car key fobs make use of a special software to work with the car's onboard computer. The software blocks access to unauthorized users by only permitting the key to function if it has been programmed to the car in question. This means that if you need your keys replaced, you'll need have the new key fob programmed to the car for it to function.
The most common method to accomplish this is using an auto key programming tool that is compatible with the brand of the vehicle. This tool allows a locksmith to connect to the OBD port on the vehicle, and then enter the programming mode. Key programming tools can be a simple handheld device or a fancy one that can perform many things beyond key programming (like reading and cloning the eeprom files in the ECU).
Some people might attempt to program their keys on their own using these tools. However, this is best left to a professional auto locksmith. Unless you're familiar with all the ins and outs of the various software systems, it's possible to accidentally change settings that could potentially damage the vehicle. It's important to keep in mind that an experienced professional will assist you in avoiding these issues.
On-Board programming
If your car is old enough, it may still come with a metal key that can be used to open doors and turn off the ignition. Modern cars come with transponders that must be recognized and accepted by the computer system in order to start. This is an additional layer of security that prevents thieves from starting and then driving off with a stolen vehicle. A locksmith certified will have the tools and software necessary to program a key that will work in your car's system.
Your locksmith will have to purchase a blank key that is compatible with your car's make and model. Once your locksmith has the key, he will connect the programming scanner to the diagnostic port of your vehicle. This will put the vehicle into the mode of programming that will allow the locksmith to add a new key into the system.
The key programmer scanner communicates with the computer in the vehicle to send the code. The computer will be able to recognize this code and add it to the list of keys that are approved. In certain situations, a scanner can also remove keys that have been stolen or lost.
Programming EEPROM is another method that can be used to program new car keys. It is more complicated and requires a thorough understanding of electronic systems. It is best to leave it to a professional with expertise with these systems.
Locksmiths can program keys quickly by using onboard programming. When everything is done correctly, it can take as little as one minute. If the key isn't in the proper state or the procedure isn't strictly followed, it could take up to a half hour.
There are a variety of key programmer scanners available that work with various car models and makes. Both the Smart Pro and Autel IM608 Pro have become extremely popular among locksmiths due to their wide selection of models for vehicles. However, neither can program every single vehicle that exists. Furthermore, these systems are expensive. It's a good idea to purchase a computer that is updated regularly as the manufacturer releases new technologies. Otherwise, your programming machine will soon become obsolete.
