Automotive Locksmith Key Programming
The majority of modern cars require some kind of key programming. Based on the model and manufacturer the procedure could be as simple as using a spare key to programme the computer onboard, 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 software and hardware for locksmiths in the automotive industry to use.
Transponder Chips
Most newer cars use transponder chips to stop car theft. These are tiny computer microchips that emit low-level radio signals. They have a unique serial number which authenticates your keys when you plug it into the ignition barrel. If your car doesn't recognise the signal it will shut down the engine. This technology has proved to be an enormous success in preventing auto theft. It also saves many car owners a significant amount of money since they don't have to replace their cars.
The basic idea behind the transponder system is to make it impossible for thieves to open the doors of your car without the proper key. In the past, thieves would use an ordinary screwdriver to force the ignition switch of your vehicle into "on" mode, or hot-wire it in order to bypass the system. Transponder chips have dramatically reduced the number of thefts.
When you insert the transponder keys into the ignition the signal is picked up by an antenna that is concealed around the barrel. The antenna is programmed with the frequency of the chip in the key. The computer onboard of the car will then recognise the key as valid and allow fuel flow, power the starter or begin the engine.
Certain vehicles only recognize a certain type of transponder chip according to the manufacturer. It is therefore essential that your locksmith in the automotive industry is equipped with the appropriate equipment to program your keys and remotes for your vehicle.
A reputable locksmith for automotive needs to have a multi-vehicle key programming tool that is compatible with different models and car brands. This is a cheaper solution than buying specific tools for each type of vehicle. There are also specially-designed key programming tools for automobiles that are only suitable for one particular brand of vehicle however they are not as popular. The most reliable automotive locksmiths will have the appropriate tools to work on any type of vehicle, so make sure you choose a reputable firm that has these types of tools.
Key FOBs

You can also use the buttons to activate features such as door locks, trunk releases or control of the fuel flap. Some fobs have additional functions that can be controlled with the press of a button like the "smart" key fob that lets you get your car into parking spaces that are difficult to access similar to the Genesis GV60, Tesla or Genesis GV60.
You can program replacement key fobs yourself using the help from the user guide, however you will need to call an automotive locksmith if the one you have isn't functioning.

The majority of key fobs come with security features that make it difficult for attackers to duplicate and copy the signals they transmit. Certain key fobs come with pseudo-random code generators that generate a new unlock code each time you press the button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In some cases, you can buy a replacement keyfob from a dealership or another retailer. Your locksmith at your auto will then program it to here 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 create the tools used by auto locksmiths to program their customers' keys.

Instead, they suggest buying fobs specifically designed for your vehicle so that you can be certain they'll work properly and are less susceptible to issues like interfering or incompatibility. This will save you money over time by avoiding costly repairs or replacements of your fobs.
Vehicle Manufacturers' Programming Tools
Automotive technologies have come a long way and today's vehicles need computer technology in order to function. One of the key components of this technology is a transponder chip that requires to be programmed to the vehicle by an auto locksmith or dealer/mechanic order to function. Key fobs are fitted with security features that prevent hot-wiring, like in a movie. The car will not start without the correct keys.

The cost of a key fob will vary depending on the car model and the type of key, but they typically run between $85 and $400. This includes the labor cost to program the keyfob and any replacement parts.
Car key fobs are more complicated because they utilize a software system that works with the computer onboard of the car. The software blocks unauthorized access by permitting the key to function if it has been programmed for the specific car. If you change your keys, you'll need to program the new key fob in 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 permits a locksmith to connect to the OBD port on the vehicle and then enter programming mode. The key programming tool can be a handheld device that is inexpensive device or a more expensive one that can perform various things beyond key programming (like reading and cloning the Eeprom files within the ECU).
While some may try to program their own keys with these tools, this is a job best left to a professional auto locksmith. Unless you're familiar with all the details of the various software systems, it's very easy to make a mistake and alter settings that could cause damage to the vehicle.

The EEPROM programming method is a different one that can be used to program new car keys. It is more complex and requires a deep understanding of electronic systems. It's best to leave it to a professional with knowledge of these systems.
Locksmiths can program a key quickly using onboard programming. It can take less than one minute if everything is completed correctly. However, if the key isn't in correct situation or the procedure isn't adhered to, it could take up to a half hour.
There are numerous key programmer scanners that support various models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro have become extremely popular with locksmiths due their broad range of vehicle models. However, no system will be able to program every vehicle in existence. These devices are also expensive. It is best to buy a programmer which will receive regular updates from the manufacturer whenever new technologies are introduced. Otherwise, your programming machine will become obsolete quickly.
