Automotive Locksmith Key Programming Modern cars require some type of key programming. Depending on the vehicle's make and model, the process could be as simple as onboard programming using a spare working key or as complex as EEPROM or OBD2 programming. The majority of US and Asian automakers share their programming protocol with auto tool makers, so they can create hardware or software for automotive locksmiths. Transponder Chips Most newer cars use what are called transponder chips to stop car theft. These are tiny computer microchips which emit radio waves at a low level. They have a unique serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal it will stop the engine. This technology has proven to be an enormous success in preventing theft of cars. This technology has also helped car owners save a huge deal of money as they do not have to replace their vehicles. The fundamental idea behind the transponder system is to make it impossible for thieves to get into your vehicle without a valid key. In the past car thieves would use the flat screwdriver to push the ignition switch in your car into “on” mode or even hot-wire it in order to get around the system. Transponder chips have drastically decreased the likelihood of theft. When you insert a transponder keys into the ignition, it will transmit a signal that is detected by a hidden antenna around the barrel of the ignition. This antenna is programmed to detect the particular frequency of the chip within the key. The car's computer onboard will detect that the key is valid and allow fuel to flow, power up the starter, or even start it. Some vehicles only recognize a certain type of transponder chip depending on the manufacturer. This is why it's important to ensure that your automotive locksmith has the appropriate equipment to program your car's keys and fobs properly. A good automotive locksmith will have a multi-vehicle programming device that can be used with different models and brands of cars. This is a cheaper option than purchasing separate tools for each brand of vehicle. There are also specially-designed automotive key programmer devices that are only suitable for one particular brand of vehicle, but these are less popular. The top automotive locksmiths have the proper tools to deal with any kind of vehicle, so be sure you find a reputable company that has these types of tools. Key FOBs As the name suggests, key FOBs are home to the transponder chips that can be programmed to enable your vehicle to identify and unlock the doors or start the engine with a push-button ignition. They also have buttons you can push to activate features such as door locks, trunk release or fuel flap control. Some fobs can be controlled by pressing buttons. For instance an “smart key” that allows you summon your car to parking spaces, like a Tesla or Genesis GV60. While some replacement keys can be programmed by you using the help of a user manual however, you'll typically require an automotive locksmith to get a new one programmed in case yours stops working. A professional is better equipped to connect the computer of your vehicle to the OBD port under the steering wheel. The majority of key fobs are equipped with security features that make it more difficult for criminals to clone and replicate the signals they transmit. They include pseudo-random generators that generate a new unlock code every time you press the key fob's button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle. In most instances you can buy an alternative key fob from the dealer or other retailer and have it programmed by your locksmith in your car to fit your particular vehicle. This is because the majority of major US and Asian automakers share their key-fob programming protocols with the third-party companies who create the tools used by auto locksmiths to program their customer's keys. While some aftermarket key fobs are advertised as compatible with all vehicles however, the majority of locksmiths for automotive don't recommend using them because they will likely only work poorly or not at all. They suggest purchasing fobs that are designed specifically for your vehicle to ensure they will work properly and are less prone to issues like interference or incompatibility. This will save money over time, as you avoid costly repairs or replacements of your fobs. Vehicle Manufacturers' Programming Tools The automotive industry has made huge strides in the last few decades. Today's cars are computer-driven. One of the key components of this technology is a transponder chipset that requires to be programmed to the vehicle by an expert locksmith or dealer/mechanic in order to work. Key fobs are fitted with security features that prevent hot-wiring like in a movie. The car will not start without the correct keys. These key fobs are a bit more complicated than a traditional mechanical key and that's why they are usually in the hands of a skilled, professional auto locksmith. The cost of a key fob may differ based on the vehicle model and the type of key however, they generally cost between $85 to $400. This includes labor costs to program the keyfob and any replacement parts. To make the process more complicated the car key fobs utilize a specific software system to connect to the car's onboard computer. The software blocks access by unauthorised persons by only allowing keys that have been programmed for a specific car to function. This means that if your keys replaced, you'll need have the new key fob programed to the car 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 in the vehicle and then enter the programming mode. The key programming tool could be a handheld device that is inexpensive device or a high-end one that can do various 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, it's something best left to an experienced auto locksmith. It's easy to make a mistake using the software systems if you don't know the nuances. This could result in damage. It's important to keep in mind that an experienced professional will help you avoid these problems. On-Board Programming If your vehicle is older than you that you'll have a traditional key made of metal to open the doors and turn on the ignition. However, modern cars come with transponder chips that must be recognized by the computer system of the car to allow it to start. This is an additional layer of security to keep thieves from starting and then driving off with a stolen vehicle. A locksmith who is certified has the tools and software necessary to program a key that can function in your car's system. First, your locksmith will require a blank key that is compatible with the model and make of your vehicle. Once the key is in your possession, your locksmith will link the programming scanner to the diagnostic port of your car. This will put the car in a special programming mode, which allows locksmiths to add the key to the system. The key programmer scanner communicates with the computer in the vehicle to send an electronic code. The computer will recognize the code and add it to the list of keys that are approved. In some cases, a scanner can also remove keys that have been stolen or lost. The EEPROM programming method is a different one that can be used to program new car keys. It is more complicated and requires an in-depth understanding of how electronic systems work. This is why it's best left to a professional that has years of experience working on these types of systems. Onboard programming is the most efficient way for a locksmith to program a new key. It can take as little as a minute when everything is done correctly. If the key isn't in the correct condition or the procedure isn't followed precisely, the procedure could take up to half an hour. There are many different key programmer scanners that can be used with different makes and models of vehicles. The Smart Pro and the Autel IM608 Pro are both popular amongst locksmiths because they can be used with a variety of automobile models. However, neither can program every vehicle in existence. These devices are also expensive. It's best to purchase an instrument that receives regular updates from the manufacturer whenever new technologies are released. If not, your computer will be obsolete in a short time.
