Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on the vehicle's make and model, the procedure can be as easy as programming onboard using a spare working key or as complicated as OBD2 or EEPROM programming.
Most US and Asian car manufacturers have programming protocols that they share with auto tool manufacturers so that they can develop tools and hardware for automotive locksmiths to use.
Transponder Chips
Transponder chips are used in many newer cars to prevent car theft. These are microchips in the form of computers that emit low-level radio signals. They have a unique serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal, it will shut down the engine. 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 principle behind the transponder system is to make it impossible for thieves to get into your car without the proper key. In the past, thieves used an ordinary screwdriver to force the ignition switch in your car into "on" mode, or hot-wire it to bypass the system. These types of thefts have been dramatically reduced with the introduction of the transponder chip.
When you insert a transponder key into the ignition, it transmits an electrical signal that is received by a hidden antenna circling the barrel of the ignition. This antenna is programmed so that it can detect the particular frequency of the chip inside the key. The car's computer onboard will detect that the key is legitimate and allow fuel to flow, power up the starter or begin it.
Certain vehicles only recognize a certain type of transponder chips, depending on the manufacturer. It is therefore important that your automotive locksmith is equipped with the correct equipment to program your car's keys and remotes.
A reliable locksmith for cars will possess a multi-vehicle programing device which can be used with different car models and manufacturers. This is a less expensive alternative to purchasing individual tools for every brand of vehicle. There are also specially-designed key programming devices for automotive that can only be used on one particular brand of vehicle however, they are less popular. The best automotive locksmiths have the tools to work on any vehicle. Make sure you choose a reputable firm that has this kind of equipment.
Key FOBs
Key FOBs are programmeable transponder chips that allow your vehicle to unlock doors and start the engine using a push button ignition. You can also use the buttons to trigger features such as trunk locks, door locks or control of the fuel flap. Some fobs also have additional functions that can be controlled using the button presses like the "smart" key fob that allows you to get your car to parking spots that are tight, like you would with the Genesis GV60 or Tesla. Tesla or Genesis GV60.
You can program spare key fobs by yourself with the help of a user guide, but you'll need to contact an automotive locksmith in the event that yours isn't working. A professional locksmith is more equipped to connect the computer of your car via the OBD port under the steering wheel.
The majority of key fobs come with security features that make it difficult for attackers to replicate and clone the signals they transmit. They include pseudo-random sequence generators that generate a new unlock code each time you press the key fob's button. This stops attackers from recording and replaying the unlock signal in order to gain access to your car.
In certain instances you can purchase the replacement keyfob at an authorized dealer or another retailer. Your automotive locksmith will then program it to work with your vehicle. This is because the majority of the major US and Asian car makers share their key fob programming protocols with third-party companies who produce the tools locksmiths for auto use to program their customers' keys.
Some aftermarket key fobs may be advertised as being compatible with all vehicles. However, professional locksmiths advise against using them since they're likely to function poorly or even not even work at all. Instead, they suggest buying fobs that are specifically made for your vehicle, so that you can be sure they'll work properly and are less susceptible to issues such as interfering or not working. This will save you money over the long term by avoiding costly repairs or replacing the fobs.
Vehicle Manufacturers' Programming Tool

One of the most important components of this technology is a transponder chip which requires to be programmed to the vehicle by a locksmith or dealer/mechanic in order to work. Key fobs come 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 a little more complicated than a traditional mechanical key and are the reason you'll usually find them in the hands of an expert professional auto locksmith. The cost of a car key fob varies according to the type and model of key, but it is typically between $85 to $400. This includes the cost of labor to program the key fob and the costs for any necessary replacement parts.
To complicate the process, these car key fobs use a special software system to connect to the car's onboard computer. The software blocks unauthorized access by only allowing the key to function if it has been programmed for the specific car. This means that if you need your keys replaced, you'll have 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 your vehicle's brand. This tool allows a locksmith to connect to the OBD port on the vehicle and then enter programming mode. Key programming tools can be a handheld device that is inexpensive device or a fancy one that can perform many things that go beyond key programming (like reading and cloning EEEPROM files in the ECU).
While some people may attempt to program their own keys using these tools, this is an activity best left to a professional auto locksmith.

The key scanner that is programmed communicates with the computer in the vehicle to send an electronic code. The computer will be able to recognize the code and add it to the list of keys approved by. In some instances the scanner may also be able to erase keys that are stolen or lost from the system.
You can also program new keys by using the EEPROM. It is more complex and requires a thorough understanding of electronic systems. It is best to leave it to a professional with experience with these systems.
Onboard programming is the most efficient method for locksmiths to program an entirely new key. It can take less than a minute when everything is done correctly. If the key isn't in the right condition or the procedure isn't followed exactly, the process can be as long as half an hour.
There are many key programmer scanners that support different vehicle models and brands. Both the Smart Pro and Autel IM608 Pro are very popular among locksmiths due to their broad range of models for vehicles. However, neither can program every vehicle on the market.
