What NOT To Do Within The Automotive Locksmith Key Programming Industry
Automotive Locksmith Key Programming

The majority of modern cars require some form of key programming. Depending on the car's maker and model, the process can be as easy as programming onboard using a spare key that works or as complex as EEPROM or OBD2 programming.

Most US and Asian car makers share their programming protocols with auto tool makers to allow them to develop tools and hardware for automotive locksmiths to use.

Transponder Chips

Most modern cars are equipped with what are called transponder chips to prevent car theft. These are microchips in the form of computers which emit radio signals of low-level. The microchips have an unique serial number that authenticates your keys when you insert it into the ignition barrel. If your car isn't able to recognize the signal, it will shut down the engine. This technology has proved to be an enormous success in preventing auto theft. This technology has also helped car owners save a good amount of money since they don't have to replace their vehicles.

The principle of the transponder system is to make it hard for thieves to start your car without the right key. In the past, car thieves would simply force the ignition switch of your car into the "on" position using a flat screwdriver or even use hot wires to disable the system completely. Transponder chips have drastically decreased the likelihood of theft.

When you insert the transponder key in 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 recognize that the key is genuine and allow fuel to flow, turn up the starter or begin it.

Some vehicles only recognize a certain type of transponder chips, depending on the manufacturer. This is why it is crucial to make sure that your locksmith for automotive is equipped to program your car's keys and fobs properly.

A reputable locksmith for automotive will have a multi-vehicle programming tool that can be used on a variety of different models and brands of cars.

They are not as common but there are automotive key programmers that can only be used on a specific type of vehicle. The best automotive locksmiths will have the appropriate equipment to tackle any type of vehicle, so be sure you choose a reputable firm that has these types of tools.

Key FOBs

Key FOBs are programmeable transponder chips that allow your vehicle to open doors and start the engine using the push of a button. They also have buttons you can press to trigger features such as door locks, trunk release or control of the fuel flap. Certain fobs come with additional functions that can be controlled by the push of a button like a "smart" key fob that allows you to get your car into tight parking spots similar to the Genesis GV60, Tesla or Genesis GV60.

While some replacement key fobs can be programmed by you with the help of a user manual however, you'll typically require an automotive locksmith to get a brand new one programmed in case yours stops working. This is because a professional locksmith has the right equipment and access to the programming tools needed to connect your car's computer to the OBD (OBD) port that is located under the steering wheel.

Most key fobs today have security features that make it difficult for attackers to clone or replicate the signals they transmit. These include pseudo-random sequence generators that generate a fresh unlock code every time you press the button on the key fob. This prevents attackers capturing and replaying the unlock signal in order to gain access to your vehicle.


In some instances you can purchase an alternative keyfob from a dealership or another retailer. Your locksmith at your auto will then program it to work with your car. This is due to the fact that most of the major US and Asian car makers have key fob programming protocols with third-party companies that create the tools locksmiths for auto utilize to program keys for their customers.

Certain aftermarket key fobs can be advertised as being compatible with all vehicles. However, locksmiths for automotive recommend against using them because they're likely to function poorly or not even work at all. They recommend buying fobs made specifically for your vehicle so that they will work properly and are less prone to issues like interference or incompatibility. This will save you money over the long term by avoiding expensive repairs or replacing the fobs.

The automotive industry has made huge advances in the last couple of decades. Today's vehicles are computer-driven. A transponder chip is an essential component of this technology. It has to be programmed by a locksmith mechanic or dealer to work. Key fobs come with built-in security features that prevent hot-wiring (like in a movie) and the car will not start if you don't have the right key.

Key fobs can be a little more complex than a traditional mechanical key. This is why they are handled by experienced professional auto locksmiths. The cost of the car key fob is according to the model and type of key, but it is generally between $85 to $400. This includes the labor to program the key fob and the costs for any required 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 work with the car's onboard computer. The software prevents unauthorized access by allowing the key to operate if it has been programmed to the car in question. If you replace your keys, you will need to program the new key fob to the car in order for it to work.

This is accomplished using a tool for programming car keys that is compatible with the vehicle's brand. This tool lets the locksmith connect to the OBD port (OBD) within the vehicle and then enter the programming mode. The key programming tool can be a handheld device that is inexpensive device or a high-end one that is capable of performing a wide range of things beyond just key programming (like reading and cloning eeprom files in the ECU).

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. It is best to delegate it to a professional with expertise with these systems.

Locksmiths can program keys quickly with onboard programming. If everything is done correctly it could take just one minute. If the key is not in the correct condition or the procedure isn't being followed exactly, the process could take as long as a half 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 very popular with locksmiths due their wide range of models for vehicles. The system cannot program every vehicle. They are also expensive. It's a good idea to buy a programmer that is updated regularly as the manufacturer releases new technologies. Your machine for programming will quickly become outdated if you don't take this step.
