Automotive Locksmith Key Programming
Most modern-day cars require some kind of key programming. Based on the car's make and model, the process can be as easy as onboard programming using an extra working key or as complicated as EEPROM or OBD2 programming.
Most US and Asian auto manufacturers use the same programming protocols as auto tool manufacturers, so they can develop hardware or software for locksmiths in the automotive industry.
Transponder Chips
Transponder chips are used in many newer cars to stop theft of cars. These are tiny computer microchips that emit radio waves of low-level. They are equipped with a unique digital serial number that authenticates the key to your vehicle when it is plugged into 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. It has also saved many car owners a significant amount of money because they don't have to replace their vehicles.
The basic concept behind the transponder system is to make it difficult for thieves to get into your vehicle without a valid key. In the past, thieves would use a flat screwdriver to force the ignition switch of your car into "on" mode or even hot-wire it in order to evade the system. 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 will transmit the signal which is received 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 computer onboard will detect that the key is valid and allow fuel to flow, turn the starter or begin it.
Some vehicles only recognize a certain type of transponder chip, depending on the manufacturer. This is why it's essential to ensure that your locksmith in the automotive industry is equipped to program your car's keys and fobs correctly.
A good automotive locksmith should have a multi-vehicle key programming device that can work on many different car manufacturers and models. This is a less expensive solution than buying separate tools for each brand of vehicle. There are also specific key programming devices for automotive that can only be used on specific brands of vehicles however they are not as popular. The best automotive locksmiths will have the right tools to deal with any kind of vehicle, so ensure you choose a reputable business that offers these types of tools.
Key FOBs
The key FOBs are programmable transponder chip devices that allow your vehicle to unlock doors and start the engine with a push button ignition. They also have buttons you can push to activate features like trunk release, door locks or fuel flap control. Some fobs can be controlled using buttons. For example an "smart key" which allows you to summon your car to tight parking spaces, like a Tesla or Genesis GV60.
While some replacement keys can be programmed by you using the help of a user manual but you'll usually require an automotive locksmith to have a new one programmed if yours stops working. A professional is better equipped to connect the computer of your vehicle to the OBD port under the steering wheel.
The majority of key fobs are equipped with security features to make it difficult for attackers to duplicate and copy the signals that they transmit. Certain key fobs come with pseudo-random code generators that 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 many instances, you can purchase an alternative key fob from the dealership or another retailer and have it programmed by your automotive locksmith to fit your specific vehicle. This is because the majority of major US and Asian automakers have key-fob programming protocols with the third-party companies who create the tools used by locksmiths for programming their customer's keys.
Certain aftermarket key fobs can be advertised as being compatible with vehicles of all kinds. However, locksmiths for automotive advise against using them since they're more likely to perform poorly or not work at all. They suggest purchasing fobs that are designed specifically for your vehicle so that they will work properly and are less prone to issues such as interference or incompatibility. This will save you money in the end by avoiding expensive repairs or replacing your fobs.
Vehicle Manufacturers' Programming Tools
The automotive industry has made great advances in the last couple of decades. Today's cars are computer-driven. One of the most important components of this technology is a transponder chip that requires to be programmed to the vehicle by a locksmith or dealer/mechanic in order to function. Key fobs come with built-in security features that will prevent hot-wiring (like in a film) and the car will not start if you don't have the correct key.
Key fobs can be slightly more complicated than a standard mechanical key. This is why they are placed in the hands of experienced professional auto locksmiths. The cost of a car key fob varies depending on the type and model of key, but it is typically between $85 to $400. This includes the labor required to program the key fob as well as the cost of any needed replacement parts.
To make the process more difficult to make the process more complicated, these key fobs for cars make use of a special software to work with the car's onboard computer. The software prevents unauthorised access by only permitting keys that have been programmed for a specific car to work. This means that if you get your keys replaced, you'll need to have the new key fob programed to the car in order for it to work.
The most common method to do this is by using an auto key programming tool that is compatible with the brand of the vehicle. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) within the vehicle and then enter the programming mode. The key programming device can be an handheld device that is inexpensive or one that is extravagant and can do more than just program keys (like reading the eeprom file in the ECU).
Some people try to program their keys by themselves using these tools. However, this is best left to an expert auto locksmith. If you're not aware of all the ins and outs of the various software systems, it's very easy to accidentally alter settings that could potentially damage the vehicle. The most important thing to keep in mind is that an experienced professional can help you avoid these issues.
On-Board programming
If your vehicle is old enough to be considered old-fashioned, you'll have a traditional key made of metal that you can use to open the doors and turn on the ignition. However, modern vehicles have transponder chips that must be recognized by the car's computer system in order to start. This is an additional layer of security that prevents car thieves from starting a stolen car and then driving off with the car. A locksmith certified will have the tools and software required to create a key that will be compatible with your car's security system.
The locksmith needs to purchase an uncut key that is compatible with the model and make of your vehicle. Once the key is received the locksmith will connect the scanner for programming to the diagnostic port of your car. This will place the car into a special programing mode, which allows locksmiths to connect keys to the system.
To accomplish this, the key programming scanner will communicate with the car's computer to send an exact code. The computer will recognize this code and include it into the list of approved key. In some cases, a scanner can also delete lost or stolen keys.
You can also program new keys by using the EEPROM. It is more complex and requires a deep understanding of how electronic systems operate. This is why it's best left to a professional that has years of experience working on these types of systems.
Locksmiths can program keys quickly by using onboard programming. If reprogram car key is done properly it could take just one minute. If the key is not in the correct condition or the procedure isn't followed exactly, the process could take up to half an hour.
There are numerous key programmer scanners available that can be used with different car models and makes. Both the Smart Pro and Autel IM608 Pro have become extremely popular among locksmiths due to their wide range of models for vehicles. However, neither will be able to program every vehicle in existence. In addition, these machines are expensive. It is recommended to purchase one that will receive regular updates from the manufacturer as new technologies are developed. Your programming machine will quickly become outdated if you don't do this.
