Automotive Locksmith Key Programming
Modern cars need some kind of key programming. Depending on the vehicle's make and model, the procedure could be as simple as onboard programming with a spare working key or as complicated as OBD2 or EEPROM programming.
The majority of US and Asian auto manufacturers use the same programming protocols as auto tool makers, which means they can develop hardware or software for automotive locksmiths.
Transponder Chips
Transponder chips are in many newer cars to prevent car theft. These are tiny computer microchips that emit radio waves at a low level. They are equipped with a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle isn't able to recognize the signal, the engine will be shut down. This technology has been an enormous success in preventing theft of cars. This technology has also helped car owners save a good deal of money since they don't have to buy new vehicles.
The transponder system's basic idea is to make it difficult for thieves to start your vehicle without the correct key. In the past, car thieves used an ordinary screwdriver to force the ignition switch of your vehicle into "on" mode or even hot-wire it to evade the system. These kinds of thefts have been drastically reduced with the introduction of the transponder chip.
When you insert a transponder keys into the ignition, it will transmit an electrical signal that is picked up by a hidden antenna that is positioned around the barrel of the ignition. This antenna is programmed to read the specific frequency of the chip inside the key. The computer onboard of the car will then recognise the key as being valid and allow fuel flow and power the starter to begin the engine.
Based on the manufacturer, some vehicles will only recognise certain types of transponder chip. It is therefore important that your automotive locksmith is equipped with the correct equipment to program your keys and remotes for your vehicle.
A reputable locksmith for automotive needs to have a multi-vehicle key programming tool that works with different models and car brands. This is a cheaper option than buying specific tools for each model of vehicle. These aren't as popular however, there are specialist automotive key programmers that are able to only work on a specific type of vehicle. The top automotive locksmiths have the tools needed to work on any vehicle. Make sure you choose an established company that has this type of equipment.
Key FOBs
Key FOBs are programmeable transponder chips that allow your vehicle to open doors and start the engine with the push of a button ignition. They also have buttons you can press to trigger features like door locks, trunk release or control of the fuel flap. Certain fobs can be controlled with the press of buttons. For instance an "smart key" which allows you to summon your car to tight parking spaces, like the Genesis GV60 or a Tesla or Genesis GV60.
You can program spare key fobs by yourself with the help from an instruction manual, however you'll need to contact an automotive locksmith in the event that yours has stopped working. This is because a professional locksmith has the specialized equipment and access to the programming tools needed to connect your car's computer via the OBD (OBD) port located beneath the steering wheel.
The majority of key fobs come with security features that make it harder for attackers duplicate and copy the signals that they transmit. They include pseudo-random generators that generate a new unlock code every time you press the button on the key fob. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In most cases you can buy an additional key fob at the dealership or another retailer and then have it programmed by a locksmith for your vehicle to fit your specific vehicle. This is because the majority of major US and Asian automakers have key-fob programming protocols 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 all vehicles, most automotive locksmiths do not recommend using them as they are likely to function poorly or not at all. Instead, they suggest purchasing fobs specifically designed for your vehicle so that you can be sure they'll work properly and are less prone to issues such as interfering or incompatibility. This will save you money over the long term by avoiding costly repairs or replacing the fobs.
Vehicle Manufacturers' Programming Tools
The automotive industry has made great advancements in the past few decades. Nowadays, cars are computer-driven. One of the most important components of this technology is a transponder chipset that must be programmed into the vehicle by a locksmith or dealer/mechanic in order to function. Key fobs come with built-in security features that will prevent hot-wiring (like in a movie) and the car won't start if it doesn't have the correct key.
Key fobs are slightly more complicated than a traditional mechanical key. This is why they are placed in the hands of experienced, professional auto locksmiths. The cost of a key fob may vary based on the vehicle model and the key type, but they typically run between $85 to $400. This includes programming car key labor costs to program the keyfob, as well as any replacement parts.
These car key fobs are more complex because they utilize an operating system that communicates with the computer onboard of the car. The software blocks access by unauthorised persons by only permitting keys that have been programmed specifically for a particular car to work. This means that if your keys replaced, you'll need have the new key fob programed to the car to function.
This is done by using a programing tool for car keys that is compatible with the brand of your vehicle. This tool permits a locksmith to connect to the OBD port in the vehicle, and then enter the programming mode. The key programming device could be an handheld device that is inexpensive or one that is extravagant and can do more than just program keys (like reading the eeprom files in the ECU).
While some people may attempt to program their own keys with these tools, this is an activity best left to a professional auto locksmith. If you're not familiar with the details of the various software systems, it's easy to accidentally alter settings that could damage the vehicle. It's important to keep in mind that a professional with experience will assist you in avoiding these issues.
On-Board Programming
If your car is old enough, it may still come with a key made of steel that you can use to unlock doors and turn off the ignition. Modern cars come with a transponder that must be acknowledged and accepted by the computer system before it can start. This is an additional layer of security to keep thieves from starting and driving away with a stolen car. A locksmith who is certified has the tools and software required to create a key that will be compatible with your car's security system.
Your locksmith will have to obtain a blank key that is compatible with the vehicle's make and model. Once your locksmith has the key, he will connect the programming scanner to the diagnostic port of your vehicle. This will place the car in a special programming mode, which will allow the locksmiths to add a key to the system.
To do this, the key programming scanner will communicate with the car's computer system to transmit an exact code. The computer will recognize this code and include it into the list of keys that are authorized. In some instances, the scanner will also be able to delete keys that are stolen or lost from the system.
You can also program new keys by using EEPROM. It is more complex and requires a thorough understanding of electronic systems. It is best to delegate it to a professional with expertise with these systems.
Onboard programming is the quickest way for a locksmith to program the new key. If everything is done properly it could take as little as one minute. If the key isn't in the correct state or the procedure isn't adhered to, it could take as long as a half hour.
There are a variety of key programmer scanners which can work with different makes and models of vehicles. Both the Smart Pro and Autel IM608 Pro have become extremely popular with locksmiths due to their wide range of models for vehicles. There is no system that can program every vehicle. Furthermore, these systems are expensive. It's a good idea purchase a computer that will get regular updates as the manufacturer releases new technologies. In the event that your machine is not updated, it will become obsolete quickly.
