20 Myths About Automotive Locksmith Key Programming: Busted
Automotive Locksmith Key Programming

Most modern-day cars require some type of key programming. Depending on the vehicle's make and model, the process can be as simple as onboard programming using a spare working key or as complex as EEPROM or OBD2 programming.

The majority of US and Asian car makers share their programming protocols with auto tool makers to allow them to develop tools and hardware for automotive locksmiths to use.

Transponder Chips

Transponder chips are found in a variety of newer vehicles to stop theft of cars. These are microchips in the form of computers that emit radio signals at a 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 isn't able to recognize the signal it will shut down the engine. This technology has been extremely successful in preventing car theft. It also saves many car owners a significant amount of money because they don't have to replace their vehicles.

The basic idea behind the transponder system is to make it impossible for thieves to start your car without the proper key. In the past, thieves would use the flat screwdriver to push the ignition switch in your car to go into "on" mode, or hot-wire it to bypass the system. Transponder chips have drastically decreased the likelihood of theft.

When you place the transponder key in the ignition, the signal is received by an antenna that is concealed around the barrel. The antenna is programmed to match the frequency of the chip in the key. The car's computer onboard will detect that the key is valid and allow fuel to flow, turn up the starter, or even start it.

Certain vehicles only recognize a certain type of transponder chip according to the manufacturer. This is why it's crucial to make sure that your automotive locksmith has the appropriate 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 manufacturers of cars. This is a less expensive alternative to purchasing specific tools for each type of vehicle. These are less common but there are automotive key programmers that are able to only be used on a specific model of vehicle. The best automotive locksmiths will have the proper tools to work on any type of vehicle, so ensure you find a reputable company with these kinds of tools.

Key FOBs


Key FOBs are programmeable transponder chip devices that permit your vehicle to open doors and start the engine with the push of a button ignition. They also have buttons you can push to activate features like trunk release, door locks or control of the fuel flap. Some fobs can be controlled by pressing buttons. For example an "smart key" which allows you to summon your car to parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.

You can program some replacement key fobs yourself using the help of the user guide, however you'll need to contact an automotive locksmith if yours has stopped functioning. This is because a professional has the right equipment and access to the programming tools needed to connect your car's computer via the on-board diagnostics (OBD) port that is located under the steering wheel.

Most key fobs today have security features that make it difficult for hackers to duplicate or copy the signals they transmit. They include pseudo-random generators that generate an entirely new unlock code every time you press the key fob's button. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.

In certain instances you can purchase the replacement keyfob at a dealership or another retailer. Your locksmith at your auto will then program it to work with your car. This is because the majority of major US and Asian automakers share their key-fob programming protocols with third-party companies that produce the tools used by locksmiths who program their customer's keys.

Certain key fobs from the aftermarket may be advertised as being compatible with vehicles of all kinds. However, locksmiths for automotive recommend against using them because they are likely to work poorly or not at all. They recommend buying fobs made specifically for your vehicle so that they work correctly and are less susceptible to issues like interference or incompatibility. This will save money over time by avoiding costly repairs or replacements for your fobs.

The automotive industry has advanced considerably 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 expert locksmith or dealer/mechanic in order to function. Key fobs are fitted with security features to prevent hot-wiring like in a movie. The car will not start without the correct keys.

car key programer can be slightly more complicated than a traditional mechanical key. This is why they are usually in the hands of seasoned professional auto locksmiths. The cost of the car key fob can vary according to the model and type of key, but it is usually between $85 and $400. This includes the labor to program the key fob as well as the cost of any needed replacement parts.

To complicate the process to make the process more complicated, these key fobs for cars utilize a specific software system to communicate with the car's onboard computer. The software prevents unauthorized access by permitting the key to function if it has been programmed to the car in question. If you decide to replace your keys, you'll have to program the new key fob to the car in order for it to work.

The most popular method to do this is by using a car key programming tool that is compatible with the brand of the vehicle. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) in the vehicle and then enter the programming mode. Key programming devices can be a handheld device that's affordable or sophisticated and capable of doing more than just program keys (like reading the eeprom file in the ECU).

Some people may attempt to program their keys on their own using these tools. However it's best to leave this task to an experienced auto locksmith. If you're not familiar with the details of the various software systems, it's possible to accidentally alter settings that could potentially damage the vehicle.

On-Board Programming

If your car isn't as old that it has a key, it might still come with a metal key that you can use to open doors and turn on the ignition.

This adds another layer of security that prevents car thieves from starting and driving away with a stolen car. A locksmith certified has the tools and software necessary to create a key that will work in your car's system.

The key scanner is programmed to communicate with the computer in the car to send the code. The computer will be able to recognize the code and add it to the list of keys approved by. In some instances, a scanner can also delete lost or stolen keys.

Programming EEPROM is another method that can be used to program new car keys. It is more complex and requires an in-depth understanding of how electronic systems work. This is why it's best left to a professional that has extensive experience working on these types of systems.

Locksmiths can program a key quickly using onboard programming. It can take less than an hour if everything is done correctly. If the key isn't in the correct condition or the procedure isn't being followed exactly, the process could take as long as a half hour.

There are a variety of key programmer scanners which can work with different makes and models of vehicles. The Smart Pro and the Autel IM608 Pro are both extremely popular amongst locksmiths because they cover a wide range of automobile models. However, no system will be able to program every single vehicle that exists. Furthermore, these systems are expensive. It's a good idea to purchase a programer that receives regular updates as the manufacturer develops new technologies.
