Automotive Locksmith Key Programming
The majority of modern cars require some form of key programming. Depending on your vehicle's model and manufacturer, the process may be as simple as using a spare key to program the onboard computer, or as complicated as EEPROM or OBD2 programming.
Most US and Asian car manufacturers share their programming protocols with auto tool makers to allow them to develop tools and hardware for locksmiths in the automotive industry to use.
Transponder Chips
Transponder chips are used in many newer cars to guard against theft of vehicles. These are small computer microchips which emit radio signals of low-level. They have a unique digital serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your car doesn't recognise the signal it will shut down the engine. This technology has been extremely successful in preventing car theft. This technology has also helped car owners save a huge amount of money since they don't have to purchase new cars.
The principle behind the transponder system is to make it impossible for thieves to open the doors of your car without the proper key. In the past, thieves used an ordinary screwdriver to force the ignition switch of your vehicle into "on" mode or even hot-wire it in order to bypass the system. These kinds of thefts have drastically reduced thanks to the introduction of the transponder chip.
When you place the transponder key into the ignition the signal is received by an antenna that is concealed around the barrel. This antenna is programmed to read the specific frequency of the chip inside the key. The car's onboard computer will then recognize that the key is legitimate and allow fuel to flow, power up the starter, or even begin it.
Some vehicles only recognize specific type of transponder chip depending on the manufacturer. This is why it's crucial to make sure that your locksmith in the automotive industry has the right equipment to program your car's keys and fobs properly.
A good automotive locksmith should have a multi-vehicle key programming tool that can work on many different models and manufacturers of cars. This is a cheaper solution than buying specific tools for each type of vehicle. They are not as common however, there are specialist automotive key programmers that are able to only work on a particular brand of vehicle. The top automotive locksmiths are equipped to work on any vehicle. Be sure to choose a reputable firm that has this type of equipment.
Key FOBs
Key FOBs are programmable transponder chips that allow your vehicle to open doors and begin the engine with the push of a button ignition. They also have buttons that you can press to activate features such as trunk release, door locks or control of the fuel flap. Certain fobs can be controlled using buttons. For example an "smart key" that allows you summon your car to parking spaces, such as a Tesla or Genesis GV60.
While some replacement keys can be programmed by you using the aid of a user's guide but you'll usually require an automotive locksmith to get a brand new one programmed in case yours stops functioning. This is because a professional locksmith has the equipment that is specialized and access to the tools for programming needed to connect your car's computer via the OBD (OBD) port located beneath the steering wheel.
Most key fobs today include security features that make it difficult for attackers to duplicate or duplicate the signals they transmit. They include pseudo-random sequence generators that generate a fresh unlock code each time you press the key fob's button. This is to prevent attackers from capturing and playing back the unlock signal in order to gain access to your vehicle.
In many instances you can buy an alternative key fob from the dealer or other retailer and have it programmable by your locksmith in your car to fit your specific vehicle. This is because most of the major US and Asian car manufacturers use key fob programming protocols with third-party firms that make the tools that auto locksmiths employ to program keys for their customers.
Certain key fobs from the aftermarket may be advertised as being compatible with vehicles of all kinds. However, professional locksmiths recommend against using them because they are likely to work poorly or not at all. Instead, they suggest purchasing fobs specifically designed for your vehicle, so that you are certain they'll function properly and be less prone to issues such as interfering or incompatibility. This will save money over time by avoiding costly repairs or replacements of your fobs.
Vehicle Manufacturers' Programming Tools
Automotive technology has come a long way, and today's vehicles require computer technology to function. One key element of this technology is a transponder chip that needs to be programmed to the vehicle by a locksmith or dealer/mechanic in order to work. These key fobs are equipped with security features to prevent hot-wiring like in a film. The car won't start without the correct keys.
These key fobs can be a little more complex than a standard mechanical key. This is why they are placed in the hands of experienced professional auto locksmiths. The cost of a key fob may vary depending on fob key programming the car model and the key type, but they typically run between $85 and $400. This includes the cost of labor to program the keyfob, as well as any replacement parts.
To complicate the process the car key fobs use a special software system to work with the car's onboard computer. The software blocks unauthorized access by allowing the key to function if it has been programmed to that specific car. If you decide to replace your keys, you will need to program the new key fob into the car in order for it to work.
This is accomplished using a programing tool for keys for cars that are compatible with your vehicle's brand. This tool allows the locksmith to connect to the OBD port (OBD) in the vehicle and then enter the programming mode. Key programming devices can be an handheld device that is affordable or fancy and can do more than just programming keys (like reading the eeprom file in the ECU).
While some may try to program their own keys using these tools, this is a job best left to a professional auto locksmith. It's easy to make mistakes using the software systems if you don't understand the nuances. This could result in damage. It's important to keep in mind that an experienced professional will help you avoid these problems.
On-Board Programming
If your car is of a certain age, you'll still have a key from the past that you can use to open the doors and turn on the ignition. Modern cars come with a transponder chip that must be recognized by the car's computer system to allow it to start. This adds another layer of security to keep thieves from starting and driving away with a stolen car. A locksmith certified will have the tools and software required to create a key that will work in your car's system.
Your locksmith will need to purchase an uncut key that is that is compatible with the vehicle's model and make. Once the key is in hand, your locksmith will link the programming scanner to the diagnostic port of your car. This will place the car into a special programing mode, which will allow locksmiths to add keys to the system.
The key programmer scanner communicates with the computer in the vehicle to send the code. The computer will be able to recognize the code and add it to the list of keys that are approved. In certain instances, the scanner will also be able to erase keys that have been stolen or lost from the system.
You can also program new keys using EEPROM. It is more complex and requires a deep understanding of how electronic systems operate. This is why it should be left to a professional who has extensive experience working with these kinds of systems.
Locksmiths can program a key quickly with onboard programming. It can take as little as a minute when everything is executed correctly. If the key isn't in good working order or the procedure isn't followed exactly, the process can take up to half an hour.
There are many key programmer scanners on the market that work with various car models and makes. The Smart Pro and the Autel IM608 Pro are both extremely popular with locksmiths since they cover a wide range of vehicle models. The system cannot program every vehicle. Furthermore, these systems are quite expensive. It is a good idea to buy a programmer that will get regular updates as the manufacturer releases new technologies. If not, your computer will be obsolete in a short time.
