Key Fobs
Key fobs have become a standard automobile feature since their introduction in the 1990s. These small devices do much more than just unlock doors and start a car; they are also significant anti-theft devices. Key fobs make use of radio signals to communicate with the vehicle and perform a variety of functions. When the key fob is pulled it transmits an encoded signal to a receiver close to the vehicle's lock system. The receiver interprets this code and performs the desired action such as unlocking doors or launching the car. Some key fobs can be used for performing other functions like activating a panic alarm or disarming or arming the security system.
The radio frequency (RF) signals used by key fobs are similar to the ones used by cell phones. When the key fob is within the range of a radio receiver it sends a small burst that energizes the copper coils that are located on either side of the device. These coils convert energy from the radio into electricity, powering a microcomputer embedded in the fob. The computer transmits a digitalized version of the unique ID number of your car which is later verified by the receiver.
Many newer cars are equipped with remote starters that allow the user to press the button on a fob to start the engine.

Trunk Lever Cylinder Locks
Over time the cylinder locks on trunk levers can collect road grit, dirt or even corrosion. This can cause a problem due to the fact that the lock's internal components are small, precise components that require minimal friction to operate. Grit or dirt could cause the cylinder to be so clogged that the key will not turn when it is inserted. This can be corrected by spraying a dry fluid into the cylinder (TeflonTM or graphite, silicon or). Spray the lubricant into the cylinder, then turn the key several times in both directions. The lock should now be free of debris and able to turn with the key.
