What Are Key Programmers? The majority of modern vehicles have ignition and key systems which require a reprogramming at some point. Key programmers can be useful in this case. There are three situations where shops may require key programming capabilities. The shop might need to program keys in three situations: a customer might want an additional key, or the keys are lost. OBD-II Key Programmer Units A car key programmer is a device that allows an individual to modify or add code in a transponder chip that is inside a vehicle's key fob. This can be done to allow another key to operate the car or to permit another person to drive the vehicle. These devices are costly and require training and knowledge in order to operate. These devices are typically used by auto repair shops or locksmiths with professional experience however, they are difficult to locate for mechanics at home. Some of the best key programmer units are designed to be easily operated, while others are more complex and are intended for professional use. They typically require a specific programming mode, and can be confusing to operate without proper instructions. The best unit will depend on the features you require. Some models even come with a remote control so you can use it sitting in the driver's seat. The Autel MaxiIM IM508S is a great option for those looking to be able to carry out more advanced key programming functions. It has several advantages over the Autel DS808 as well as MP808 that include key programming remote learning key generation, key generation and hex code deciphering. It has built-in WiFi connectivity that is very useful for garages and auto shops. Another option is the XTOOL Inplus IP616. It offers two methods to program keys: either by the type of vehicle or by the type. The “By vehicle” method is more straightforward and works for the majority of people, whereas the “By type” method requires a bit more technical expertise. It is a versatile tool that will save you time in your automotive repairs. The Xtool Inplus IK618 is a low-cost device that comes with a range of special functions. It can read PIN codes as well as perform hex-code reading, and offer more than 32 different reset functions. It is ideal for technicians in the automotive field and can be used to perform various diagnostic tasks. It has a large display that makes it easy to use. Self-Programming Keys In a majority of cases the reprogramming of key fobs or the creation of a new car key can be done by a locksmith local to you. However, this procedure requires the use of a device that is referred to as a “key programmer.” These devices can be standalone units or integrated into a more sophisticated scan tools designed by automotive manufacturers, mechanics and dealers. The main programmers are designed to communicate bidirectionally with the vehicle's OBD-II connector. They are compatible with a range of makes and models. Certain car manufacturers do not permit locksmiths from the local area to reprogram new keys to their vehicles, for security reasons. This prevents anyone from making a copy of your existing working key and then using it to steal your vehicle. In many instances, a car's computer won't allow keys to be programmed more then once. This is the way the system stops hot-wiring stolen vehicles like in films. Even a T-800 Terminator would not be able to escape with Sarah Conner's car! To this end, certain car manufacturers don't include instructions in their owners manuals for making additional keys or reprogramming a key fob. These companies are assuming that their customers are idiots and can't figure out things by themselves, and they make it more difficult to do so. Fortunately, most major US and Asian automakers have their key programming protocols with tool makers that develop and market these kinds of devices. Thus, there is a wide variety of key programmers available for these models of vehicles that permit reprogramming existing keys or the creation of additional fobs. The devices are priced differently in terms of cost and functionality but they are affordable enough to be used by a locksmith for this type of service. The simplest, least expensive models are designed for cars with a single or two and the most advanced, sophisticated models are offered to dealers at thousands of dollars. It is recommended to read online reviews and do some research before you buy an important programmer. Transponder Clone Keys When a car key is inserted into the ignition, it transmits an low-level radio signal to the transponder chip. This signal contains an individual serial number that authenticates that the key is the right one for the vehicle. The system is designed to make it difficult to steal a vehicle since the vehicle will only begin to start when it receives the right signal from the right key. A key cloning device could be used to duplicate keys without the need to re-programme the computer of the car to recognize the new one. Cloning a car key requires two things: a method to get the data off of the original key and a machine that is able to transfer the data to a different chip. Most conventional cloning devices work well with a variety of keys. However, some machines work with a limited number of keys and brands. A good cloning program will not only determine whether or not there's a microchip in the key, but also what kind of chip it is. This feature is important since there are a variety of kinds and brands of chips in use today. It is easy to mix up the chips when swapping them between different shells, so it is essential that a cloning system discern between them. The most advanced systems will even have an identification feature for each type of chip. This helps prevent the key from being programmed to a wrong vehicle, and it is also a defense against who steals the original key in order to use it in another car. Having the proper equipment allows locksmiths to provide customers on-site replacement of keys and also help them avoid the cost and burden of taking their cars back to a dealership. In addition the equipment permits locksmiths to offer more services and gain new clients. In just a few years just only a handful of keys per week will be enough to pay for the majority of these equipment. This is the perfect time to begin offering this service, since many of the leading automakers are pushing dealers to offer more key duplication and replacement. Key Fobs Key fobs are useful for a variety of purposes. They are popular in apartment building access systems and are also used to control small household devices, like garage door openers. They utilize radio frequency identification, or RFID. When you place your fob against the reader, it sends a unique frequency that is recognized by the reader, allowing access. transponder key programmer are typically controlled and monitored from central computers which means you can grant different levels of access to different individuals. You can also utilize the key fob to lock or unlock your vehicle. This is much safer than a physical car key, as it is not a risk that someone could copy the key. It is also possible to deactivate the key fob in the event that it gets stolen or lost. A key fob can be used to gain access to facilities without the requirement for an account number or password. This is a great feature for commercial and industrial environments where it is difficult to monitor and control employee accessibility. Fobs can also be used to prevent cyber-attacks. These are caused by keys that are lost, misplaced or copied and give malicious users access to the system, allowing them to install malware, steal information or engage in other cybercrimes. Fobs are a fantastic option for apartment complexes and gated communities, as they can be programmed to permit residents in to common areas, such as the community pool or storage facilities. They can also be programmed to open doors at specific residences, making it easy for a tenant to give access to cleaning crews, babysitters and pet walkers. To program a key fob, you'll need a tool that can communicate with the vehicle's computer. Many locksmiths and auto technicians use a tool known as the Smart Pro, which is a powerful tool for programming that can handle all major brands and models. It can also read and program transponder chips, clone keys and even perform OE level programming. While it's not cheap, it's an excellent choice for anyone who needs an effective key programming tool.
