Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the model and make, the process may be as simple as using an additional key to program the onboard computer, or as complex as EEPROM or OBD2 programming.
Most US and Asian car manufacturers have programming protocols that they share with auto tool makers to allow them to develop software and hardware for locksmiths in the automotive industry to use.
Transponder Chips
The majority of newer cars have what are called transponder chips to prevent car theft. These are tiny computer microchips which emit radio waves of low-level. They have a unique digital serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal, it will shut down the engine. This technology has been an enormous success in preventing auto theft. This technology has also helped car owners save a huge deal of money as they do not have to buy new vehicles.
The principle of the transponder system is to make it hard for thieves to get into your vehicle without a valid key. In the past, thieves would simply push your ignition switch to the "on" position with an ordinary screwdriver or make use of hot-wires to bypass the system entirely. These types of thefts have been dramatically decreased with the introduction of the transponder chip.
When you insert the transponder key into the ignition, the signal is picked up by an antenna that is hidden within the barrel. The antenna is programmed to match the frequency of the chip in the key. The car's onboard computer will then recognize that the key is legitimate and allow fuel to flow, turn up the starter, or even start it.
Depending on the manufacturer, certain vehicles can only accept certain types of transponder chip. It is therefore essential that your automotive locksmith is equipped with the right equipment to program your keys and remotes for your vehicle.
A reliable locksmith for cars will utilize a multi-vehicle programmable device which can be used on many different automobile models and manufacturers. This is a much more cost-effective approach than purchasing separate tools for each type of vehicle. They are not as common, but there are specialised automotive key programmers that are able to only work on a particular brand of vehicle. The top automotive locksmiths have the right tools to work on any type of vehicle, so ensure you choose a reputable firm that offers these types of tools.
Key FOBs
As the name suggests, key FOBs contain transponder chips programmable that allow your vehicle to identify and unlock the doors or start the engine using push-button ignition. They also have buttons that you can push to activate features like door locks, trunk release or control of the fuel flap. Certain fobs can be controlled with the press of buttons. For example the "smart key" which allows you to summon your car to tight parking spaces, like the Genesis GV60 or a Tesla or Genesis GV60.
While certain replacement key fobs can be programmed by you with the aid of a user's guide however, you'll typically require an automotive locksmith to have a new one programmed if the one you have isn't functioning. A professional is better equipped to connect the computer of your vehicle via the OBD port on the steering wheel.
The majority of key fobs are equipped with security features to make it harder for attackers clone and replicate the signals they transmit. Certain key fobs feature pseudo-random code generators, which generate a different unlock code each time you press the button. This stops attackers from recording and replaying the unlock signal in order to gain access to your vehicle.
In most cases you can buy an additional key fob at the dealership or another retailer and have it programmable by your automotive locksmith to work with your specific vehicle. This is because the majority of major US and Asian auto manufacturers 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.
Certain aftermarket key fobs can be marketed as compatible with any vehicle. However, automotive locksmiths recommend against using them because they're more likely to perform poorly or not even work at all. Instead, they recommend purchasing fobs designed specifically for your vehicle so that you can be certain they'll work properly and are less prone to issues such as interfering or incompatibility. This will save money over time, as you avoid costly repairs or replacements of your fobs.
Vehicle Manufacturers' Programming Tool
The automobile industry has made significant strides in the last few decades. Today's cars are computer-driven. One of the most important components of this technology is a transponder chip which must be programmed into the vehicle by an expert locksmith or dealer/mechanic in order to work. Key fobs come with security features that prevent hot-wiring, as in a movie. The car will not start if the keys are not correct.
Key fobs are a bit more complex than the traditional mechanical key, read more which is why you'll typically find them in the hands of a skilled, professional auto locksmith. The cost of a key fob can differ based on the vehicle model and the type of key however they usually cost between $85 to $400. This includes the cost of labor to program the key fob and the costs for any required replacement parts.
Car key fobs are more complicated due to the fact that they use an operating system that communicates with the onboard computer of the car. The software blocks access to unauthorized users by permitting the key to function only if it's been programmed for the specific car. If you change your keys, you will have to program the new key fob in the car for it to function.
This is accomplished using a programing tool for keys for cars that are compatible with the vehicle's brand. This tool allows locksmiths to connect to the OBD port in the vehicle and then enter programming mode. The key programming device could be a handheld device that's affordable or fancy and can do more than just programming keys (like reading the eeprom file inside the ECU).
Although some people might attempt to program their own keys with these tools, this is something best left to an experienced auto locksmith. If you're not familiar with the details of the various software systems, it's very easy to accidentally alter settings that could damage the vehicle. The most important thing to keep in mind is that a skilled professional can help you avoid these problems.
On-Board programming
If your car is of a certain age, you'll still have a traditional key made of metal to open the doors and turn on the ignition. Modern cars have transponders that must be recognized and accepted by the computer system to start. This adds an extra layer of protection that can stop car thieves from starting a car stolen and driving away with it. A certified locksmith has the tools and software to create a new key that will work with the security system of your vehicle.
First, your locksmith will require a blank key that is compatible with the model and make of your vehicle. Once your locksmith has the key, he will connect the programming scanner to the diagnostic port of your vehicle. This will place the car into a special programming mode that allows the locksmith to add a new key into the system.
To do this, the key programmer scanner will communicate with the car's computer to send a specific code. The computer will be able to recognize this code and include it into the list of approved key. In certain instances the scanner will be able to remove keys that are 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. This is why it's best left to a professional that has extensive experience working on these types of systems.
Onboard programming is the most efficient method for locksmiths to program the new key. If everything is done correctly it could take as little as one minute. However, if the key isn't in proper state or the procedure isn't followed exactly, it can take up to a half hour.
There are numerous key programmer scanners that can be used with different makes and models of vehicles. Both the Smart Pro and Autel IM608 Pro have become very popular with locksmiths due their wide range of models for vehicles. However, neither will be able to program every single vehicle that exists. These devices are also expensive. It's best to purchase a programmer which will receive regular updates from the manufacturer when new technologies are developed. In the event that your machine is not updated, it will become obsolete quickly.
