Automotive Locksmith Key Programming
Modern cars require some type of key programming. Based on the car's make and model, the process could be as simple as onboard programming using a spare key that works or as complicated as EEPROM or OBD2 programming.
Most US and Asian automakers use the same programming protocols as auto tool manufacturers, so they can develop hardware or software for locksmiths in the automotive industry.
Transponder Chips
Most modern cars are equipped with transponder chips to stop car theft. These are tiny computer microchips which emit radio waves at a low level. They have an unique serial number that authenticates your keys when you insert it into the ignition barrel. If your vehicle does not recognize the signal it will shut down. This technology has been an enormous success in preventing car theft. This technology has also helped car owners save a good deal of money as they do not have to purchase new cars.
The basic concept behind the transponder system is to make it difficult for thieves to get into your vehicle without the correct key. In the past, car thieves would simply push your ignition switch to the "on" position using the flat screwdriver, or hot-wire the car to bypass the system entirely. Transponder chips have dramatically decreased the likelihood of theft.
When you insert a transponder keys into the ignition, it will send an electrical signal that is picked up by a hidden antenna around the barrel of the ignition. The antenna is programmed with the frequency of the chip in the key. The car's onboard computer will detect that the key is valid and allow the fuel to flow, then power the starter or start it.
Some vehicles only recognize a certain type of transponder chip, depending on the manufacturer. This is why it is crucial to make sure that your locksmith in the automotive industry is equipped to program your car's keys and fobs properly.
A reputable locksmith for automotive will utilize a multi-vehicle programmable tool that can be used on many different models and brands of cars. This is a cheaper solution than buying separate tools for each brand of vehicle. There are also specialised key programming tools for automobiles that can only be used on one particular brand of vehicle, but these are less frequently used. The most reliable automotive locksmiths will have the right equipment to tackle any type of vehicle, so ensure you find a reputable company with these kinds of tools.
Key FOBs
The name implies that key FOBs are home to the programmable transponder chips that enable your vehicle to recognize and open the doors or start the engine using a push button ignition. They also have buttons that you can press to activate features such as trunk release, door locks or control of the fuel flap. Some fobs can be controlled using buttons. For example, a "smart key" that allows you summon your car to parking spaces, like a Tesla or Genesis GV60.
You can program some replacement key fobs yourself using the help of a user guide, but you'll need to contact an automotive locksmith in the event that yours has stopped functioning. This is because a professional has the specialized equipment and access to the programming tools needed to connect your car's computer to the OBD (OBD) port located beneath the steering wheel.
The majority of key fobs today include security features that make it difficult for attackers to duplicate or copy the signals they transmit. Certain key fobs come with pseudo-random code generators, which generate a different 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 most instances you can buy an alternative key fob from the dealer or from another retailer and have it programmable by a locksmith for your vehicle to be compatible with your specific vehicle. This is because the majority of major US and Asian automakers use the same key-fob programming protocol with the third-party firms who produce the tools used by auto locksmiths to program their customer's keys.
While some aftermarket key fobs are marketed as being compatible with any vehicle, most automotive locksmiths don't recommend using them since they will likely only work poorly or not at all. They suggest buying fobs designed specifically for your vehicle to ensure they will work properly and are less prone to issues such as interference or incompatibility. This will save you money over the long term by avoiding costly repairs or replacing the fobs.
Vehicle Manufacturers' Programming Tool
Automotive technologies have progressed a lot and today's vehicles need computer technology to function. One of the most important components of this technology is a transponder chip that must be programmed into the vehicle by an auto locksmith or dealer/mechanic order to work. Key fobs come with built-in security features that prevent hot-wiring (like in a film) and the car won't start if it doesn't have the proper key.
These key fobs are a bit more complex than your traditional mechanical key, which is why you'll typically find them in the hands of a skilled, professional auto locksmith. The cost of the car key fob is according to the type and model of key, but is usually between $85 and $400. This includes the cost of labor to program the keyfob as well as any replacement parts.
To make the process more complicated, these car key fobs utilize a specific software system to work with the car's onboard computer. The software prevents unauthorised access by only allowing keys that have been programmed specifically for a particular car to function. If you change your keys, you'll need to program the new key fob into the car to allow it to work.
The most popular method to accomplish this is using an auto key programming tool that is compatible with the model of the vehicle. This tool allows locksmiths to connect to the OBD port of the vehicle, and then enter the programming mode. The key programming tool can be a simple handheld device or a fancy one that can do a wide range of things beyond just key programming (like reading and cloning Eeprom files within the ECU).
Some people try to program their keys on their own using these tools. However this should be left to an experienced auto locksmith. If you're not aware of all the details of the various software systems, it's possible to make a mistake and alter settings that could cause damage to the vehicle. The most important thing to keep in mind is that an experienced professional can assist you in avoiding these issues.
On-Board Programming
If your vehicle is older than you to be considered old-fashioned, you'll have a key from the past to use to unlock the doors and transponder key programming turn off the ignition. Modern cars come with a transponder chip that must be recognized by the car's computer system to begin. This adds another security measure to prevent thieves from stealing the car and driving away with a stolen car. A locksmith certified will have the tools and software needed to program a key that can work in your car's system.
Your locksmith will have to obtain a key blank that is compatible with your vehicle's make and model. Once the key is received, your locksmith will link the scanner for programming to your car's diagnostic port. This will put your car into a special programming mode that will allow the locksmith to add a new key into the system.
To accomplish this, the key programmer scanner will communicate with the car's computer to send a particular code. The computer will be able to recognize this code and include it into the list of approved key. In some instances, the scanner will also be able to delete keys that have been stolen or lost from the system.
You can also program new keys using the EEPROM. It is more complicated and requires a deep understanding of electronic systems. It is best to delegate it to a professional who has knowledge of these systems.
Onboard programming is the quickest method for locksmiths to program an entirely new key. It takes as little as one minute if everything is done correctly. If the key isn't in the right condition or the procedure isn't followed precisely, the procedure could take as long as a half hour.
There are many key programmer scanners on the market that work with various vehicle models and brands. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due their wide range of models for vehicles. There is no system that can program every vehicle. In addition, these machines cost a lot. It's a good idea purchase a programer that will get regular updates as the manufacturer releases new technologies. Otherwise, your programming machine will soon become obsolete.
