Key Fobs
Since their introduction in 1990 the key fob has become an integral part of cars. These tiny devices do more than unlock doors and turn on a car; they are also significant theft deterrents. Key fobs are able to communicate with vehicles and perform different functions by using radio signals. When a key fob is pressed it transmits a coded signal to a receiver close to the lock system of the vehicle. The receiver interprets the code and performs the requested action, such as unlocking the doors or starting the engine. Key fobs may also control other functions, for example, activating the car's panic alarm system or disarming and arming the security system.
The radio frequency (RF) signals utilized by key fobs are similar to the signals utilized by cell phones. When the key fob is within range of a receiver it emits a brief burst that is energized by the copper coils on either side of the device. The coils convert the energy from the radio into electricity, supplying power to a microcomputer embedded in the fob. The computer transmits a digital version of the unique ID number of your car which is then verified by the receiver.
Many newer vehicles come with remote starter systems that allow you to push a button on the fob to turn on the engine.

Over time, trunk lever locks will accumulate dirt, road grit or even corrosion. This could be a problem due to the fact that the lock's internal parts are tiny, precise components that require little friction to operate.

It's typically easy to correct this by spraying dry oil (Teflon(tm), silicon or graphite) into the cylinder. Spray the lubricant into the cylinder, and then turn the key multiple times in both directions. The lock should be clean and able to turn with the key.
If the trunk is still not opening it could indicate that the cylinder has been damaged and must be replaced. Locksmiths can repair your key cylinder and reprogram it to work with the lock. If the cylinder was damaged during a burglary or accident, you might need to replace the entire key assembly too.
