Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the vehicle's make and model, the process can be as simple as onboard programming with a spare 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 manufacturers, so they can develop hardware or software for automotive locksmiths.
Transponder Chips
Most newer cars use transponder chips to prevent car theft. These are microchips in the form of computers that emit low-level radio signals. They have a unique serial number that authenticates the key to your car 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 an immense success in stopping auto theft. This technology has also helped car owners save a huge amount of money since they don't have to replace their vehicles.
The transponder system's basic idea is to make it hard for thieves to open the doors of your car without the right key. In the past, thieves would force your ignition switch to the "on" position with a flat screwdriver or even use hot wires to disable the system entirely. These kinds of thefts have drastically reduced thanks to the introduction of the transponder chip.
When you insert a transponder keys into the ignition, it will transmit a signal that is received by a hidden antenna that is positioned around the barrel of the ignition. The antenna is programmed to detect the specific frequency of the chip within the key. The computer onboard of the car will then recognize the key as valid and will allow fuel flow, power the starter or start the engine.
Some vehicles only recognize a specific type of transponder chip, depending on the manufacturer. It is therefore important that your locksmith in the automotive industry is equipped with the appropriate equipment to program your car's keys and remotes.
A good automotive locksmith should have a multi-vehicle key programming device that can work on many different models and manufacturers of cars. This is a cheaper alternative than buying separate tools for each type of vehicle. They are not as common, but there are specialised automotive key programmers that are able to only be used on a specific brand of vehicle. The top automotive locksmiths have the appropriate equipment to tackle any type of vehicle, so make sure you find a reputable company that has these types of tools.
Key FOBs
Key FOBs are programmable transponder chip devices that permit your vehicle to unlock doors and start the engine with the push of a button ignition. You can also use the buttons to activate features such as trunk releases, door locks or controls for the fuel flap. Certain fobs can be controlled by pressing buttons. For instance an "smart key" that allows you summon your car to tight parking spaces, like a Tesla or Genesis GV60.
While some replacement keys can be programmed by you using the assistance of a user's manual, you'll often require an automotive locksmith to get a brand new one programmed if the one you have isn't working. This is because a professional has the equipment that is specialized and access to the programming tools required to connect your car's computer through the on-board diagnostics (OBD) port located beneath the steering wheel.
The majority of key fobs come with security features to make it more difficult for criminals to replicate and clone the signals that they transmit. Some key fobs have pseudo-random code generators, which generate a new unlock code every time you press the button. This is to prevent attackers from capturing and playing back the unlock signal to gain access to your vehicle.
In certain instances you can purchase an alternative keyfob from an auto dealer or other retailer. Your locksmith at your auto will then program it to work with your vehicle. This is because the majority of major US and Asian automakers have key-fob programming protocols with the third-party firms who make the tools used by auto locksmiths to program their customer's keys.
Certain key fobs from the aftermarket may be advertised as compatible with any vehicle. However, locksmiths for automotive recommend against using them because they are likely to work poorly or not at all. Instead, they recommend purchasing fobs that are specifically made for your vehicle, so that you can be certain they'll function properly and be less susceptible to issues such as interfering or incompatibility. This will save money over time, as you avoid costly repairs or replacements for your fobs.
Vehicle Manufacturers' Programming Tool
The automotive industry has come a long way, and today's vehicles require computers to function. Transponder chips are an essential component of this technology. It must be programmed by a locksmith, mechanic or dealer to work. Key fobs come with built-in security features that will prevent hot-wiring (like in a film) and the car won't start if it doesn't have the correct key.
These 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 the car key fob can vary according to the more info model and type of key, but is usually between $85 and $400. This includes the labor to program the key fob, as well as the costs for any required replacement parts.
The car key fobs are more complicated because they utilize a software system that works with the onboard computer of the car. The software blocks access to unauthorised users by only allowing keys programmed for a specific vehicle to work. This means that if you get your keys replaced, you'll need to have the new key fob programmed to the car to function.
This is accomplished by using a programming tool for keys for cars that are compatible with the brand of your vehicle. This tool lets the locksmith connect to the onboard diagnostics port (OBD) within the vehicle and then enter the programming mode. The key programming tool could be a simple handheld device or a more expensive one that can perform a wide range of things beyond just key programming (like reading and cloning EEEPROM files in the ECU).
Although some people might attempt to program their own keys using these tools, it's something best left to a professional auto locksmith. Unless you're familiar with all the ins and outs of the various software systems, it's possible to accidentally change settings that could damage the vehicle. It's important to remember that a professional with experience will help you avoid these issues.
On-Board programming
If your car is older than, it may still come with a metal key that you can use to open doors and turn the ignition. However, modern cars have transponder chips that must be recognized by the computer system of the car in order to start. This adds another layer of security to keep thieves from stealing the car and then driving off with a stolen car. A locksmith who is certified has the tools and software needed to program a key that can work in your car's system.
Your locksmith will first need to purchase a blank key that is compatible with your car's make and model. Once your locksmith has the key, he'll connect the programming scanner to the diagnostic port of your vehicle. This will put your car into an exclusive programming mode that allows the locksmith to add a new key to the system.
To accomplish this, the key programmer scanner will communicate with the car's computer and send a specific code. The computer will detect this code and include it into the list of keys that are authorized. In certain instances the scanner will be able to delete keys that are stolen or lost from the system.
The EEPROM programming method is a different one 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 that has years of experience working with these kinds of systems.
Locksmiths can program a key quickly by using onboard programming. If everything is done properly, it can take just one minute. If the key isn't placed in the correct situation or the procedure is not strictly followed, it could take as long as a half hour.
There are many different key programmer scanners which can work with different makes and models of vehicles. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due their wide range of vehicle models. However, neither can program every single vehicle that exists. Furthermore, these systems are quite expensive. It's a good idea buy a programmer that receives regular updates when the manufacturer introduces new technologies. Your programming machine will quickly become obsolete if you don't take this step.
