Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Based on the model and manufacturer, the process may be as simple as using an additional key to program the onboard computer or as complex as OBD2 programming or EEPROM.
Most US and Asian car makers use the same programming protocols as auto tool makers so that they can develop hardware and software for locksmiths in the automotive industry to use.
Transponder Chips
Transponder chips are used in many newer cars to prevent car theft. These are microchips in the form of computers which emit radio signals of low-level. The microchips are equipped with a unique serial number which authenticates your key whenever you connect it to the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down. This technology has been an incredible success in preventing auto theft. This technology has also saved car owners a great deal of money by not having to replace their vehicles.
The basic concept behind the transponder system is to make it impossible for thieves to open the doors of your vehicle without a valid key. In the past car thieves would use a flat screwdriver to force the ignition switch of your vehicle into the "on" mode or even wire it hot to get around the system. Transponder chips have drastically reduced the number of thefts.
When you insert the transponder keys into the ignition, the signal is picked up by an antenna that is hidden within the barrel. This antenna is programmed so that it can detect the particular frequency of the chip inside the key. The car's onboard computer will then detect that the key is legitimate and allow the fuel to flow, then power up the starter, or even begin it.
Some vehicles only recognize a certain type of transponder chips according to the manufacturer. It is therefore essential that your locksmith for cars is equipped with the right equipment to program your car's keys and remotes.
A reputable locksmith for automotive needs to have an instrument for programming keys for multiple vehicles that works with different car manufacturers and models. This is a much cheaper option than buying separate tools for each type of vehicle. There are also specially-designed automotive key programmer devices that are only suitable for specific brands of vehicles, but these are less frequently used. The best automotive locksmiths will have the appropriate tools to work on any type of vehicle, so ensure you choose a reputable business with these kinds of tools.
Key FOBs
As the name suggests, key FOBs house the transponder chips that can be programmed to enable your vehicle to identify and unlock the doors or start the engine using a push button ignition. They also have buttons that you can push to activate features such as door locks, trunk release or fuel flap control. Some fobs have additional functions that can be controlled by the push of a button like a "smart" key fob that lets you summon your car to parking spots that are tight similar to the Genesis GV60 or Tesla. Tesla or Genesis GV60.
While some replacement key fobs can be programmed by you with the aid of a user's guide however, you'll typically require an auto locksmith to get a new one programmed if yours stops functioning. This is because a professional locksmith has the right equipment and access to the tools for programming needed to connect your car's computer through the on-board diagnostics (OBD) port beneath the steering wheel.
The majority of key fobs come with security features that make it more difficult for criminals to clone and replicate the signals they transmit. Certain key fobs feature pseudo-random code generators that generate a unique unlock programming car key code each time you press the button. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.
In most cases, you can purchase a replacement key fob from the dealer or from another retailer and then have it programmed by your automotive locksmith to work with your particular vehicle. This is because the majority of major US and Asian automakers share their key-fob programming protocols with the third-party firms who produce the tools used by locksmiths for programming their customers' keys.
Certain key fobs from the aftermarket may be marketed as compatible with any vehicle. However, professional locksmiths advise against using them since they are likely to work poorly or not work at all. They suggest buying fobs 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 expensive repairs or replacing the fobs.
Tools for programming vehicles used by manufacturers
The automotive industry has made huge advances in the last couple of decades. Today's cars are computer-driven. One key element of this technology is a transponder chip that needs to be programmed to the vehicle by a locksmith or dealer/mechanic in order to function. Key fobs are fitted with security features that prevent hot-wiring like in a film. The car will not start without the correct keys.
Key fobs are more complicated than a mechanical keys, which is why you'll typically find them in the hands of a reputable, professional auto locksmith. 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 the car key fobs utilize a specific software system to connect to the car's onboard computer. The software blocks unauthorized access by only permitting the key to function if it has been programmed to that specific car. This means that if you get your keys replaced, you'll have to have the new key fob programmed to the car in order for it to work.
The most common method to do this is by using an auto key programming tool that is compatible with the model of the vehicle. This tool permits a locksmith to connect to the OBD port in the vehicle, and then enter the programming mode. The key programming tool can be a simple handheld device or a high-end one that can do many things beyond just key programming (like reading and cloning the Eeprom files within the ECU).
Some people may try to program their keys by themselves using these tools. However, this is best left to a professional auto locksmith. It's easy to make a mistake with the software systems if you don't understand the nuances. This could result in damage. It's important to remember that a knowledgeable professional can help you avoid these problems.
On-Board Programming
If your vehicle is older than you that you'll have a traditional metal key to open the doors and turn on the ignition. Modern cars have transponders that need to be acknowledged and accepted by the computer system in order to start. This adds an extra layer of protection that can stop car thieves from starting a car stolen and then driving off with it. A licensed locksmith will have the right tools and software to program a new key that works with your car's security system.

Once your locksmith has the key, he'll connect the programming scanner to the diagnostic port of your vehicle. This will put the car in a special programming mode, which allows locksmiths to add the key to the system.
The key scanner is programmed to communicate with the computer in the vehicle to send the code. The computer will be able to recognize the code and add it to the list of approved keys. 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 complex and requires a thorough understanding of how electronic systems operate. It is best to delegate it to a professional with experience with these systems.
Onboard programming is the quickest way for a locksmith to program a new key. If everything is done correctly it could take as little as one minute. However, if the key isn't in the correct state or the procedure is not strictly followed, it could take up to an 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 broad range of vehicle models. There is no system that can program every vehicle. These devices are also expensive. It's a good idea purchase a computer that is updated regularly when the manufacturer introduces new technologies. Your programming machine will quickly become obsolete if you do not do this.
