They are relatively inexpensive to replace if they are lost, but they are less secure than modern keys. In the 1990s, automakers began using transponder keys to communicate with a sensor in the ignition of the car. They are more secure since the car must be within range of a sensor in order to start the engine. This type of key is also difficult to duplicate, as it is laser cut on both sides.

Key Fobs Since their introduction in the year 1990, key fobs are now an essential feature of cars. These tiny devices are more than just an instrument to unlock doors and start the vehicle. They also act as a major deterrent to theft. Key fobs communicate with vehicles and perform various functions by using radio signals. When you press a button on the key fob it transmits a signal containing the unique code to a receiver close to the locking system of the vehicle. The receiver reads this code and performs any requested action, such as unlocking doors or starting the car. Some key fobs are capable of controlling other functions such as activating a panic alarm, or disarming or arming the security system. The radio frequency (RF), signals used by key fobs are similar to the signals that are used by cell phones. When the key fob comes within range of a receiver it sends out a short burst that energizes the copper coils located on either side of the device. These coils convert energy from radio waves into electrical energy that powers a microcomputer chip in the fob. The computer then sends a digitized version of your car's unique ID which is then verified by the receiver. Many newer vehicles are equipped with remote starter systems that let the user to push a button on the fob to start the engine. In some instances, however, you'll still require a physical key to insert into the ignition lock to turn on your car.

Trunk Lever Cylinder Locks Over time, trunk lever locks may accumulate dirt, road grit or corrosion. This can lead to a problem because the lock's internal parts are small, precise components that require minimal friction to function. Grit or dirt inside the cylinder can create enough resistance to stop the key from turning when it's inserted. It's usually easy to fix this by spraying dry lubricant (Teflon™ or silicon) or graphite) into the cylinder. Spray the lubricant in the cylinder and then turn the key several 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 be a sign that the cylinder is damaged and will need to be replaced. A locksmith can replace your key cylinder and reprogram it to work with the lock. If the cylinder was damaged by a burglary, or an accident, then you might also need to replace the car key assembly. Sometimes the issue is the actuator for the trunk lock. The switch controls whether or not the lock opens upon activation. A burned fuse or wiring issue may cause this issue, and it's best to let an expert examine the issue and determine what needs to be addressed. Instead of the carved keys that were used in the past, modern vehicles use laser-cut flip keys that come with a transponder chip to activate the ignition system and control other functions on your vehicle.

If the key fob is working fine but your trunk or other lock isn't functioning, it's best to leave the car and call an automotive locksmith to determine what's wrong. A locksmith with the appropriate abilities can quickly reprogram your key fob to ensure it works with a different type of lock, and remove any obstructions to pins and tumblers in the lock, or take out the car lock and then replace the cylinder.
