10 Quick Tips About Automotive Locksmith Key Programming
Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the car's maker and model, the process can be as simple as programming onboard using an extra working key or as complicated as EEPROM or OBD2 programming.
Most US and Asian auto manufacturers use the same programming protocols as auto tool manufacturers, so they can develop software or hardware for automotive locksmiths.
Transponder Chips
Most modern cars are equipped with what are called transponder chips to prevent car theft. These are tiny computer microchips which emit low-level radio waves. The microchips have a unique serial number that authenticates your keys when you insert it into the ignition barrel. If your vehicle isn't able to recognize the signal it will shut down. This technology has proven to be an enormous success in preventing car theft. This technology has also helped car owners save a huge deal of money by not having to replace their vehicles.
The principle of the transponder system is to make it hard for thieves to get into your vehicle without the correct key. In the past car thieves used an ordinary screwdriver to force the ignition switch of your car to go into "on" mode, or hot-wire it to evade the system. Transponder chips have drastically decreased the likelihood of theft.
When you insert the transponder keys into the ignition the signal is picked up by an antenna hidden around the barrel. The antenna is programmed with the frequency of the chip inside the key. The car's onboard computer will then detect that the key is legitimate and allow fuel to flow, turn up the starter or start it.
Certain vehicles only recognize a specific type of transponder chip according to the manufacturer. This is why it's important to ensure that your locksmith for automotive has the right equipment to program your car's keys and fobs properly.
A good automotive locksmith will possess a multi-vehicle programing device which can be used with different automobile models and manufacturers. This is a cheaper solution than buying separate tools for each brand of vehicle. These aren't as popular, but there are specialised automotive key programmers that can only work on a specific brand of vehicle. The best automotive locksmiths are equipped to work on any vehicle. Make sure you select a reliable company that is equipped with this type of equipment.
Key FOBs
The key FOBs are programmable transponder chip devices that allow your vehicle to unlock doors and start the engine with the push of a button. You can also use the buttons to activate features like door locks, trunk releases or controls for the fuel flap. Some fobs can be controlled by pressing buttons. For example, a "smart key" that allows you summon your car to tight parking spaces, like a Tesla or Genesis GV60.
You can program some replacement key fobs yourself with the help of a user guide, but you'll need to contact an automotive locksmith if the one you have has stopped working. A professional locksmith is more equipped to connect your computer to the car via the OBD port under the steering wheel.
The majority of key fobs today have security features that make it difficult for hackers to clone or replicate the signals they transmit. Some key fobs have pseudo-random code generators that generate a different 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 a replacement keyfob from a dealership or another retailer. Your automotive locksmith will then program it to work with your car. This is because most of the major US and Asian car makers share their key fob programming protocols with third-party companies that create the tools locksmiths use to program keys for their customers.
While mobile key programming of the aftermarket key fobs are advertised as compatible with all vehicles however, the majority of locksmiths for automotive don't recommend using them because they're likely to work poorly or not at all. They suggest buying fobs designed specifically for your vehicle to ensure they function properly and are less susceptible to issues like interference or incompatibility. This will save you money over time, as you avoid costly repairs or replacements of your fobs.
Vehicle Manufacturers' Programming Tools
Automotive technology has progressed a lot, and today's vehicles require computer technology in order to function. A transponder chip is an essential part of this technology. It needs to be programmed by a locksmith, mechanic, or dealer to work. Key fobs are fitted with security features to stop hot-wiring, like in a movie. The car won't start without the correct keys.
Key fobs are a bit more complex than the traditional mechanical key and are the reason they are usually 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 usually between $85 to $400. This includes the labor to program the key fob and the cost of any needed replacement parts.
To make the process more difficult the car key fobs use a special software system to communicate with the car's onboard computer. The software blocks access to unauthorised users by only allowing keys programmed specifically for a particular car to work. If you replace your keys, you'll need to program the new key fob to the car to allow it to work.
This is done by using a programing tool for keys for cars that are compatible with the brand of your vehicle. This tool allows locksmiths to connect to the OBD port in the vehicle and then enter the programming mode. The key programming tool can be a handheld device that is inexpensive device or a high-end one that can perform a wide range of things that go beyond key programming (like reading and cloning eeprom files in the ECU).
Some people may try to program their keys by themselves using these tools. However, this is best left to an expert auto locksmith. If you're not aware of all the ins and outs of the various software systems, it's very easy to make a mistake and alter settings that could cause damage to the vehicle. The most important thing to remember is that an experienced professional 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 key made of metal that you can use to open doors and turn off the ignition. Modern cars have transponders that need to be recognized and accepted by the computer system in order to start. This adds another layer of security to keep thieves from starting and then driving off with a stolen vehicle. A locksmith who is certified will have the tools and software needed to program a key that can function in your car's system.
Your locksmith will have to acquire a blank key that is compatible with the 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 the car into a special programing mode, which will allow the locksmiths to add a key to the system.
The key scanner is programmed to communicate with the computer of the vehicle to send a code. The computer will recognize the code and add it to the list of keys that are approved. In some instances, a scanner can also erase keys that were stolen or lost.
You can also program new keys with EEPROM. It is more complex and requires a thorough understanding of how electronic systems function. It's best to leave it to a professional with experience with these systems.
Onboard programming is the most efficient method for locksmiths to program the new key. When everything is done correctly it could take as little as one minute. If the key isn't in good working order or the procedure isn't being followed exactly, the process can 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 to their wide selection of models for vehicles. There is no system that can program every vehicle. These machines are also quite expensive. It is best to buy a programmer which will receive regular updates from the manufacturer when new technologies are developed. Your computer's programming software will soon become outdated if you don't do this.
