Automotive Locksmith Key Programming
Modern cars need some type of key programming. Depending on the vehicle's make and model, the procedure can be as easy as onboard programming with a spare key that works or as complicated as OBD2 or EEPROM programming.
The majority of US and Asian auto manufacturers have a programming protocol that they share with auto tool makers, so they can develop tools or hardware for automotive locksmiths.
Transponder Chips
Most modern cars are equipped with what are called transponder chips in order to prevent theft. These are microchips in the form of computers which emit radio signals of low-level. The microchips are equipped with a unique serial number which authenticates your keys when you insert it into the ignition barrel. If your car isn't able to recognize the signal, it will shut down the engine. This technology has been an immense success in stopping auto theft. This technology has also saved car owners a great deal of money by not having to purchase new cars.
The basic concept behind the transponder system is to make it hard for thieves to get into your vehicle without the correct key. In the past, thieves would simply push your ignition switch to the "on" position using a flat screwdriver or even use hot wires to disable the system completely. These kinds of thefts have been dramatically reduced with the introduction of the transponder chip.
When you insert a transponder key into the ignition, it transmits a signal that is picked up by a hidden antenna that is positioned around the barrel of the ignition. The antenna is programmed to read the specific frequency of the chip within the key. The car's onboard computer will detect that the key is genuine and allow the fuel to flow, then power up the starter, or even start it.
Some vehicles only recognize a certain type of transponder chips according to the manufacturer. This is why it's crucial to make sure that your automotive locksmith is equipped to program your car's key and fobs correctly.
A good automotive locksmith will possess a multi-vehicle programing tool that can be used with different automobile models and manufacturers. This is a cheaper option than purchasing separate tools for each brand of vehicle. These are less common however, there are specialist automotive key programmers that can only work on a particular model of vehicle. The best locksmiths for automotive are equipped to work on any vehicle. Be sure to choose an established company that has this type of equipment.
Key FOBs
Key FOBs are programmable transponder chip devices that permit your vehicle to unlock doors and begin the engine with the push of a button ignition. You can also press buttons to activate features such as door locks, trunk releases or controls for the fuel flap. Certain fobs come with additional functions that can be controlled using the press of a button for example, the "smart" key fob that allows you to get your car into tight parking spots as you would with a Tesla or Genesis GV60.
While certain replacement key fobs can be programmed with the help of a user manual but you'll usually require an auto locksmith to get a new one programmed in case yours stops working. A professional locksmith is more equipped to connect your computer to the car via the OBD port under the steering wheel.
Today, most key fobs have 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 new unlock code every time you press the button on your key fob. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In certain instances, you can buy 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 auto manufacturers use the same key-fob programming protocol with third-party companies that create the tools used by locksmiths who program their customers' keys.
While some aftermarket key fobs are marketed as being compatible with any vehicle, most automotive locksmiths do not recommend using them as they will likely only work poorly or not at all. They recommend buying fobs made specifically for your vehicle so that they work correctly and are less susceptible to issues such as interference or incompatibility. This will save money over time by avoiding costly repairs or replacements for your fobs.
Tool for Programming Vehicle Manufacturers'
Automotive technologies have progressed a lot and today's vehicles need computer technology in order to function. A transponder chip is an important part of this technology. It has to be programmed by a locksmith mechanic or dealer to function. Key fobs come with built-in security features that stop hot-wiring (like in a film) and the car will not start if you don't have the proper key.
Key fobs are somewhat more complicated than a conventional mechanical key. This is why they are usually handled by experienced professional auto locksmiths. The cost of a car key fob varies depending on the type and model of key, but it is generally between $85 to $400. This includes the labor cost to program the keyfob, as well as any replacement parts.
To complicate the process the car key fobs use a special software system to connect to the car's onboard computer. The software blocks unauthorized access by only allowing the key to operate only if it's programmed for the specific car. This means that if you get your keys replaced, you'll have to have the new key fob programmed to the car to function.
The most popular method to do this is by using a car key programming tool that is compatible with the model of the vehicle. This tool allows a locksmith to connect to the OBD port in the vehicle and then enter the programming mode. The key programming device can be a handheld device that is inexpensive or one that is fancy and can do more than just programming keys (like reading the eeprom files in the ECU).
While some people may attempt to program their own keys with these tools, this is a job best left to an experienced auto locksmith. If you're not aware of all the details of the various software systems, it's easy to make a mistake and alter settings that could potentially 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 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 off the ignition. However, modern cars have a transponder chip that must be recognized by the computer system of the car in order to start. This adds an extra layer of security that stops car thieves from starting a car stolen and then driving off with it. A locksmith certified will have the tools and software needed to create a key that will be compatible with your car's security system.
Your locksmith will first need to acquire 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 put the vehicle into an exclusive programming mode that will allow the locksmith to add a new key into the system.
To accomplish this, the key programming scanner will communicate with the car's computer to send an exact code. The computer will detect the code and add it into the list of approved key. In some cases the scanner may 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 a thorough understanding of electronic systems. This is why it's best left to a professional that has extensive experience working with these kinds of systems.
Onboard programming is the most efficient method for locksmiths to program an entirely new key. It can take as little as one minute if everything is executed correctly. If the key isn't in the right condition or the procedure isn't followed exactly, the process could take up to half an hour.
There are numerous key website programmer scanners that support various models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro are very popular among locksmiths due to their wide selection of vehicle models. The system cannot program every vehicle. In addition, these machines cost a lot. It's best to purchase a programmer which will receive regular updates from the manufacturer as new technologies are developed. If not, your computer will soon become obsolete.
