Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Depending on the car's maker and model, the process can be as easy as onboard programming with an extra working key or as complex as EEPROM or OBD2 programming.
The majority of US and Asian automobile manufacturers use the same programming protocols as auto tool makers so that they can develop hardware and software for locksmiths working in automotive vehicles.
Transponder Chips
Most modern cars are equipped with transponder chips to prevent car theft. These are tiny computer microchips which emit radio waves at a low level. They have 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 and the engine is shut down. This technology has been an incredible success in preventing auto theft. This technology has also helped car owners save a good deal of money since they don't have to purchase new cars.
The basic idea behind the transponder system is to make it difficult for thieves to get into your car without a key. In the past, car thieves would simply push your car's ignition switch into the "on" position using a flat screwdriver or even hot-wire the car to bypass the system entirely. Transponder chips have dramatically reduced these types of thefts.
When you place the transponder key in the ignition, the signal is received by an antenna hidden around the barrel. This antenna is programmed so that it can detect the particular frequency of the chip inside the key. The onboard computer in the car will recognize the key as being valid and will allow fuel flow and power the starter to begin the engine.
Depending on the manufacturer, certain vehicles can only recognize a specific type of transponder chip. This is why it is essential to ensure that your locksmith in the automotive industry has the appropriate equipment to program your car's keys and fobs correctly.
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. There are also specific key programming tools for automobiles that can only be used on specific models of vehicles however, they are less popular. The best locksmiths for automotive have the tools to work on any vehicle. Make sure you choose a reputable firm that has this type of equipment.
Key FOBs
The name implies that key FOBs house the transponder chips that can be programmed to allow your vehicle to identify and unlock the doors or start the engine with a push-button ignition. You can also use the buttons to trigger features such as trunk releases, door locks or controls for the fuel flap. Some fobs can be controlled with the press of buttons. For instance, a "smart key" which allows you to summon your car to tight parking spaces, like the Genesis GV60 or a Tesla or Genesis GV60.
While some replacement keys can be programmed with the assistance of a user's manual, you'll often require an auto locksmith to get a new one programmed if the one you have isn't working. A professional locksmith is better equipped to connect the computer of your vehicle to the OBD port located under the steering wheel.
The majority of key fobs come with security features to make it harder for attackers replicate and clone the signals they transmit. Certain key fobs feature pseudo-random code generators, which generate a different unlock code every time you press the button. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In certain instances you can purchase an alternative keyfob from an authorized dealer or another retailer. Your locksmith at your auto will then program it to work with your vehicle. This is because the majority of major US and Asian auto manufacturers use the same key-fob programming protocol with third-party companies that make the tools used by locksmiths for programming their customer's keys.
Certain aftermarket key fobs can be marketed as being compatible with all vehicles. However, automotive locksmiths recommend against using them because they are likely to work poorly or not work even work at all. They recommend buying fobs made specifically for your vehicle to ensure they work correctly and are less prone to issues such as interference or incompatibility. This will save you money over time, as you avoid costly repairs or replacements for your fobs.
Tools for programming vehicles used by manufacturers
The automotive industry has come a long way, and today's vehicles require computer technology in order to function. One key element of this technology is a transponder chip that must be programmed into the vehicle by a locksmith or dealer/mechanic in order to work. Key fobs come with built-in security features that stop hot-wiring (like in a film) and the car won't start without the correct key.
Key fobs can be somewhat more complicated than a standard mechanical key. This is why they are usually placed in the hands of experienced, professional auto locksmiths. The cost of a key fob may differ based on the vehicle model and the key type however they usually cost between $85 and $400. This includes the cost of labor to program the key fob as well as the cost of any needed replacement parts.
Car key fobs are more complicated because they use an operating system that communicates with the onboard computer of the car. The software blocks access to unauthorized users by allowing the key to function only if it's been programmed to the car in question. This means that if your keys replaced, you'll have to have the new key fob programed to the car in order for it to function.
This is accomplished using a programing tool for car keys that is compatible with the brand of your vehicle. This tool lets the locksmith connect to the OBD port (OBD) in the vehicle and then enter an programming mode. The key programming tool can be a handheld device that is inexpensive device or a more expensive one that is capable of performing many things that go beyond key programming (like reading and cloning the Eeprom files within the ECU).
Although some people might attempt to program their own keys using these tools, this is a job best left to an experienced auto locksmith. It's easy to make mistakes when using software systems if you don't understand the nuances. This can lead to damage. 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 old enough that it has a key, it might still come with a key made of steel that you can use to open doors and turn 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 extra layer of security that stops car thieves from stealing a car and driving off with the car. A locksmith who is certified will have the right tools and software to program a new key that works with your car's security system.
Your locksmith will first need to obtain an uncut key that is compatible with your vehicle's make and model. Once your locksmith has the key, he'll connect the programming scanner to the diagnostic port of your vehicle. This will put the vehicle into a special programming mode which will allow the locksmith to add a new key into the system.
To do this, the key programmer scanner will communicate with the car's computer and send an exact code. The computer will recognize the code and add it to the list of keys approved by. In some instances the scanner will also delete lost or stolen keys.
You can also program new keys with the EEPROM. It is more complicated and requires a thorough understanding of electronic systems. This is why it should be left to a professional who has a lot of expertise working on these types of systems.
Locksmiths can program a key quickly using onboard programming. When everything is done correctly it could take just one minute. If the key is not in the right condition or the procedure isn't followed exactly, the process could take as long as a half hour.
There are a variety of key programmer scanners available that work with various vehicle models and makes. Both the Smart Pro and Autel IM608 Pro have become very popular with locksmiths due to their wide range of models for vehicles. The system cannot program every vehicle. Furthermore, these systems cost a lot. It's best to purchase one that will receive regular updates from the manufacturer as new technologies are released. Your computer's programming software will soon become obsolete if you do not take this step.
