The method for doing this by yourself varies from manufacturer to manufacturer. In general, you will need to insert the spare key in the ignition and manipulate it (according to the directions in the owner's manual) until the car enters programming mode. This only lasts for a few moments before the car exits the programming mode.
You'll need repeat this procedure for each key you would like to program once your vehicle is in the programming mode. The instructions contained in your owner's manual should be specific to the type of key and model that you're trying to program, since some models come with additional security features that need to be activated (for instance, a passcode that is required to enter certain programming modes).

Key Programmers
You may be wondering if it's possible to reprogram your key if you have lost them or are replacing them. It depends on the manufacturer, however most cars require that you work with a dealer or auto locksmith to get the new key programmed into the vehicle's system. This requires reprogramming the new key's transponder to match the settings of the car that was originally programmed.
While some vehicles permit this yourself, most require a dealer or professional to use a special tool that is able to connect with the vehicle and read programming data from the ECU. The key is then reprogrammed so that it is compatible with the car's specifications and you can use it as a regular key.
There are a variety of car key programmers, some of which work with specific makes and models of vehicles, while others are more universal and can be used on a wide variety of vehicles. Most of these tools have a tiny screen and a few buttons you press to enter the programming mode. Then, you can plug the device into the OBD-II port to begin reading and programming the new key.
It only takes a few minutes for professionals to program a new key in most vehicles, though certain cars may take longer and require complex procedures to reprogram keys correctly. For instance, some modern vehicles require a particular code that only the car dealer has access to and uses to access the immobilizer's system. In these instances you should delegate the job to professionals to avoid damaging the system and resulting in a non-existent way to start the car.

Key Fobs
Modern key fobs offer a number of convenience and security benefits. They can replace or enhance traditional car keys and control more than just locking doors; they can start the engine, trigger the alarm and perform other functions.
The key fob communicates with the receiver in the vehicle via radio signals. When you press the button on the keyfob, it sends the code to the receiver which then does the job you want it to. Commercial building owners also make use of key fobs to connect them to a larger system of access control. This lets them keep track of who enters and exits and can stop fobs that were lost or here stolen.
Key fobs, as with any electronic device, can malfunction. They can break or lose their signal if they are jostled in pockets and purses. Although they're built to withstand some punishment, they're not indestructible; after all, they're little more than plastic and metal.
If your key fobs stop working, it may be time to change the battery. Be sure to use the correct battery and refer to your owner's manual to learn how to replace it properly. Be sure to follow all other steps required to reprogramme and calibrate the battery.
Wear and tear is a common cause of failing fobs. They can crack or break when they are dropped, bumped against things, and jostled around in pockets and purses. A simple and affordable fix can often be all you need to make your key fobs work again.

They are ideally sized to fit on a PCB and can be printed with high-quality images or extra cutouts made efficiently and neatly using CNC machining. They're also designed to accommodate coin-cell batteries, which are often used in keyfobs. If you need a custom-made key fob case, contact us for an estimate.
Keyless Entry
Keyless entry lets you unlock your car and begin it without needing to insert a physical keys. It utilizes a wireless signal to connect with the car's internal system and it can also allow you to control different features within the vehicle including climate controls or music systems.
Modern keyless entry systems employ rolling code technology to protect against security breaches. It's important to remember that even this technology is not perfect. A thief could use the technique known as "replay attack" to transmit a message that is recorded by the receiver of the car. Once the message has been recorded, a rogue gadget can retransmit this transmission to the vehicle's receiver and gain access.
Depending on your vehicle's make and model, it may be possible to program new keys on your own, or you may need to have an auto locksmith assist you. Certain car manufacturers have an onboard program specifically designed for them and others require you have an advanced programmer attached to the OBD2 connector.
The most popular method of programming new keys for cars is to put the fob of the key in the ignition and then turn it on in a specific sequence. This puts the car into the "programming mode," and once it is activated, one or more fob buttons are depressed to send the digital identity code to the car's computer. The computer saves the code and then removes the car from the programming mode.
Some manufacturers require you to have an advanced computer to program key fobs, and some of these are expensive and difficult to use by a typical person. It's best to leave the work to an automotive locksmith or dealer.
To begin the process of programming a new keyless entry vehicle key, enter your vehicle on the driver's side and shut all the doors EXCEPT for the driver's door. This will stop the system from locking your doors while you attempt to program the key. After that, with the ignition key in place along with the other keys you want to program in the vicinity, push and hold the button on the fob that you want to activate until the danger lights flash twice.
