Automotive Locksmith Key Programming The majority of modern cars require some kind of key programming. Based on the car's make and model, the process can be as easy as onboard programming with a spare working key or as complex as OBD2 or EEPROM programming. Most US and Asian auto manufacturers share their programming protocol with auto tool manufacturers, so they can create tools or hardware for automotive locksmiths. Transponder Chips Most newer cars use transponder chips in order to prevent theft. These are tiny computer microchips that emit radio waves at a low level. They have a unique serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal it will shut down. This technology has been a huge success in preventing theft of cars. This technology has also helped car owners save a good deal of money since they don't have to purchase new cars. The principle behind the transponder system is to make it difficult for thieves to get into your car without the proper key. In the past, car thieves used a flat screwdriver to force the ignition switch of your vehicle to go into “on” mode, or wire it hot to get around the system. These types of thefts have been dramatically reduced thanks to the introduction of the transponder chip. When you insert the transponder key into the ignition the signal is received by an antenna that is concealed around the barrel. The antenna is programmed with the frequency of the chip within the key. The car's onboard computer will then recognize that the key is genuine and allow the fuel to flow, then power up the starter, or even begin it. Based on the manufacturer, certain vehicles can only recognize the specific type of transponder chip. It is therefore essential that your locksmith for cars 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 works with different models and car brands. This is a less expensive solution than buying specific tools for each type of vehicle. These are less common, but there are specialised automotive key programmers that are able to only work on a specific brand of vehicle. The top automotive locksmiths have the tools to work on any vehicle. Make sure you select a reliable company that is equipped with this type of equipment. Key FOBs The name implies that key FOBs house the programmable transponder chips that enable your car to recognize and unlock the doors, or start the engine using push-button ignition. They also have buttons that you can press to activate features like door locks, trunk release or fuel flap control. Certain fobs can be controlled using buttons. For example an “smart key” that allows you summon your car to tight parking spaces, like a Tesla or Genesis GV60. You can program some spare key fobs by yourself with the help of the user guide, however you'll need to contact an automotive locksmith if the one you have isn't functioning. This is because an expert locksmith has the right equipment and access to the programming tools needed to connect your car's computer through the on-board diagnostics (OBD) port that is located under the steering wheel. The majority of key fobs come with security features that make it more difficult for criminals to replicate and clone the signals that they transmit. Certain key fobs come with pseudo-random code generators that generate a unique unlock code each time you press the button. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle. In certain instances you can purchase a replacement keyfob from an auto dealer or other retailer. Your automotive locksmith will then program it to work with your vehicle. This is due to the fact that most of the major US and Asian car makers share their key fob programming protocols with third-party companies that produce the tools locksmiths employ to programme keys for their customers.

This includes the labor to program the key fob and the costs for any required replacement parts. To make the process more difficult to make the process more complicated, these key fobs for cars utilize a specific software system to work with the car's onboard computer. The software blocks access to unauthorised users by only permitting keys that have been programmed for a specific vehicle to work.

The most popular method to do this is by using the car key programming tool that is compatible with the brand of the vehicle.

The key programming tool could be a handheld device that is inexpensive device or a fancy one that can do many things that go beyond key programming (like reading and cloning the eeprom files in the ECU). While some may try to program their own keys with these tools, it's something best left to an experienced auto locksmith.
