Automotive Locksmith Key Programming
Modern cars need some kind of key programming. Based on the car's make and model, the procedure can be as easy as onboard programming with an extra working key or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian car makers use the same programming protocols as auto tool manufacturers in order to create software and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Most modern cars are equipped with what are called transponder chips in order to prevent theft. These are tiny computer microchips that emit low-level radio waves. 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 car doesn't recognise the signal it will stop the engine. This technology has proven to be an enormous success in preventing car theft. This technology has also helped car owners save a good amount of money as they do not have to purchase new cars.
The basic idea behind the transponder system is to make it difficult for thieves to open the doors of your car without the proper key. In the past, car thieves would use the flat screwdriver to push the ignition switch of your car into "on" mode, or hot-wire it in order to get around the system. These types of thefts have drastically reduced thanks to the introduction of the transponder chip.
When you insert the transponder key in the ignition the signal is received by an antenna hidden around the barrel. The antenna is programmed to read the specific frequency of the chip inside the key. The onboard computer in the car will recognize the key as being valid and allow fuel flow and start the starter. begin the engine.
Depending on the manufacturer, some vehicles will only recognise a specific type of transponder chip. It is therefore important that your locksmith for cars is equipped with the right equipment to program your keys and remotes for your vehicle.
A good automotive locksmith should have a multi-vehicle key programming device that works with different models and manufacturers of cars. This is a much more cost-effective approach than purchasing individual tools for each brand of vehicle. There are also specially-designed key programming devices for automotive that are only suitable for specific brands of vehicles, but these are less popular. The best automotive locksmiths will have the right tools to work on any type of vehicle, so make sure you find a reputable company with these kinds of tools.
Key FOBs
As the name implies, key FOBs contain transponder chips that can be programmed to allow your car to recognize and unlock the doors or start the engine with a push-button ignition. It is also possible to press buttons to activate features like door locks, trunk releases or fuel flap controls. Certain fobs come with additional functions that can be controlled with the push of a button, such as the "smart" key fob that lets you get your car into parking spaces that are difficult to access as you would with a Tesla or Genesis GV60.
While some replacement key fobs can be programmed by you with the assistance of a user's manual however, you'll typically require an auto locksmith to get a brand new one programmed if yours stops functioning. A professional locksmith is better equipped to connect the computer of your car via the OBD port on 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 come with pseudo-random code generators which generate a new unlock code every time you press the button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In many instances, you can purchase an alternative key fob from the dealer or other retailer and have it programmed by a locksmith for your vehicle to fit your specific vehicle. This is because the majority of major US and Asian auto manufacturers share their key-fob programming protocols with third-party companies that produce the tools used by locksmiths for programming their customers' keys.
While some aftermarket key fobs are marketed as being compatible with all vehicles, most automotive locksmiths don't recommend using them because they are likely to function poorly or not at all. Instead, they suggest buying fobs that are specifically made for your specific vehicle so that you are certain they'll function properly and be less prone to issues such as interfering or incompatibility. This will save you money in the end by avoiding costly repairs or replacing the fobs.
Vehicle Manufacturers' Programming Tools
The automotive industry has made huge advances in the last couple of decades. Nowadays, cars are computer-driven. A transponder chip is an essential part of this technology. It has to be programmed by a locksmith, mechanic or dealer to function. These key fobs have built-in security features that prevent hot-wiring (like in a film) and the car won't start without the right key.
These key fobs are a little more complicated than a mechanical keys and that's why you'll usually find them in the hands of an expert professional auto locksmith. The cost of the car key fob is dependent on the type and model of key, but it is generally between $85 to $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 only allowing the key to operate only if it's been programmed to that specific car. This means that if you get your keys replaced, you'll have to have the new key fob programmed to the car for it to work.
This is done by using a tool for programming car key s that is compatible with your vehicle's brand. This tool allows a locksmith to connect to the OBD port on the vehicle and then enter programming mode. The key programming tool could be a simple handheld device or a fancy one that is capable of performing many things that go beyond key programming (like reading and cloning Eeprom files within the ECU).
Although some people might attempt to program their own keys using these tools, it's something best left to an experienced auto locksmith. Unless you're familiar with all the aspects of the various software systems, it's very easy to make a mistake and alter settings that could potentially damage the vehicle. It's important to remember that a professional with experience will help you avoid these problems.
On-Board Programming
If your car is old enough that you'll have a traditional key made of metal that you can use to open the doors and turn on the ignition. Modern cars come with transponders that need to be acknowledged and accepted by the computer system in order to start. This is an additional layer of protection that can stop car thieves from starting a stolen car and driving away with the car. A licensed locksmith has the tools and software to create a key that is compatible with the security system in your car.
First, your locksmith will need to get a blank key that is compatible with the make and model of your car. Once the key is in your possession, your locksmith will link the scanner that is used for programming to your car's diagnostic port. This will place the car into a special programing mode, which will allow locksmiths to add keys to the system.
To accomplish this, the key programming scanner will communicate with the car's computer to send a specific code. The computer will be able to recognize the code and add it to the list of approved keys. In some instances scanners can remove keys that have been stolen or lost.
You can also program new keys with 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 expertise working on these types of systems.
Locksmiths can program keys quickly using onboard programming. If everything is done properly it could take just one minute. However, if the key isn't placed in the proper condition or the procedure isn't followed exactly, it can take up to an hour.
There are a variety of key programmer scanners that support different makes and models of vehicles. Both the Smart Pro and Autel IM608 Pro have become very popular with locksmiths due to their wide range of vehicle models. However, neither will be able to program every vehicle in existence. These devices are also expensive. It's a good idea purchase a computer that is updated regularly as the manufacturer releases new technologies. If not, your computer will become obsolete quickly.
