Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Depending on your vehicle's model and manufacturer the process could be as simple as using an extra key to program the onboard computer, or as complicated as EEPROM or OBD2 programming.
Most US and Asian automakers have a programming protocol that they share with auto tool makers, which means they can design tools or hardware for automotive locksmiths.
Transponder Chips
Transponder chips are used in a variety of newer vehicles to guard against theft of vehicles. 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 car doesn't recognise the signal it will shut down the engine. This technology has been a huge success in preventing car theft. It has also saved many car owners a lot of money because they don't have to buy new their vehicles.
The principle of the transponder system is to make it difficult for thieves to open the doors of your vehicle without a valid 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 dramatically reduced these types of thefts.
When you place the transponder key in the ignition the signal is received by an antenna hidden around the barrel. The antenna is programmed to detect the particular 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, power up the starter or begin it.
Some vehicles only recognize a specific type of transponder chip according to the manufacturer. This is why it's important to ensure that your automotive locksmith has the right equipment to program your vehicle's keys and fobs correctly.
A reputable locksmith for cars should have an instrument for programming keys for multiple vehicles that is compatible with different models and car brands. This is a less expensive option than purchasing separate tools for each brand of vehicle. These aren't as popular however, there are specialist automotive key programmers that can only be used on a specific model of vehicle. The most reliable automotive locksmiths will have the right equipment to tackle any type of vehicle, so make sure you choose a reputable business with these kinds of tools.
Key FOBs
As the name suggests, key FOBs are home to the programmable transponder chips that enable your vehicle to recognize and open the doors or start the engine using a push button ignition. They also have buttons that you can press to activate features such as trunk release, door locks or fuel flap control. Certain fobs come with additional functions that can be controlled using the press of a button for example, a "smart" key fob that lets you summon your car into parking spaces that are difficult to access similar to a Tesla or Genesis GV60.
While certain replacement key fobs can be programmed by you 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 working. A professional locksmith is more equipped to connect your computer to the car via the OBD port on the steering wheel.
The majority of key fobs are equipped with security features to make it difficult for attackers to duplicate and copy the signals they transmit. Certain key fobs come with pseudo-random code generators, which generate a unique unlock code every time you press the button. This prevents attackers capturing and playing back the unlock signal in order to gain access to your vehicle.
In many cases you can buy an alternative key fob from the dealer or from another retailer and have it programmed by your automotive locksmith to fit your particular vehicle. This is due to the fact that most of the major US and Asian car makers have key fob programming protocols with third-party firms that create the tools auto locksmiths employ to programme keys for their customers.
While some aftermarket key fobs are marketed as being compatible with all vehicles However, the majority of locksmiths in the automotive industry don't recommend using them since they are likely to function poorly or not at all. They suggest purchasing fobs that are designed specifically for your vehicle to ensure they will work properly and are less susceptible to issues like interference or incompatibility. This will save you money over the long term by avoiding costly repairs or replacing your fobs.
Tools for programming vehicles used by manufacturers
Automotive technology has progressed a lot, and today's vehicles require computers to function. One of the key components of this technology is a transponder chip which needs to be programmed to the vehicle by a locksmith or dealer/mechanic in order to function. These key fobs have built-in security features that will prevent hot-wiring (like in a movie) and the car won't start without the correct key.
These key fobs are a bit more complex than your traditional mechanical key and are the reason you'll typically find them in the hands of a skilled, professional auto locksmith. The cost of the car key fob is according to the model and type of key, but is typically between $85 to $400. This includes the labor to program the key fob and the cost of any needed replacement parts.
To complicate the process the car key fobs make use of a special software to work with the car's onboard computer. The software prevents unauthorised access by only allowing keys that have been programmed for a specific vehicle to function. If you change your keys, you will have to program the new key fob to the car to allow it to work.
This is done by using a programming tool for car keys that is compatible with the brand of your vehicle. This tool allows a locksmith to connect to the OBD port of the vehicle and then enter programming mode. The key programming tool can be a handheld device that is inexpensive device or a more expensive one that can perform many things beyond key programming (like reading and cloning Eeprom files within the ECU).
Some people may attempt to program their keys on their own using these tools. However this should be left to an experienced auto locksmith. If you're not familiar with the aspects of the various software systems, it's easy to accidentally change settings that could potentially damage the vehicle. It's important to keep in mind that an experienced professional will help you avoid these problems.
On-Board programming
If your vehicle is old enough that you'll have a key from the past to open the doors and turn over the ignition. However, modern cars are equipped with transponder chips that need to be recognized by the computer system of the car to begin. This is an additional layer of security that prevents car thieves from starting a car stolen and driving off with it. A licensed locksmith has the tools and software to create a new key that will work with the security system of your vehicle.
First, your locksmith needs to purchase a blank key that is compatible with the make and model of your car. Once the key is in your possession the locksmith will connect the programming scanner to your car's diagnostic port. This will put the vehicle into the mode of programming which will allow the locksmith to add a new key to the system.
The key scanner is programmed to communicate with the computer in the vehicle to transmit a code. The computer will detect this code and include it to the list of keys that are approved. In certain situations, a scanner can also erase keys that were stolen or lost.
You can also program new keys reprogram car key by using EEPROM. It is more complex and requires a thorough understanding of electronic systems. It's best to leave it to a professional who has experience with these systems.
Locksmiths can program keys quickly with onboard programming. It can take as little as an hour if everything is completed correctly. However, if the key isn't in the correct condition or the procedure is not strictly followed, it could take up to a half hour.
There are a variety of key programmer scanners available that can be used with different vehicle models and brands. The Smart Pro and the Autel IM608 Pro are both very well-liked by locksmiths due to the fact that they support a broad range of vehicle models. However, no system can program every vehicle on the market. These machines are also quite expensive. It's best to purchase an instrument that receives regular updates from the manufacturer whenever new technologies are introduced. If not, your computer will become obsolete quickly.
