Automotive Locksmith Key Programming
Modern cars need some form of key programming. Based on the model and manufacturer the process could be as simple as using an extra key to program the onboard computer, or as complicated as OBD2 programming or EEPROM.
Most US and Asian automobile manufacturers share their programming protocols with auto tool manufacturers in order to create tools and hardware for locksmiths in the automotive industry to use.
Transponder Chips
Most newer cars use transponder chips in order to prevent theft. These are tiny computer microchips which emit radio waves of low-level. They have a unique serial number that authenticates the key to your car 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 proven to be an enormous success in preventing auto theft. It has also saved many car owners a lot of money since they don't have to buy new their cars.
The principle of the transponder system is to make it impossible for thieves to start your vehicle without the correct key. In the past, thieves would use the flat screwdriver to push the ignition switch of your car into the "on" mode, or hot-wire it in order to get around the system. Transponder chips have drastically decreased the likelihood of theft.
When you insert a transponder keys into the ignition, it will send the signal which is detected by a hidden antenna circling the barrel of the ignition. The antenna is programmed to detect the specific frequency of the chip within the key. The car's onboard computer will then detect that the key is valid and allow fuel to flow, turn the starter or start it.
Depending on the manufacturer some vehicles will only recognise the specific type of transponder chip. It is therefore essential that your automotive locksmith is equipped with the appropriate equipment to program your keys and remotes for your vehicle.
A good automotive locksmith should have a multi-vehicle key programming tool that can work on many different models and manufacturers of cars. This is a far more cost-effective approach than purchasing separate tools for each type of vehicle. These aren't as popular, but there are specialised automotive key programming tools that can only work on a particular model of vehicle. The top automotive locksmiths have the right equipment to tackle any type of vehicle, so make sure you choose a reputable firm that has these types of tools.
Key FOBs
As the name implies, key FOBs are home to the transponder chips that can be programmed to allow your vehicle to identify and unlock the doors, or start the engine with a push-button ignition. It is also possible to press buttons to activate features like trunk releases, door locks or fuel flap controls. Certain fobs come with additional functions that can be controlled using the button presses, such as the "smart" key fob that lets you bring your car into tight parking spots, like you would with a Tesla or Genesis GV60.
You can program replacement key fobs yourself with the assistance of the user guide, however you will need to call an automotive locksmith in the event that yours has stopped working. This is because a professional locksmith has the right equipment and access to the programming tools required to connect your car's computer via the OBD (OBD) port that is located under the steering wheel.
Today, most key fobs come with security features that make it difficult for attackers to clone or replicate the signals they transmit. Some key fobs have pseudo-random code generators, which generate a new unlock code each time you press the button. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In some instances, you can buy the replacement keyfob at 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 use the same key-fob programming protocol with the third-party companies who make the tools used by locksmiths who program their customer's keys.
Certain key fobs from the aftermarket may be advertised as being compatible with vehicles of all kinds. However, automotive locksmiths advise against using them since they're likely to function poorly or not work at all. They suggest purchasing fobs that are designed specifically for your vehicle to ensure they work correctly and are less susceptible to issues like interference or incompatibility. This will save you money over the long term by avoiding expensive repairs or replacing your fobs.
Toolkits for Programming Vehicles of Manufacturers
Automotive technology has progressed a lot, and today's vehicles require computer technology to function. One key element of this technology is a transponder chip which must be programmed into the vehicle by an expert locksmith or dealer/mechanic in order to work. Key fobs with embedded security features that prevent hot-wiring (like in a film) and the car will not start if you don't have the correct key.
Key fobs are a little more complex than a traditional mechanical key. This is why they are usually placed in the hands of experienced, professional auto locksmiths. The cost of a key fob may vary depending on the car model and the key type however, they generally cost between $85 and $400. This includes labor costs to program the keyfob, as well as any replacement parts.
To complicate the process the car key fobs utilize a specific software system to work with the car's onboard computer. The software prevents unauthorised access by only allowing keys that have been programmed for a specific car to work. If you decide to replace your keys, you'll need to program the new key fob into the car to allow it to work.
The most common way to do this is by using an auto key programming tool that is compatible with the model of the vehicle. This tool allows the locksmith to connect to the OBD port (OBD) in the vehicle and then enter an programming mode. The key programming device could be a handheld device that's affordable or sophisticated and capable of doing more than just program keys (like reading the eeprom file 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. It's easy to make a mistake using the software systems if you don't know the nuances. This could lead to damage. 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 open doors and turn off the ignition. Modern vehicles have transponders that must be recognized and accepted by the computer system to start. This is a further 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 needed to create a key that will work in your car's system.
The locksmith needs to purchase a blank key that is compatible with the model and make of your vehicle. Once your locksmith has the key, he will connect the scanner for programming to the diagnostic port of your vehicle. This will put the vehicle into the mode of programming that allows the locksmith to add a new key into the system.
To accomplish this, the key programmer scanner will communicate with the car's computer system to transmit an exact code. The computer will be able to recognize the code and add it to the list of keys approved by. In some instances, the scanner will also be able to delete keys that are stolen or lost from the system.
Programming EEPROM is another method that can be used to program new car keys. It is more complex and requires a deep understanding of electronic systems. This is why it's best left to a professional who has a lot of expertise working on these types of systems.
Onboard programming is the quickest method for locksmiths to program an entirely new key. It can take as little as a minute when everything is executed correctly. However, if the key isn't in correct state or the procedure isn't followed exactly, it can take as long as a half hour.
There are a variety of key programmer scanners available that work with various vehicle models and makes. Both the Smart Pro and Autel IM608 Pro have become very popular among locksmiths due to their broad range of models for vehicles. However, no system will be able to program every vehicle in existence. Additionally, these devices are expensive. It's a good idea purchase a programer that is updated regularly as the manufacturer develops new technologies. If not, your computer will become obsolete quickly.
