Automotive Locksmith Key Programming
Modern cars need some form of key programming. Depending on the vehicle's make and model, the procedure could be as simple as onboard programming using a spare key that works or as complex as EEPROM or OBD2 programming.
Most US and Asian automobile manufacturers share their programming protocols with auto tool manufacturers so that they can develop tools and hardware for locksmiths in the automotive industry to use.
Transponder Chips
The majority of newer cars have what are called transponder chips in order to prevent theft. These are small computer microchips that emit low-level radio signals. They have a unique serial number which authenticates your keys when you insert it into the ignition barrel. If your vehicle isn't able to 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 purchase new cars.
The fundamental idea behind the transponder system is to make it impossible for thieves to get into your car without a key. In the past, car thieves would simply force your car's ignition switch into the "on" position using a flat screwdriver or even hot-wire the car to bypass the system altogether. Transponder chips have drastically reduced these types of thefts.
When you insert a transponder key into the ignition, it will transmit the signal which is picked up by a hidden antenna circling the barrel of the ignition. The antenna is programmed to detect the specific frequency of the chip inside the key. The computer onboard of the car will then recognize the key as being valid and allow fuel flow, power the starter or start the engine.
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 for automotive has the right equipment to program your vehicle's keys and fobs properly.
A good automotive locksmith will utilize a multi-vehicle programmable device which can be used on many different models and brands of cars. This is a cheaper alternative to purchasing specific tools for each type of vehicle. There are also specialised key programming devices for automotive that can only be used on specific brands of vehicles, but these are less common. The best automotive locksmiths will have the right tools to deal with any kind of vehicle, so be sure you find a reputable company with these kinds of tools.
Key FOBs
Key FOBs are programmable transponder chip devices that allow your vehicle to unlock doors and begin the engine with a push button ignition. It is also possible to press buttons to activate features like door locks, trunk releases or control of the fuel flap. Some fobs can be controlled using buttons. For example the "smart key" that allows you summon your car to tight parking spaces, like a Tesla or Genesis GV60.
While some replacement key fobs can be programmed by you using the aid of a user's guide, you'll often need an automotive locksmith to get a brand new one programmed in case yours stops working. This is because a professional has the specialized equipment and access to the programming tools required to connect your car's computer via the on-board diagnostics (OBD) port that is located under the steering wheel.
Most key fobs today include security features that make it difficult for attackers to duplicate or duplicate 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 an alternative keyfob from an auto dealer or other retailer. Your locksmith at your auto will then program it to work with your vehicle. This is due to the fact that most of the major US and Asian car manufacturers use key fob programming protocols with third-party companies that make the tools that locksmiths employ to program keys for their customers.
Some aftermarket key fobs may be advertised as being compatible with all vehicles. However, locksmiths for automotive advise against using them since they are likely to work poorly or not work at all. They suggest purchasing fobs that are designed specifically for your vehicle to ensure they work correctly and are less prone to issues like interference or incompatibility. This will save you money in the end by avoiding expensive repairs or replacing your fobs.

Key fobs are fitted with security features that prevent hot-wiring, like in a film. The car won't start without the correct keys.
Key fobs are slightly more complicated than a conventional mechanical key. This is why they are handled by experienced, professional auto locksmiths. The cost of a car key fob varies depending on the type and model of key, but is typically 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 use a special software system to communicate with the car's onboard computer. The software blocks unauthorized access by only allowing the key to operate if it has been programmed to the car in question. This means that if you get your keys replaced, you'll need have the new key fob programed to the car in order for it to function.
The most common method to do this is by using a car key programming tool that is compatible with the model of the vehicle. This tool allows locksmiths to connect to the OBD port on the vehicle, and then enter the programming mode. Key programming devices can be a handheld device that is inexpensive or one that is fancy and can do more than just programming keys (like reading the eeprom file in the ECU).

EEPROM programming 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's best to leave it to a professional with expertise with these systems.
Locksmiths can program keys quickly by using onboard programming. If everything is done correctly, it can take as little as one minute. However, if the key isn't in correct condition or the procedure is not followed exactly, it can take up to an hour.
There are numerous key programmer scanners on the market that work with various vehicle models and makes. Both the Smart Pro and Autel IM608 Pro have become very popular with locksmiths due to their broad range of vehicle models. However, neither can be programmed for every vehicle on the market. These machines are also quite expensive. It is a good idea to purchase a programer that will get regular updates when the manufacturer introduces new technologies.
