Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Based on the car's make and model, the procedure can be as simple as programming onboard using a spare key that works or as complicated as OBD2 or EEPROM programming.
The majority of US and Asian car manufacturers use the same programming protocols as auto tool manufacturers in order to create software and hardware for locksmiths in the automotive industry to use.
Transponder Chips
Transponder chips are found in many newer cars to stop theft of cars. These are tiny computer microchips that emit radio waves of low-level. They have a unique serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal it will shut down the engine. This technology has proven to be an enormous success in preventing theft of cars. This technology has also helped car owners save a huge deal of money since they don't have to purchase new cars.
The principle behind the transponder system is to make it difficult for thieves to start your car without a key. In the past, car thieves used a flat screwdriver to force the ignition switch of your car to go into "on" mode or even hot-wire it in order to evade the system. Transponder chips have drastically reduced the number of thefts.
When you insert the transponder keys in the ignition the signal is picked up by an antenna hidden around the barrel. The antenna is programmed to read the specific frequency of the chip within the key. The car's computer onboard will recognise that the key is valid and allow fuel to flow, turn the starter or start it.
Certain vehicles only recognize a certain type of transponder chip depending on the manufacturer. This is why it's crucial to make sure that your automotive locksmith has the right equipment to program your car's keys and fobs properly.
A reputable locksmith for cars should have a multi-vehicle key programming tool 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 aren't as popular however, there are specialist automotive key programmers that are able to only work on a specific brand of vehicle. The best automotive locksmiths are equipped to work on any vehicle. Be sure to choose an established company that has this kind of equipment.
Key FOBs
Key FOBs are programmable transponder chip devices that allow your vehicle to open doors and begin the engine with a push button ignition. You can also press buttons to activate features such as trunk locks, door locks or controls for the fuel flap. Some fobs have additional functions that can be controlled using the button presses, such as a "smart" key fob that lets you bring your car to parking spots that are tight, like you would with the Genesis GV60, Tesla or Genesis GV60.
While some replacement keys can be programmed with the assistance of a user's manual but you'll usually need an automotive locksmith to get a brand new one programmed if the one you have isn't functioning. This is because an expert locksmith has the equipment that is specialized and access to the programming tools required to connect your car's computer to the on-board diagnostics (OBD) port located beneath the steering wheel.
Most key fobs today include security features that make it difficult for criminals to clone or replicate the signals they transmit. Certain key fobs come with pseudo-random code generators that generate a new 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 buy an alternative key fob from the dealer or other retailer and have it programmable by your automotive locksmith to work with your specific vehicle. This is because the majority of major US and Asian automakers use the same key-fob programming protocol with the third-party companies who create the tools used by locksmiths for programming their customers' keys.
Certain aftermarket key fobs can be marketed as being compatible with all vehicles. However, locksmiths for automotive strongly discourage using them as they're likely to function poorly or not work even work at all. Instead, they suggest buying fobs designed specifically for your vehicle, so that you can be sure they'll function properly and be less prone to issues like interfering or not working. This will save you money over the long term by avoiding costly repairs or replacing your fobs.
Vehicle Manufacturers' Programming Tool
Automotive technologies have come a long way and modern vehicles require computers to function. One key element of this technology is a transponder chip which needs to be programmed to the vehicle by an auto locksmith or dealer/mechanic order to work. Key fobs are fitted with security features that prevent hot-wiring, like in a film. The car won't start if the keys are not correct.
Key fobs can be somewhat more complicated than a conventional mechanical key. This is why they are usually handled by experienced, professional auto locksmiths. The cost of a car key fob varies dependent on the model and type of key, but is typically between $85 to $400. This includes the labor cost to program the keyfob as well as any replacement parts.
Car key fobs are more complex due to the fact that they use an operating system that communicates with the onboard computer of the car. The software prevents unauthorized access by allowing the key to operate only if it's programmed to that specific car. If you replace your keys, you'll need to program the new key fob to the car for it to function.
This is accomplished by using a tool for programming car keys that is compatible with your vehicle's brand. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) within the vehicle and then enter an programming mode. The key programming device can be a handheld device that's inexpensive or one that is fancy and can do more than just program keys car key programming (like reading the eeprom files in the ECU).
Although some people might attempt to program their own keys using these tools, this is a job best left to an experienced auto locksmith. If you're not familiar with the aspects 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 a professional with experience can help you avoid these problems.
On-Board Programming
If your car is of a certain age, you'll still have a key from the past that you can use to open the doors and turn off the ignition. Modern cars have a transponder that must be acknowledged and accepted by the computer system to start. This is a further security measure to prevent thieves from stealing the car and driving away with a stolen vehicle. A locksmith certified has the tools and software required to program a key that will be compatible with your car's security system.
The locksmith will require an uncut key that is compatible with the model and make of your vehicle. Once the key is received the locksmith will connect the programming scanner to your car's diagnostic port. This will put the car into a special programing mode, which will allow locksmiths to add the key to the system.
The key programmer scanner communicates with the computer in the vehicle to transmit an electronic code. The computer will recognize the code and add it into the list of keys that are approved. In certain situations the scanner will also erase keys that were stolen or lost.
You can also program new keys with EEPROM. It is more complicated and requires a thorough understanding of electronic systems. It is best to delegate it to a professional with expertise with these systems.
Locksmiths can program keys quickly with onboard programming. It takes as little as one minute if everything is executed correctly. If the key is not in good working order or the procedure isn't followed precisely, the procedure could take as long as a half hour.
There are many key programmer scanners that support different vehicle models and brands. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due their wide range of models for vehicles. No system can program every vehicle. Additionally, these devices cost a lot. It is recommended to purchase one that will receive regular updates from the manufacturer when new technologies are introduced. Your programming machine will quickly become outdated if you don't take this step.
