Automotive Locksmith Key Programming
The majority of modern cars require some type of key programming. Based on the car's make and model, the process could be as simple as programming onboard using a spare key that works or as complex as EEPROM or OBD2 programming.
The majority of US and Asian car manufacturers have programming protocols that they share with auto tool manufacturers so that they can develop tools and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Transponder chips are used in many newer cars to prevent car theft. These are tiny computer microchips that emit radio waves of low-level. The microchips are equipped with an unique serial number that authenticates your keys when you connect it to the ignition barrel. If your car isn't able to recognize the signal, it will shut down the engine. This technology has proven to be extremely successful in preventing car theft. This technology has also saved car owners a great amount of money by not having to buy new vehicles.
The basic idea behind the transponder system is to make it difficult for thieves to start your car without the proper key. In the past, thieves would simply force your ignition switch to the "on" position with an ordinary screwdriver or make use of hot-wires to bypass the system altogether. These types of thefts have been dramatically decreased with the introduction of the transponder chip.
When you insert a transponder keys into the ignition, it transmits a signal that is received by a hidden antenna around the barrel of the ignition. program car key is programmed with the frequency of the chip in the key. The onboard computer in the car will then recognize the key as being valid and will allow fuel flow, power the starter or start the engine.
Some vehicles only recognize certain type of transponder chip, depending on the manufacturer. This is why it is crucial to make sure that your locksmith in the automotive industry is equipped to program your car's keys and fobs correctly.
A good automotive locksmith will utilize a multi-vehicle programmable device which can be used on a variety of different models and brands of cars. This is a far cheaper option than buying separate tools for each type of vehicle. These aren't as popular, but there are specialised automotive key programmers that can only work on a specific type of vehicle. The most reliable automotive locksmiths will have the right tools to work on any type of vehicle, so be sure you find a reputable company that offers these types of tools.
Key FOBs
As the name implies, key FOBs house the transponder chips that can be programmed to allow your car to recognize and unlock the doors, or start the engine using a push button ignition. There are also buttons that you can push to activate features like trunk release, door locks or fuel flap control. Some fobs can be controlled with the press of buttons. For instance the "smart key" that allows you summon your car into tight parking spaces, like the Genesis GV60, Tesla or Genesis GV60.
While some replacement key fobs can be programmed by you using the assistance of a user's manual but you'll usually need an automotive locksmith to get a new one programmed if yours stops working. This is because a professional has the equipment that is specialized and access to the tools for programming needed to connect your car's computer through the on-board diagnostics (OBD) port located beneath the steering wheel.
The majority of key fobs come with security features to make it difficult for attackers to duplicate and copy the signals they transmit. These include pseudo-random sequence generators that generate a new unlock code each time you press the button on your key fob. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In certain instances you can purchase a replacement keyfob from an auto dealer or other retailer. The locksmith you choose to use will then program it to work with your car. This is because the majority of major US and Asian automakers have key-fob programming protocols with third-party companies that make the tools used by locksmiths who program their customer's keys.

Although some key fobs from the aftermarket are marketed as being compatible with all vehicles however, the majority of locksmiths for automotive don't recommend using them since they are likely to function poorly or not at all. Instead, they suggest buying fobs designed specifically for your vehicle so that you are certain they'll function properly and be less prone to issues like interference or incompatibility. This will save you money in the end by avoiding expensive repairs or replacing the fobs.
Tools for programming vehicles used by manufacturers
Automotive technologies have advanced considerably, and today's vehicles require computer technology to function. One key element 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. These key fobs are equipped with security features to prevent hot-wiring like in a movie. The car will not start if the keys are not correct.
Key fobs are more complicated than a traditional mechanical keys and are the reason you'll usually find them in the hands of a skilled, professional auto locksmith. The cost of the car key fob is according to the model and type of key, but is usually between $85 and $400. This includes the cost of labor to program the key fob as well as the cost of any needed replacement parts.
To make the process more complicated the car key fobs use a special software system to work with the car's onboard computer. The software prevents unauthorized access by allowing the key to function if it has been programmed to that specific car. This means that if your keys replaced, you'll need to have the new key fob programmed to the car in order to function.
This is accomplished using a programing tool for keys for cars that are compatible with the vehicle's brand. This tool allows the locksmith to connect to the OBD port (OBD) in the vehicle and then enter an programming mode. Key programming devices can be an handheld device that is inexpensive or one that is extravagant and can do more than just program keys (like reading the eeprom files in the ECU).
While some may try to program their own keys using these tools, it's a job best left to an experienced auto locksmith. Unless you're familiar with all the details of the various software systems, it's easy to accidentally change settings that could damage the vehicle. 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 old enough, it may still come with a key made of steel that can be used to open doors and turn on the ignition. However, modern vehicles are equipped with a transponder chip that must be recognized by the computer system to allow it to start. This adds another security measure to prevent thieves from stealing the car and then driving off with a stolen car. A locksmith certified will have the tools and software required to program a key that can be compatible with your car's security system.
Your locksmith will have to acquire a blank key that is compatible with your car's model and make. Once the key is in hand, your locksmith will link the scanner for programming to the diagnostic port of your car. This will place the car into a special programming mode that allows the locksmith to add a new key into the system.
To do this, the key programmer scanner will communicate with the car's computer to send a specific code. The computer will be able to recognize the code and add it to the list of keys approved by. In some cases, the scanner will also be able to erase keys that are stolen or lost from the system.
EEPROM programming is another method that can be used to program new car keys. It is more complex and requires a thorough understanding of how electronic systems operate. This is why it's best left to a professional who has years of experience working on these types of systems.
Onboard programming is the most efficient method for locksmiths to program an entirely new key. If everything is done properly it can take just one minute. If the key isn't in right condition or the procedure is not adhered to, it could take up to an hour.
There are numerous key programmer scanners that support different models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro have become extremely popular with locksmiths due their broad range of models for vehicles. However, no system will be able to program every vehicle in existence. These machines are also quite expensive. It's a good idea buy a programmer that is updated regularly when the manufacturer introduces new technologies. If not, your computer will become obsolete quickly.
