Automotive Locksmith Key Programming
Most modern-day cars require some kind of key programming. Depending on the vehicle's make and model, the procedure can be as simple as programming onboard using a spare key that works or as complex as OBD2 or EEPROM programming.
Most US and Asian automakers have a programming protocol that they share with auto tool makers, so they can design hardware or software for locksmiths in the automotive industry.
Transponder Chips
Transponder chips are used in a lot of modern cars to stop theft of cars. These are tiny computer microchips which emit radio waves of low-level. The microchips are equipped with a unique serial number that authenticates your keys when you connect it to the ignition barrel. If your vehicle does not recognize the signal and the engine is shut down. This technology has proven to be an enormous success in preventing auto theft. This technology has also helped car owners save a good amount of money by not having to replace their vehicles.
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 car thieves would use a flat screwdriver to force the ignition switch of your car to go into "on" mode, or wire it hot to get around the system. Transponder chips have dramatically reduced these types of thefts.
When you insert a transponder key into the ignition, it transmits an electrical signal that is received by a hidden antenna circling the barrel of the ignition. The antenna is programmed with the frequency of the chip inside the key. The car's computer onboard will recognize that the key is legitimate and allow fuel to flow, turn up the starter or begin it.
Depending on the manufacturer, certain vehicles can only accept the specific type of transponder chip. It is therefore essential that your locksmith for cars is equipped with the correct equipment to program your keys and remotes for your vehicle.
A reputable locksmith for cars should have an instrument for programming keys for multiple vehicles that works with different car manufacturers and models. This is a cheaper alternative to purchasing individual tools for every brand of vehicle. They are not as common but there are automotive key programmers that can only work on a specific type of vehicle. The best automotive locksmiths have the tools to work on any vehicle. Make sure you select a reputable firm that has this kind of equipment.
Key FOBs
Key FOBs are programmeable transponder chips that allow your vehicle to open doors and start the engine using a push button ignition. They also have buttons you can press to activate features like trunk release, door locks or control of the fuel flap. Some fobs can be controlled with the press of buttons. For instance the "smart key" that allows you summon your car to tight parking spaces, like the Genesis GV60 or a Tesla or Genesis GV60.
While some replacement keys can be programmed with the help of a user manual, you'll often require an auto locksmith to have a new one programmed in case yours stops functioning. A professional is better equipped to connect the computer of your vehicle to the OBD port located under the steering wheel.
The majority of key fobs come with security features to make it more difficult for criminals to replicate and clone the signals that they transmit. Some key fobs have pseudo-random code generators which generate a different unlock code every time you press the button. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.
In some instances, you can buy an alternative keyfob from an auto dealer or other retailer. Your automotive locksmith will then program it to work with your vehicle. This is because the majority of major US and Asian auto manufacturers share their key-fob programming protocols with third-party companies that create the tools used by locksmiths who program their customer's keys.
Some aftermarket key fobs may be advertised as compatible with any vehicle. However, locksmiths for automotive recommend against using them because they are likely to work poorly or even not at all. They recommend buying fobs made specifically for your vehicle to ensure they work correctly and are less susceptible to issues such as interference or incompatibility. This will save you money in the long run by avoiding costly repairs or replacements for your fobs.
Tools for programming vehicles used by manufacturers
Automotive technologies have come a long way, and today's vehicles require computers to function. One of the most important components of this technology is a transponder chipset that must be programmed into 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 will not start if the keys are not correct.
These key fobs can be a little more complex than a traditional mechanical key. This is why they are handled by experienced professional auto locksmiths. The cost of a car key fob varies according to the type and model of key, but it is generally between $85 and $400. This includes the cost of labor to program the key fob as well as the cost of any needed replacement parts.
Car key fobs are more complex because they utilize a software system that works with the computer onboard of the car. The software blocks unauthorized access by only allowing the key to operate if it has been programmed to the car in question. This means that if your keys replaced, you'll need have the new key fob programed to the car to function.
The most common method to do this is by using a car key programming tool that is compatible with the brand 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 tool could be a simple handheld device or a more expensive one that is capable of performing many things beyond key programming (like reading and cloning eeprom files in the ECU).
Some people may attempt to program their keys by themselves using these tools. However this should be left to an expert auto locksmith. It's easy to make mistakes with the software systems if you don't understand the nuances. This can lead to damage. The most important thing to keep in mind is that an experienced professional can assist you in avoiding these problems.
On-Board programming
If your car is older than you, you'll still have a traditional metal key to open the doors and turn over the ignition. Modern cars come with transponders that must be acknowledged and accepted more info by the computer system before it can start. This is an additional layer of protection that can stop car thieves from starting a stolen car and driving away with it. A licensed locksmith has the tools and software to program a new key that will work with your car's security system.
Your locksmith will first need to acquire a key blank that is compatible with your vehicle's make and model. Once the key is in hand the locksmith will connect the programming scanner to the diagnostic port of your car. This will place the car into a special programming mode that 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 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 be able to delete lost or stolen keys from the system.
You can also program new keys with the EEPROM. It is more complicated and requires an in-depth understanding of how electronic systems function. This is why it should be left to a professional who has years of expertise working on these types of systems.
Onboard programming is the fastest method for locksmiths to program the new key. It takes as little as an hour if everything is executed correctly. If the key is not in the right condition or the procedure isn't followed exactly, the process can take as long as a half hour.
There are numerous key programmer scanners which can work with different 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. However, neither can be programmed for every vehicle on the market. In addition, these machines are expensive. It's best to purchase one that will receive regular updates from the manufacturer whenever new technologies are introduced. If not, your computer will become obsolete quickly.
