Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on your vehicle's model and make, the process may be as simple as using an additional key to programme the computer onboard, or as complex as EEPROM or OBD2 programming.
The majority of US and Asian automakers use the same programming protocols as auto tool makers, so they can develop hardware or software for locksmiths in the automotive industry.
Transponder Chips
Most modern cars are equipped with transponder chips in order to prevent theft. These are tiny computer microchips that emit radio waves at a low level. They have a unique digital serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your car isn't able to recognize the signal, it will shut down the engine. This technology has been extremely successful in preventing car theft. This technology has also saved car owners a great amount of money as they do not have to purchase new cars.
The principle behind the transponder system is to make it impossible for thieves to open the doors of your car without a key. In the past, thieves would use the flat screwdriver to push the ignition switch in your car into "on" mode, or wire it hot to evade the system. Transponder chips have drastically reduced the number of thefts.
When you insert a transponder keys into the ignition, it transmits the signal which is detected by a hidden antenna around the barrel of the ignition. The antenna is programmed to match the frequency of the chip in the key. The onboard computer in the car will then recognise the key as valid and allow fuel flow and power the starter to begin the engine.
Some vehicles only recognize a certain type of transponder chips depending on the manufacturer. It is therefore essential that your locksmith for cars is equipped with the right equipment to program your car's keys and remotes.
A good automotive locksmith should have a multi-vehicle key programming device that works with different car manufacturers and models. This is a much cheaper option than buying individual tools for each brand of vehicle. They are not as common, but there are specialised automotive key programmers that can only be used on a specific type of vehicle. The best automotive locksmiths are equipped to work on any vehicle. Make sure you select an established company that has this kind of equipment.
Key FOBs
As the name implies, key FOBs contain transponder chips programmable that enable your car to recognize and unlock the doors or start the engine with a push-button ignition. You can also press buttons to trigger features such as door locks, trunk releases or controls for the fuel flap. Some fobs also have additional functions that can be controlled by the press of a button like the "smart" key fob that allows you to summon your car into tight parking spots similar to a Tesla or Genesis GV60.
While some replacement keys can be programmed by you with the assistance of a user's manual but you'll usually require an automotive locksmith to have a new one programmed if yours stops functioning. A professional is better equipped to connect your computer to the vehicle via the OBD port under the steering wheel.
The majority of key fobs today come with security features that make it difficult for attackers to duplicate or duplicate the signals they transmit. They include pseudo-random sequence generators that generate a new unlock code each time you press the key fob's button. This stops attackers from recording and playing back the unlock signal in order to gain access to your vehicle.
In most cases, you can purchase an alternative key fob from the dealer or other retailer and then have it programmed by your locksmith in your car to work with your particular vehicle. This is because the majority of major US and Asian auto manufacturers use the same key-fob programming protocol with the third-party firms who create the tools used by auto locksmiths to program their customers' keys.
Some aftermarket key fobs may be marketed as being compatible with vehicles of all kinds. However, locksmiths for automotive strongly discourage using them as they're more likely to perform poorly or even not even work at all. Instead, they recommend purchasing fobs specifically designed for your vehicle, so that you can be sure they'll function properly and be less susceptible to issues such as interference or incompatibility. This will save money over time, as you avoid costly repairs or replacements for your fobs.
Tools for programming vehicles used by manufacturers
Automotive technology has advanced considerably and today's vehicles need computer technology to function. Transponder chips are an essential part of this technology. It must be programmed by a locksmith mechanic or dealer to function. Key fobs are fitted with security features to prevent hot-wiring, as in a film. The car will not start if the keys are not correct.
Key fobs are a little more complex than your traditional mechanical keys and that's why you'll usually find them in the hands of a skilled professional auto locksmith. The cost of a car key fob varies according to the model and type of key, but is generally between $85 to $400. This includes the cost of labor to program the keyfob as well as any replacement parts.
These car key fobs are more complicated because they use software that interacts with the onboard computer of the car. The software prevents unauthorized access by only permitting the key to function if it has been programmed to the car in question. This means that if your keys replaced, you'll have to have the new key fob programed to the car in order to function.
This is accomplished by using a programming tool for car keys that is compatible with the brand of your vehicle. This tool allows the locksmith to connect to the OBD port (OBD) within the vehicle and then enter a programming mode. The key programming device could be a handheld device that's affordable or extravagant and can do more than just programming keys (like reading the eeprom file inside the ECU).
Although some people might 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 here mistakes with the software systems if you don't know the nuances. This could lead to damage. The most important thing to remember is that a professional with experience can assist you in avoiding these problems.
On-Board programming
If your car is old enough that it has a key, it might still come with a metal key that can be used to open doors and turn on the ignition. Modern cars are equipped with transponder chips that must be recognized by the computer system of the car to begin. This adds an extra layer of protection that can stop car thieves from starting a stolen car and driving off with the car. A certified locksmith will have the necessary tools and software to create a new key that is compatible with the security system of your vehicle.
Your locksmith will have to acquire a blank key compatible with your vehicle's model and make. Once your locksmith has the key, he will connect the programming scanner to the diagnostic port of your vehicle. This will put your car into an exclusive programming mode which 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 send the code. The computer will recognize this code and add it to the list of approved key. In certain instances the scanner may also be able to erase keys that are stolen or lost from the system.
EEPROM programming is another method that can be used to program new car keys. It is more complicated and requires a deep understanding of electronic systems. This is why it's best left to a professional that has extensive experience 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 done correctly. However, if the key isn't in right situation or the procedure isn't strictly followed, it could take up to an hour.
There are a variety of key programmer scanners available that support different car models and makes. The Smart Pro and the Autel IM608 Pro are both popular amongst locksmiths because they cover a wide range of vehicles. No system can program every vehicle. They are also expensive. It is a good idea to purchase a programer that is updated regularly when the manufacturer introduces new technologies. In the event that your machine is not updated, it will soon become obsolete.
