Automotive Locksmith Key Programming
The majority of modern cars require some kind of key programming. Depending on your vehicle's model and make the process could be as simple as using an extra key to programme the computer onboard, or as complex as EEPROM or OBD2 programming.
Most US and Asian auto manufacturers use the same programming protocols as auto tool manufacturers, so they can design tools or hardware for locksmiths in the automotive industry.
Transponder Chips
Most newer cars use transponder chips in order to prevent theft. These are tiny computer microchips that emit radio signals at a low level. The microchips are equipped with a unique serial number that authenticates your key when you insert it into the ignition barrel. If your car doesn't recognise the signal it will stop the engine. This technology has been extremely successful in preventing theft of cars. This technology has also helped car owners save a huge deal of money since they don't have to replace their vehicles.
The principle behind the transponder system is to make it impossible for thieves to open the doors of your car without a key. In the past, thieves would simply force your ignition switch to the "on" position using an ordinary screwdriver or hot-wire the car to bypass the system completely. Transponder chips have drastically reduced the number of thefts.
When you place the transponder key into the ignition, the signal is received by an antenna hidden around the barrel. This antenna is programmed so that it can read the specific frequency of the chip inside the key. The car's onboard computer will then detect that the key is legitimate and allow fuel to flow, power up the starter, or even start it.
Some vehicles only recognize a certain type of transponder chips according to the manufacturer. It is therefore important that your locksmith in the automotive industry is equipped with the right equipment to program your car's keys and remotes.
A reliable locksmith for cars will utilize a multi-vehicle programmable tool that can be used on a variety of different models and brands of cars. This is a cheaper solution than buying specific tools for each type of vehicle. These are less common but there are automotive key programmers that can only work on a particular type of vehicle. The best automotive locksmiths will have the proper tools to work on any type of vehicle, so ensure you choose a reputable business that offers these types of tools.
Key FOBs
Key FOBs are programmeable transponder chip devices that allow your vehicle to unlock doors and start the engine with a push button ignition. They also have buttons that you can push to activate features such as door locks, trunk release or control of the fuel flap. Certain fobs come with additional functions that can be controlled by the push of a button for example, the "smart" key fob that allows you to summon your car to parking spots that are tight as you would with the Genesis GV60, Tesla or Genesis GV60.
You can program spare key fobs by yourself with the help of the user guide, however you'll need to call an automotive locksmith if the one you have has stopped working. This is because a professional locksmith has the right equipment and access to the tools for programming needed to connect your car's computer to the OBD (OBD) port beneath the steering wheel.
Today, most key fobs include security features that make it difficult for hackers to clone or 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 to gain access to your vehicle.
In many cases you can buy an alternative key fob from the dealer or other retailer and then have it programmed by your automotive locksmith 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 who program their customer's keys.
Although some key fobs from the aftermarket are marketed as being compatible with any vehicle, most automotive locksmiths don't recommend using them because they are likely to function poorly or not here at all. They recommend buying fobs made specifically for your vehicle to ensure they work correctly and are less susceptible to issues such as interference or incompatibility. This will save you money in the end by avoiding expensive repairs or replacing your fobs.
Tool for programming the vehicle manufacturers
Automotive technologies have advanced considerably, and today's vehicles require computer technology in order to function. A transponder chip is an important part of this technology. It needs to be programmed by a locksmith mechanic or dealer to work. Key fobs with embedded security features that prevent hot-wiring (like in a film) and the car won't start if it doesn't have the right key.
These key fobs are a bit more complicated than a traditional mechanical key, which is why you'll typically find them in the hands of an expert, professional auto locksmith. The cost of a car key fob varies according to the type and model of key, but is generally between $85 to $400. This includes the labor cost to program the keyfob, as well as any replacement parts.
To make the process more complicated, these car key fobs use a special software system to connect to the car's onboard computer. The software blocks access to unauthorised users by only allowing keys that have been programmed for a specific vehicle to function. This means that if you need your keys replaced, you'll need have the new key fob programmed to the car in order to function.
This is accomplished by using a programing tool for keys for cars that are compatible with your vehicle's brand. This tool permits a locksmith to connect to the OBD port on the vehicle and then enter the programming mode. The key programming device could be a handheld device that is affordable or extravagant and can do more than just programming keys (like reading the eeprom files in the ECU).
While some may try to program their own keys with these tools, it's something best left to an experienced auto locksmith. Unless you're familiar with all the ins and outs of the various software systems, it's very easy to accidentally change settings that could potentially damage the vehicle. It's crucial to remember that an experienced professional will 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 traditional metal key to open the doors and turn over the ignition. Modern cars have a transponder that must be recognized and accepted by the computer system in order to start. This is an additional security measure to prevent thieves from starting and then driving off with a stolen vehicle. A locksmith who is certified will have the right tools and software to create a new key that is compatible with your car's security system.
The locksmith needs to purchase a blank key that is compatible with the make and model of your car. Once the key is received the locksmith will connect the programming scanner to the diagnostic port of your car. This will place the car into a special programming mode which 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 an exact code. The computer will detect this code and include it to the list of keys that are approved. In certain instances, the scanner will also be able to delete lost or stolen keys from the system.
You can also program new keys by using EEPROM. It is more complex and requires an in-depth understanding of how electronic systems function. This is why it should be left to a professional that has extensive experience working with these kinds of systems.
Onboard programming is the fastest way for a locksmith to program the new key. If everything is done correctly, it can take as little as one minute. However, if the key isn't in proper state or the procedure isn't adhered to, it could take as long as a half hour.
There are many different key programmer scanners that support different models and makes of vehicles. The Smart Pro and the Autel IM608 Pro are both very popular amongst locksmiths because they can be used with a variety of automobile models. No system can program every vehicle. These devices are also expensive. It's a good idea purchase a programer that will get regular updates when the manufacturer introduces new technologies. Your computer's programming software will soon become obsolete if you don't take this step.
