Automotive Locksmith Key Programming
The majority of modern cars require some kind of key programming. Based on the model and make the process could be as simple as using an extra key to programme the computer onboard, or as complicated as OBD2 programming or EEPROM.
Most US and Asian auto manufacturers have a programming protocol that they share with auto tool manufacturers, so they can create hardware or software for locksmiths in the automotive industry.
Transponder Chips
The majority of newer cars have transponder chips in order to prevent theft. These are microchips in the form of computers that emit radio signals at a low level. The microchips have an unique serial number that authenticates your key whenever you plug it into the ignition barrel. If your vehicle doesn't recognize the signal, the engine will be shut down. This technology has proven to be an immense success in stopping auto theft. This technology has also helped car owners save a good deal of money by not having to purchase new cars.
The basic idea behind the transponder system is to make it difficult for thieves to get into your vehicle without a valid key. In the past, car thieves would force your car's ignition switch into the "on" position using an ordinary screwdriver or hot-wire the car to bypass the system completely. Transponder chips have drastically decreased the likelihood of theft.
When you insert a transponder key into the ignition, it will send the signal which is picked up by a hidden antenna circling the barrel of the ignition. The antenna is programmed to detect the particular frequency of the chip within the key. The car's onboard computer will detect that the key is valid and allow fuel to flow, turn up the starter, or even start it.
Depending on the manufacturer certain vehicles can only recognize a specific type of transponder chip. This is why it is important to ensure that your locksmith for automotive has the right equipment to program your car's key and fobs properly.
A good automotive locksmith should have a multi-vehicle key programming device that works with different car manufacturers and models. This is a much cheaper alternative than buying separate tools for each type of vehicle. These aren't as popular, but there are specialised automotive key programmers that are able to only work on a specific model of vehicle. The best automotive locksmiths are equipped to work on any vehicle. Make sure you choose a reliable company that is equipped with this type of equipment.
Key FOBs
As the name implies, key FOBs house the programmable transponder chips that enable your vehicle to identify and unlock the doors, or start the engine using push-button ignition. They also have buttons you can press to trigger features like trunk release, door locks or control of the fuel flap. reprogramming keys for cars have additional functions that can be controlled with the button presses like a "smart" key fob that lets you get your car to parking spots that are tight, like you would with the Genesis GV60, Tesla or Genesis GV60.
While some replacement keys can be programmed with the aid of a user's guide but you'll usually require an auto locksmith to get a brand new one programmed in case yours stops working. A professional locksmith is better equipped to connect the computer of your vehicle via the OBD port under the steering wheel.
Most key fobs today come with security features that make it difficult for criminals to duplicate or copy the signals they transmit. Certain key fobs feature pseudo-random code generators, which generate a new unlock code each time you press the button. This prevents attackers capturing and replaying the unlock signal to gain access to your car.
In some cases you can purchase the replacement keyfob at 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 automakers have key-fob programming protocols with third-party companies that make the tools used by locksmiths for programming their customers' keys.
Certain key fobs from the aftermarket may be marketed as compatible with any vehicle. However, automotive locksmiths recommend against using them because they're likely to function poorly or not at all. Instead, they suggest buying fobs designed specifically for your specific vehicle so that you are certain they'll function properly and be less susceptible to issues like interfering or not working. This will save you money in the long run by avoiding costly repairs or replacements for your fobs.
Tool for Programming Vehicle Manufacturers'
Automotive technologies have come a long way and modern vehicles require computer technology to function. Transponder chips are an essential component of this technology. It must be programmed by a locksmith, mechanic, or dealer to work. Key fobs are fitted with security features to stop hot-wiring, as in a movie. The car will not start without the correct keys.
These key fobs can be slightly more complicated than a conventional mechanical key. This is why they're usually placed in the hands of experienced, professional auto locksmiths. The cost of a car key fob varies according to the type and model of key, but is typically between $85 to $400. This includes the cost of labor to program the key fob and the costs for any required replacement parts.
To make the process more difficult, these car key fobs utilize a specific software system to connect to the car's onboard computer. The software prevents unauthorized access by only permitting the key to function only if it's programmed to the car in question. If you change your keys, you'll need to program the new key fob in the car in order for it to work.
This is accomplished by using a programming tool for car keys that is compatible with your vehicle's brand. This tool lets the locksmith connect to the onboard diagnostics port (OBD) within the vehicle and then enter the programming mode. Key programming tools can be a handheld device that is inexpensive device or a more expensive one that can perform many things that go beyond key programming (like reading and cloning EEEPROM files in the ECU).
While some may try to program their own keys using these tools, it's a job best left to a professional auto locksmith. If you're not aware of all the aspects of the various software systems, it's possible to make a mistake and alter settings that could damage the vehicle. It's important to keep in mind that a professional with experience will help you avoid these issues.
On-Board programming
If your car is older than you that you'll have a traditional metal key to use to unlock the doors and turn on the ignition. Modern cars come with transponders that need to be recognized and accepted by the computer system in order to start. This is an additional layer of security that stops car thieves from stealing a car and then driving off with it. A licensed locksmith will have the right tools and software to program a new key that is compatible with the security system of your vehicle.
First, your locksmith needs to purchase a blank key that is compatible with the model and make of your car. Once your locksmith has the key, he will connect the scanner for programming to the diagnostic port of your vehicle. This will put your car into an exclusive programming mode which will allow the locksmith to add a new key to the system.
The key scanner that is programmed communicates with the computer in the vehicle to transmit an electronic code. The computer will be able to recognize the code and add it to the list of approved keys. In some instances, a scanner can also remove keys that have been stolen or lost.
The EEPROM programming method is a different one that can be used to program new car keys. It is more complex and requires an in-depth understanding of how electronic systems work. This is why it's best left to a professional who has years of experience working on these types of systems.
Onboard programming is the quickest way for a locksmith to program the new key. If everything is done correctly, it can take as little as one minute. If the key is not in the right condition or the procedure isn't being followed exactly, the process could take as long as a half hour.
There are numerous key programmer scanners which can work with different models and makes of vehicles. The Smart Pro and the Autel IM608 Pro are both extremely popular amongst locksmiths because they cover a wide range of vehicles. The system cannot program every vehicle. These machines are also quite expensive. It's a good idea purchase a programer that receives regular updates as the manufacturer releases new technologies. Your programming machine will quickly become obsolete if you don't do this.
