Keyless Entry System

When you park your car, it's common to be a bit niggling, "have I locked the car?" With keyless entry you don't have to worry about leaving the car locked, as once you've walked a set distance away from the vehicle it will lock itself. You will usually have press the button on the remote key fob to activate this feature, but some systems let you activate it by walking close to the vehicle.

Most systems emit radio signals that are detected by the key fob. The key fob transmits an alert back to the vehicle, informing the onboard computer that the user is close enough the key to allow doors to be opened. Certain systems are dual-way, meaning they also transmit status information to the driver on a small screen inside the car, like battery levels, window down/up status, and diagnostic data.

It is essential to read through the manual for each system, as they are all different and have different wiring specifications. Also, make sure to disconnect the car's battery prior to altering electrical connections. Use high-quality batteries that are rated according to the amount of power required by the system. The wrong type of car battery could damage the electronics. It is also essential to store batteries in a safe place which is safe from moisture and heat.

Transponder Chip

A transponder, also called"chip-key," or "chip-key," is a feature that stops theft from the ignition of your car. This is one of the more secure ways to protect your car from theft since it ensures that only your keys will start your vehicle. When you insert a car key with the transponder chip in your ignition, it sends an electronic signal to a small antenna ring that is placed on your car's engine. The engine control unit (ECU) which controls the car, will then verify that the signal was sent from the original keys. If the ECU does not receive this message it will remain in a state of immobility and locked.

This is similar to the way military planes utilize codes to identify themselves on radar. This is how the transponder chip was developed for cars, and it has helped in reducing theft of vehicles in the United States.

A transponder is a small microchip that is built into the head of your car keys. It's also referred to as a chip-key, and is used in a majority of cars made within the last 15 years. The name derives from the electronic microchip embedded into the plastic head of your key. Transponder keys are more difficult to duplicate than flat metal keys which do not contain any technology. A locksmith must employ specialized equipment to copy the transponder key that is already in your vehicle.

Remote Key Fob

A key fob, also known as a remote, is a small device that opens your car's doors and in some instances, even starts it remotely. It also comes with an embedded security chip or transponder. Most fobs feature several buttons that can perform various functions, from locking your doors, opening your trunk and to start your car. Fobs are typically attached to your keychains and come in several shapes and sizes.

Some older key fobs can be programmed by the user, however most require locksmith or dealership programming using a computer program. The programs are different for car models, brands and years. The key fob transmits its unique digital identification code to the onboard computer of the car when it is programmed. The computer stores this code, which makes it impossible to unlock the car's door using a different fob.

Some of the newer key fobs are able to let you roll down your car's window. This is especially handy in the event that you've had to maneuver your car into a tight parking spot. It's also helpful when you need to cool your vehicle down on the hottest day of summer without having to walk out. You can use a key fob activate the panic button in certain automobiles. The button will make blaring noises that scare away burglars. It's a good idea to keep your key fob by your bedside to help prevent home burglaries as well according to Consumer Reports.

Door Locks

Door locks should be compliant with the regulations for fire and building as well as industry or customer-specific security requirements. These can include accessibility for people with disabilities, security during an earthquake, blast resistance, retraction of deadbolt torque, as well as the durability of the lock.

A door lock cylinder is a metallic tube that holds a bolt, which extends from the cylinder and secures the door. It also engages spring-loaded pins that prevent the cylinder from rotating. When a key is inserted in the lock, the notches on the key will raise the pins to the correct height to place them within the cylinder housing. When all pins are located in the proper places they form what's called a shearline. This prevents the bolt and cylinder from rotating and locking the door.

To reset the autolock system, hold the lock and unlock buttons on the fob of the key for approximately 60 minutes. This resets the sensor, allowing the doors, fuel-fill lid and liftgate to lock themselves automatically when the ignition switch is turned off. Go to the Settings section in the Mazda Connect Owner's Manual to alter the automatic lock/unlock setting. The warning lights and horns blink to indicate that the automatic lock function has been turned on.
