Transponder Keys

If you own a vehicle built in the past 20 years, it is likely that your key includes a transponder chips inside it. These chips are embedded inside the head of your key and are made to communicate with the computer system of your car when inserted into the ignition cylinder. This allows the car's computer to verify that the key is yours and disables the immobilizer so that only you can turn on the engine.

The chip in the car key is powered by an electromagnetic signal that is sent out by an unassuming coil that is attached to the key barrel. When the chip detects the signal, it transmits a response to the car. The computer recognizes it's your keys. This eliminates the chance of fraudulent key tampering and also deterring theft.

Many people turn to car dealerships when they want to get their keys copied. A professional locksmith can make copies of your transponder key for a fraction of the cost than a dealer.

You should always keep a spare transponder key in a safe location and away from your vehicle. It is useful if your car keys need to be replaced, or should one get lost. If you lose a transponder key, be sure to note the code number stamped on a plate attached to your keys. This information is required to program a replacement key, if needed.

Key Fobs

Key fobs can do much more than unlock your car door. The handy devices can be used to open your windows, summon your car to park it and auto-park it.

Fobs communicate with the door latch by using the radio system referred to as RFID. An RFID chip embedded in the fob emits a unique coded signal which matches with the reader's code in the door latch. When the signal is in sync, the door opens and grants access to the owner.

It shouldn't take you more than a couple of minutes to replace the battery. Most fobs come with a removable cover which makes it easy to replace the battery. The owner's manual will provide instructions on how to do this, and there are many online videos to assist with the process.

Remove the code-containing plates from the key fob. Note down this code number and store it in a safe location (not in your vehicle). Then, should you lose your Mazda key fob and you lose it, you'll have the key fob's code to use to order a new one from the dealer. You could be covered by your insurance, however, you'll need to pay the deductible. You can purchase key fobs from your local hardware store online, or from the big box store however, the dealer will usually be the cheapest.

Keyless Entry

Keyless entry is a useful feature that allows you to unlock your car without touching the door handle. It uses a radio signal to communicate between the key fob and the car. Key fobs can also be used to lock the car or start it. This technology is becoming more popular among all types of automobiles. Certain automakers include this technology in the cost of base of their vehicles, whereas others provide it as an option.

You can add this feature to your car at home. You will need to buy the tools and components needed. Be sure to purchase an instruction manual that will provide you with all of the information. The manual will guide you on which wires to connect. You will also require a wire stripper, or cutter along with a soldering machine and some electrical tape.


Once you have the required materials, you will need to disconnect the battery from the vehicle before starting. Then, you can remove the cover that is located under the steering wheel, to get access to the necessary wires. Label the wires you wish to connect. Use only the wires specified in the instructions. Wrap the wires exposed in black electrical tape.

Wear gloves if going to be doing the work yourself to prevent skin irritation. Save the code number of your key fob safely. This can be very useful when you need to program the system for the first time.

Ignition Cylinder

The ignition cylinder is the part in which you insert your vehicle key to start the engine. It is attached to the ignition and is an electrical component that locks and unlocks the engine through scanning the anti-theft code inside the key.

Over time the ignition cylinder could wear out or even wash out and stop functioning properly. This will usually lead to difficulty starting or recharging the vehicle. You might also notice that your key gets stuck in the ignition.

In most cases you will need to replace your ignition, not the key. This is a costly and complex procedure, particularly for vehicles with security systems which require the ignition cylinder to be replaced in order to function correctly.

It isn't always easy to change an ignition lock due to the fact that you need to remove the steering column and lower steering section cover in order to access the ignition lock. After this, you'll need to disconnect and isolate the negative battery wire to prevent any accidental connections during the replacement process.

When you've got all the tools needed, the removal process should be fairly straightforward. The next step is to reverse the method you used to remove the cylinder. Install it correctly so that the tab and the retaining slot are in alignment. You'll need to make sure that the tumblers are placed in the correct order.
