Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on the car's maker and model, the process can be as simple as onboard programming with an extra working key or as complicated as EEPROM or OBD2 programming.
Most US and Asian automakers have a programming protocol that they share with auto tool makers, so they can develop hardware or software for automotive locksmiths.
Transponder Chips
Transponder chips are in many newer cars to prevent car theft. These are microchips in the form of computers which emit radio signals of low-level. They have a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle isn't able to recognize the signal it will shut down. This technology has proved to be an enormous success in preventing auto theft. It has also saved many car owners a significant amount of money since they don't have to replace their vehicles.
The transponder system's basic idea is to make it difficult for thieves to get into your car without the right key. In the past, car thieves would force your ignition switch to the "on" position using a flat screwdriver or even use hot wires to disable the system completely. Transponder chips have dramatically decreased the likelihood of theft.
When you insert a transponder key into the ignition, it will transmit an electrical signal that is detected by a hidden antenna around the barrel of the ignition. The antenna is programmed to read the specific frequency of the chip inside the key. The car's onboard computer will then recognise that the key is genuine and allow the fuel to flow, then power the starter or begin it.
Depending on the manufacturer, some vehicles will only recognise the specific type of transponder chip. This is why it is essential to ensure that your locksmith for automotive has the right equipment to program your car's keys and fobs correctly.
A reputable locksmith for automotive needs to have a multi-vehicle key programming device that can work on many different models and car brands. This is a cheaper option than purchasing individual tools for every brand of vehicle. These are less common but there are automotive key programmers that are able to only work on a particular type of vehicle. The top automotive locksmiths have the tools needed to work on any vehicle. Make sure you select a reputable firm that has this type of equipment.
Key FOBs
The name implies that key FOBs are home to the transponder chips that can be programmed to allow your vehicle to recognize and open the doors, or start the engine with a push-button ignition. They also have buttons that you can push to activate features such as trunk release, door locks or control of the fuel flap. Some fobs can be controlled using buttons. For instance the "smart key" that allows you summon your car into tight parking spaces, like a Tesla or Genesis GV60.
You can program some replacement key fobs yourself with the help from a user guide, but you'll need to call an automotive locksmith in the event that yours has stopped functioning. A professional locksmith is better equipped to connect your computer to the vehicle via the OBD port under the steering wheel.
The majority of key fobs come with security features to make it more difficult for criminals to clone and replicate the signals they transmit. Certain key fobs feature pseudo-random code generators, which generate a new unlock code each time you press the button. This prevents attackers capturing and playing back the unlock signal in order to gain access to your vehicle.
In certain instances, you can buy a replacement keyfob from an auto dealer or other retailer. The locksmith you choose to use will then program it to work with your vehicle. This is because most of the major US and Asian car manufacturers have key fob programming protocols with third-party companies who make the tools that locksmiths utilize to program keys for their customers.
Some aftermarket key fobs may be advertised as being compatible with all vehicles. However, locksmiths for automotive strongly discourage using them as they're more likely to perform poorly or not at all. They recommend buying fobs made specifically for your vehicle so that they will work properly and are less susceptible to issues like interference or incompatibility. This will save you money in the end by avoiding costly repairs or replacing your fobs.
Vehicle Manufacturers' Programming Tools
Automotive technologies have come a long way 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 with embedded security features that prevent hot-wiring (like in a film) and the car won't start if it doesn't have the right key.
These key fobs are a little more complicated than a traditional mechanical key and are the reason you'll usually find them in the hands of a skilled professional auto locksmith. The cost of a key fob will vary based on the vehicle model and the key type, but they typically run between $85 and $400. This includes the labor cost to program the keyfob and any replacement parts.
The car key fobs are more complicated because they use an operating system that communicates with the onboard computer of the car. The software blocks access to unauthorized users by allowing the key to operate only if it's programmed to the car in question. If you replace your keys, you'll have to program the new key fob in the car in order for it to work.
This is accomplished by using a programming tool for car keys that is compatible with your vehicle's brand. This tool permits a locksmith to connect to the OBD port in the vehicle and then enter programming mode. Key programming tools can either be an inexpensive handheld device or a fancy one that is capable of performing various things beyond key programming (like reading and cloning the EEEPROM files in the ECU).
While some people may attempt to program their own keys with these tools, this is an activity best left to a professional auto locksmith. If you're not familiar with the details of the various software systems, it's very easy to accidentally alter settings that could damage the vehicle. It's important to keep in mind that an experienced professional will assist you in avoiding these issues.
On-Board Programming
If your car isn't as old, it may still come with a metal key that you can use to unlock doors and turn on the ignition. Modern cars have a transponder that must be acknowledged and accepted by the computer system to start. This adds another layer of security that prevents car thieves from starting and then driving off with a stolen vehicle. A locksmith certified has the tools and software required to create a key that will be compatible with your car's security system.
Your locksmith will need to acquire a key blank that is that is compatible with your car's model and make. Once the key is received the locksmith will connect the programming scanner to your car's diagnostic port. This will put your vehicle into a specific programming mode, which allows the locksmiths to add the key to the system.
To do this, the key programmer scanner will communicate with the car's computer and send a specific code. The computer will recognize the code and add it to the list of keys that are reprogram car key approved. In some instances the scanner will be able to delete keys that are stolen or lost from the system.
You can also program new keys with EEPROM. It is more complicated and requires an in-depth understanding of how electronic systems work. It's best to leave it to a professional who has expertise with these systems.
Locksmiths can program keys quickly by using onboard programming. If everything is done correctly, it can take just one minute. If the key isn't in the right condition or the procedure isn't followed exactly, the process can take as long as a half hour.
There are many key programmer scanners on the market that support different vehicle models and makes. The Smart Pro and the Autel IM608 Pro are both extremely popular amongst locksmiths because they support a broad range of vehicles. No system can program every vehicle. These devices are also expensive. It is a good idea to purchase a computer that receives regular updates as the manufacturer releases new technologies. Your machine for programming will quickly become obsolete if you do not take this step.
