Transponder Keys
Transponder keys (also called chip keys) contain an electronic micro-chip embedded in the plastic head of your car key. The antenna ring on the ignition lock transmits signals from the key to the computer system of your car when you insert it into the ignition. The chip in your car detects the signal and responds with an identification code. This proves that the key you're using is the correct one for your vehicle. The car won't start without this response.
This is a relatively recent form of anti-theft tech however, it has proven effective in stopping theft. Most modern cars come equipped with transponder chips.
The key that has the chip is usually thicker than a traditional flat metal key, and will emit a stronger electrical signal when inserted into the engine. You can test the chip by wrapping the plastic part of your key in a few layers of tin foil before trying to start the engine. If it doesn't work it's likely that the key has a transponder inside.
Most transponder keys also have batteries that provide the power to operate the chip. However, the battery could be damaged over time, causing the chip to cease working. This can cause your key to not longer turn off the immobilizer, or turn off the ignition. If you have a transponder key it is essential to replace the battery as soon as you can.

It is recommended to visit a locksmith rather than your dealer to get this service. key repairs are more likely have the tools and knowledge required to correctly program the new transponder key to your car.

Switchblade Keys

Now key fobs come with additional layers of security built in that prevent unauthorized users from starting or locking your vehicle. Understanding how different kinds of car keys function can help you make educated decisions when it comes to replacing or upgrading your key fob.
Traditional car keys feature a key blade made of metal that works mechanically by inserting the ignition cylinder, then opening the doors. They do not communicate with the computer in the car unlike transponder keys. These kinds of keys are still common in certain cars, particularly older models. They are fairly inexpensive to replace, but they are less secure than modern alternatives.
In the 1990s, automakers began using transponder keys to communicate with a sensor inside the car's ignition. They are more secure since the car must be within the range of a sensor in order to start the engine. This key is more difficult to copy because both sides are laser-cut. Keys like this are often referred to as "flip key" or "transponder keys." Certain car brands also use a similar cylindrical key design, called the Tibbe key which is harder to duplicate.
Modern cars have key fobs that combine the traditional car key with a remote control. It looks like an advanced key with buttons that can open doors, open windows, roll them down and set off the alarm. Some keys come with a spring-loaded switchblade-like type of key that folds into a fob. If you lose this kind of key, you'll need to visit a dealership to purchase a new one and have it electronically connected to your vehicle.

Key Fobs
Since their introduction in the year 1990 Key fobs have become a standard feature of automobiles. These tiny devices can do more than just unlock doors and start cars and are also important theft deterrents. Key fobs connect with vehicles and perform a variety of functions using radio signals. When the key fob is pulled it transmits a coded signal to a receiver near the lock system in the vehicle. The receiver interprets the code and executes the requested action like unlocking the doors or launching the engine. Certain 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 used by cell phones. When the key fob is within the range of a receiver, it emits a brief burst that is energized by the copper coils located on either side of the device. The coils convert the 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 number, which is confirmed by the receiver.
Many modern cars are equipped with remote starters which allow you to push a button on a fob to start the engine. In certain instances, you'll have to insert an actual key into the ignition lock to start your car. The majority of newer fobs come with a small metal key that's designed to work in the event that the RF system fails.
NAPA Auto Parts offers a variety of key fobs that are compatible with your vehicle. They come in different brands and appear the same as the original. Some of these are easily programmed at home with an application from the manufacturer of the car or a third party developer. Certain replacement fobs are only programmed by a dealer because they require specialized software and technical expertise.
Many of the more modern key fobs can be used to control other features on your vehicle like windows. With a single touch, you can roll down the side-door windows of your vehicle. This is a great option when you're shopping at the mall that's busy and do not want to leave your car unattended while you're looking at the merchandise.
Trunk Lever Cylinder Locks
Over time, the locks on trunk levers can collect dirt, road grit or even rust. This could be a problem because the lock's internal parts are small, precise components that require minimal friction to function. Grit or dirt in the cylinder may cause enough resistance to prevent the key from turning when it's inserted. It's usually easy to fix this issue by spraying a dry lubricant (Teflon(tm) or silicon, or graphite) into the cylinder. Spray the lubricant into the cylinder, and then turn the key several times in both directions. The lock should now be free of debris and be able to rotate with the key.
If the trunk is still not opening it could indicate that the cylinder has been damaged and will need to be replaced. Locksmiths can replace your key cylinder and reprogram it to work with the lock. If the cylinder is damaged by a burglary, or a collision, you may also need to replace the car key assembly.
Sometimes the issue is the trunk lock actuator. This switch controls whether the lock will release upon activation. A burnt fuse or wiring issue may mimic this problem and it's best to let a professional check the problem and determine what needs to be addressed.
Modern cars, in contrast to the keys made of carved metal from the past, use laser-cut keys with chips that trigger the ignition and controls other functions of your vehicle. The key fob can also be used to open your trunk, glove box, or rear hatch. These key systems can be more complicated and difficult to repair as compared to their predecessors.
If your key fob functions perfectly, but the trunk or other lock doesn't work it's best to quit the car and call an automotive locksmith. They can identify the cause. A skilled locksmith can quickly reprogram the key fob to work with a different lock, take out any obstructions to the lock's tumblers and pins, or remove and replace the cylinder of your car lock.
