Automotive Locksmith Key Programming Modern cars need some type of key programming. Based on automotive key programming 's make and model, the process can be as simple as programming onboard using a spare working key or as complex as EEPROM or OBD2 programming. Most US and Asian auto manufacturers use the same programming protocols as auto tool makers, which means they can design tools or hardware for automotive locksmiths. Transponder Chips Transponder chips are found in a lot of modern cars to guard against theft of vehicles. These are tiny computer microchips which emit radio waves at a low level. They have a unique digital serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your vehicle isn't able to recognize the signal, the engine will be shut down. This technology has been extremely successful in preventing car theft. It has also saved many car owners a lot of money because they don't have to buy new their cars. The transponder system's basic idea is to make it difficult for thieves to start your vehicle without a valid key. In the past, thieves would use an ordinary screwdriver to force the ignition switch of your vehicle into the “on” mode or even wire it hot to get around the system. Transponder chips have dramatically reduced these types of thefts. When you place the transponder key in the ignition, the signal is received by an antenna hidden around the barrel. The antenna is programmed to detect the particular frequency of the chip within the key. The car's onboard computer will recognize that the key is genuine and allow the fuel to flow, then power up the starter or begin it. Based on the manufacturer, some vehicles will only recognise certain types of transponder chip. This is why it's essential to ensure that your automotive locksmith has the appropriate equipment to program your vehicle's keys and fobs correctly. 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 more cost-effective approach than purchasing individual tools for each brand of vehicle. They are not as common but there are 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. Be sure to choose an established company that has this type of equipment. Key FOBs As the name implies, key FOBs contain transponder chips that can be programmed to allow your vehicle to recognize and open the doors or start the engine using push-button ignition. You can also press buttons to activate features like trunk releases, door locks or fuel flap controls. Certain fobs can be controlled by pressing buttons. For instance an “smart key” which allows you to summon your car to tight parking spaces, such as a Tesla or Genesis GV60. While some replacement key fobs can be programmed by you with the help of a user manual but you'll usually require an automotive locksmith to get a new one programmed in case yours stops working. This is because a professional has the right equipment and access to the programming tools required to connect your car's computer to the on-board diagnostics (OBD) port beneath the steering wheel. The majority of key fobs are equipped with security features to make it harder for attackers duplicate and copy the signals they transmit. They include pseudo-random sequence generators that generate a fresh unlock code each time you press the button on the key fob. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle. In most cases you can buy an additional key fob at the dealer or other retailer and have it programmable by a locksmith for your vehicle to work with your particular vehicle. This is because the majority of major US and Asian auto manufacturers share their key-fob programming protocols with the third-party companies who create the tools used by locksmiths for programming their customers' keys. While some of the aftermarket key fobs are advertised as compatible with any vehicle however, the majority of locksmiths for automotive don't recommend using them because they're likely to work poorly or not at all. Instead, they suggest purchasing fobs that are specifically made for your specific vehicle so that you are certain they'll function properly and be less susceptible to issues such as interfering or incompatibility. This will save money over time, as you avoid costly repairs or replacements for your fobs. Vehicle Manufacturers' Programming Tools The automobile industry has made significant advancements in the past few decades. Today's cars are computer-driven. One key element of this technology is a transponder chip which needs to be programmed to the vehicle by an expert locksmith or dealer/mechanic in order to function. Key fobs are fitted with security features that prevent hot-wiring like in a film. The car will not start without the correct keys. Key fobs can be somewhat more complicated than a standard mechanical key. This is why they are usually placed in the hands of experienced, professional auto locksmiths. The cost of the car key fob is according to the type and model of key, but is typically between $85 to $400. This includes the labor to program the key fob, as well as the costs for any necessary replacement parts. To make the process more difficult, these car key fobs utilize a specific software system to communicate with the car's onboard computer. The software blocks access by unauthorised persons by only allowing keys programmed specifically for a particular car to work. This means that if you get your keys replaced, you'll need to have the new key fob programed to the car in order to function. This is accomplished by using a tool for programming 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 the programming mode. Key programming tools can either be an inexpensive handheld device or a more expensive one that can do a wide range of things beyond key programming (like reading and cloning the EEEPROM files in the ECU). Some people may attempt to program their keys themselves using these tools. However, this is best left to an expert auto locksmith. If you're not familiar with the aspects of the various software systems, it's very easy to accidentally alter settings that could damage the vehicle. It's important to remember that a knowledgeable professional can assist you in avoiding these issues. On-Board programming If your car isn't as old it could still be equipped with a metal key that you can use to unlock doors and turn on the ignition. Modern cars come with a transponder that must be recognized and accepted by the computer system to start. This is an extra layer of protection that can stop car thieves from starting a stolen car and then driving off with the car. A locksmith who is certified has the tools and software to create a key that is compatible with the security system in your car. First, your locksmith needs to purchase an uncut key that is compatible with the make and model of your car. Once the key is in hand the locksmith will connect the programming scanner to your car's diagnostic port. This will put the vehicle into an exclusive programming mode that will allow the locksmith to add a new key into the system. The key scanner is programmed to communicate with the computer in the vehicle to transmit an electronic code. The computer will detect this code and add it to the list of keys that are approved. In some cases the scanner may also be able to remove keys that have been stolen or lost from the system. You can also program new keys using EEPROM. It is more complex and requires a thorough understanding of electronic systems. It is best to delegate it to a professional with knowledge of these systems. Onboard programming is the quickest way for a locksmith to program the new key. If everything is done properly it can take as little as one minute. If the key isn't in the correct condition or the procedure isn't followed precisely, the procedure could be as long as half an hour. There are a variety of key programmer scanners available 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 wide range of vehicle models. However, neither can program every single vehicle that exists. Furthermore, these systems are expensive. It's a good idea to purchase a programer that receives regular updates as the manufacturer develops new technologies. Your computer's programming software will soon become obsolete if you do not take this step.
