How to program a Key

Most cars had basic key systems until the turn of the 21st century. Keys were made from metal and had grooves to correspond with the internal parts of the ignition cylinder. As time passed and technology improved and improved, automobile manufacturers began to combine electronic and physical protocols to stop theft. These key systems are referred to as transponder keys or chip keys, and they're designed to make it more difficult for thieves to start the vehicle.


The key chips in the keys have a unique serial number, which transmits a signal to the receiver inside of your car. When the signal is received, it compares it to a code stored in the car's computer. If the codes match, then your car will begin to start. If the codes don't match, your vehicle won't start at all. This is one of the main reasons to keep a spare key for your car, especially if you have transponder-based systems.

The newest models also allow remote management and configuration as well as are cloud-based.

Modern automobiles are equipped with keyless entry systems. The system works by emitting radio signals that are detected by a special keyfob. These signals are then compared against the correct code stored in the car's computer, and if everything is in order, the car will unlock. The car will not start if the signals are not identical. If your key fob is not already programmed, you may follow a few steps to program it.

First, you'll need to make sure that all doors except the driver's door are locked. You'll need the original key fob as well as any extras that you want to program.

Transponder Keys

The chip absorbs the energy and then transmits a radio frequency signal that includes an identification code. The code is matched to the unique serial numbers that are stored in the computer of the car. This helps prevent unauthorized attempts to start the car as only the correct key can do so.

It is believed that this technology will be more secure than traditional car keys because it makes it more difficult for thieves to "hot wire" an automobile and start it. It's not foolproof, and thieves have discovered ways to evade detection and defeat the system. So even cars equipped with transponder keys aren't safe from theft.

To ensure that this method works you'll need at least two key fobs functioning for your vehicle. It's important to have two spare keys in your possession.

The key fobs have electronic chips which communicate with the car's radio via radio signals. The computer compares the code of the key with the database. If the codes match the car starts. If the codes don't match, the car will not start or remain dead. The majority of these electronic keys can be programmed and replaced by an experienced locksmith or auto dealer with the proper equipment.

The process should be relatively easy if you locate a key programmer that is cheap on the internet or in an auto parts store. You will need to follow a set of instructions that includes inserting the ignition key and turning it on, without starting the vehicle, and then switching off the key. You'll have to repeat this procedure a specific number of times within a certain time period for your vehicle to enter programming mode. The door locks will turn on and off or a chime will sound.
