Car Key Reprogramming Is Convenient and Cost-Effective

Traditionally, the most effective way to program new car keys is to go to the dealership. However, you can save some money by finding a local locksmith that offers the reprogramming of car keys.

Check the owner's manual for more details. Here are some general guidelines.

Lost or Stolen Car Keys

A locksmith might be able to reset a blank key so that it will work with your vehicle if you've lost your keys or if they were stolen. This process is similar to how you would program a new remote to work with your TV. This is because the keys of most modern vehicles are equipped with transponder chips that communicate with the computer system within the car to turn it on and off, lock the doors, etc. Depending on the brand and model of your vehicle, the key may also include buttons that allow you to open or close the doors or activate the alarm, and more.

You'll need to determine which blanks and tools are needed for your vehicle. This will help you decide if you can do it yourself or need to hire an expert. Once you have all the necessary equipment, follow the steps included with your key fob or transponder chip to start the process.

Be aware that some models of cars permit dealers only to make an entirely new key. In this instance, you should contact the dealership for assistance. They can program the new key to start your car in the same way as the old one.

Another question people frequently ask is if they can change the programming of an existing key to work with their car. While it is possible to do this in a few instances, the majority of manufacturers will only make the key work with a vehicle that is under their control. This will stop other individuals from being in a position to steal your vehicle through changing the code of a key that is not in use to work.

A professional is the best choice in this situation. They will examine the situation and determine if it's safe to proceed and how to proceed. They will also be able to offer you additional tips on how to better protect your vehicle.

Key Fobs

Key fobs are a convenient way to consolidate multiple functions into a single, portable package. By pressing a button, or a proximity scan, car owners can control door locks, ignitions systems, and more. This eliminates the need for physical keys that are traditional and can cut down on the costs related to replacing lost or stolen keys to cars. Fobs can also be used to create controlled entry for commercial and industrial buildings. By connecting their backends to a central computer facility administrators can program RFID readers and designate access levels for employees, guests or customers.

While most cars are designed with security in mind, there are those who seek to exploit security flaws. With cheap hardware, it's possible for a few criminals to penetrate a vehicle's system and then drive off with the vehicle. Fobs have several built-in protections to mitigate against such attacks. Specifically, they transmit passcodes that are changed every time the fob is activated, and then automatically expire after a predetermined time.

Fobs have also been designed to be secure from wireless hacking. Most modern key fobs use advanced encryption protocols to stop hackers from intercepting codes transmitted. They also employ RFID readers with an unique ID that prevents multiple fobs from gaining access to the same space at the same time.


Consult your owner's guide for specific instructions specific to your vehicle prior to attempting to reprogramme your key fobs. The process of reprogramming is the same for all major models, but they will differ in minor details. In some cases you may need to contact locksmiths to get assistance.

The first step in the reprogramming process is to remove your old fob, and then put it in a secure location. All other key fobs need to be prepared. Once you've done this then get in the driver's seat and shut all doors, with the exception of the driver's side door. This is required to activate your car's reprogramming feature.

With the engine of your car turned off, hold your new fob in the window on the driver's side and press the lock button. You should hear a lock noise within a few minutes. This means that your fob has been successfully changed into a new program. Repeat the process for all of your other fobs.

Transponder Chips

The transponder chip that is located in the top part of a modern smart key, fob, also known as a remote, is what makes your car start when you use it. The chip transmits an identification code to the engine immobilizer of your car and informs it that it's a valid key and not a potentially stolen one. The chip transmits this ID code via radio signal to the computer of the car. If the ID code matches the one in the memory of the vehicle, the car's security system will turn off the immobilizer and allow the engine go. The security light on the dashboard will go out once this has happened.

If your car has a transponder but doesn't seem recognize the new key you've got, you can ask a locksmith to cut and program a replacement.

If you have a spare key, it may already have transponder chips, but you should verify this before paying to duplicate it.

Since 1995, the majority of car makers have improved their systems to prevent thieves from connecting an ignition to a hot wire and driving away with the ignition.
