How do you program a key

Up until the turn of the 21st century the majority of cars had basic key systems. Keys themselves were metal with grooves that matched the internal components of the ignition cylinder. As time passed and technology improved, more and more automobile manufacturers began blending electronic and physical protocols to prevent theft. These key systems are referred to as transponder keys or chip keys, and they're designed to make it difficult for thieves to get into the vehicle.

The automotive key programmer chips in the keys have a specific serial number that sends a signal to the receiver inside your car. When the signal is received it is compared to the code that is 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 in your vehicle, particularly when you use a transponder-based system.

You'll require specialized equipment to be able to program keys. You'll need a blank key that matches the model and make of your car. They can be purchased from the dealership or through locksmiths however, you must be sure that they are the right ones. If you try to use a key that is from an alternative model, it will not work.

After the time has passed you can take out your key and verify that the security indicator on your dashboard has gone out. If it didn't go out, you will need to repeat the procedure for the third time.

The signals are compared to the code that is stored in the computer of the car and, if all is in order the car will be able to unlock. If the signals don't match, the car will not start. If your key fob is not already programmed, you can follow a series of steps to program it.

Transponder Keys

Transponder keys, also referred to as chip keys, have an embedded microchip in the head of the key. When the key is inserted into the ignition lock barrel and turned to ON the antenna ring transmits an energy burst through the transponder chip. The energy is absorbed by the chip and sends back an audio frequency signal that contains an identification code that corresponds up to the unique digital serial number in the car's computer system. This prevents an unauthorized attempt to start the car because only a valid key will be able to do so.

The technology is believed to be more secure than traditional keys for cars because it makes it harder for a thief 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 with transponder keys aren't safe from theft.

Key fobs are equipped with electronic chips inside them that communicate with the car's receiver using radio signals. The computer checks the code of the key with the database. If the codes match the car starts. If not, the vehicle will not start or fail to start.
