Transponder Keys
Transponder keys (also called chip keys) comprise an electronic microchip embedded within the head of your car key. When you insert the key into the ignition cylinder, it transmits a signal to your car's computer system through an antenna ring located on the ignition cylinder lock. The chip inside your car detects the signal and responds with an identification code, confirming that the key is the right one for the vehicle. If this response is not received the car will not start.
This is a relatively new type of anti-theft technology, but it has proven to be effective in stopping theft. Transponder chips can be found in the majority of modern vehicles.
key fob repair with a chip is generally thicker than flat metal keys and will emit a more powerful electrical signal when it's inserted into the ignition cylinder. You can test the chip by wrapping a few layers of thin aluminum foil over the plastic part of the key before trying to start the car. If it fails, the key probably has a transponder inside.
The majority of transponder keys include a battery to provide power to the chip. The battery could fail and cause the chip to stop functioning. This can cause your key to not longer be able to activate the immobilizer or turn off the ignition. It is important to replace the battery as quickly as you can if have a transponder.

Switchblade Keys
Car keys have evolved well beyond the basic metal implements of yesteryear. Today keys have additional security features designed to prevent unauthorized users from starting or locking your vehicle. Understanding how different types of keys work can help you make educated decisions regarding key fob replacements or upgrades.
The standard car key is an aluminum blade that is mechanically operated by inserting it into the ignition door cylinder to open it. Contrary to transponder keys, these keys do not communicate with the car's computer. Some cars, particularly older models, still use these keys. They are reasonably affordable to replace in the event that they are lost, but they are less secure than modern keys.
In the 1990s, automakers began using transponder keys that communicate with a sensor inside the ignition of the car. They are more secure because the vehicle must be within the range of a sensor in order to start the engine. This key is more difficult to replicate since both sides are laser-cut. These keys are commonly known as "flip key" or "transponder keys." Some automobile manufacturers also have the same type of key with a cylindrical design known as the Tibbe key which is harder to duplicate.
The majority of modern cars have keys that combine traditional car keys with an remote control. It appears like an ordinary key, with buttons that open doors, lower windows, and activate alarms. Some also include keys that are spring-loaded and fold into the fob, resembling the shape of a switchblade. If you lose this key, you'll need to go to the dealer to purchase a replacement and have it electronically paired to your car.

Key Fobs
Key fobs have become a standard automobile feature since their introduction in the 1990s. These small devices are much more than a way to unlock doors and start the vehicle. They also function as a significant theft deterrent. Key fobs use radio signals to communicate with the vehicle and carry out various functions. When you press a button on the key fob, it transmits a signal that contains a unique code to a receiver close to the locking system of the vehicle. The receiver reads this code and performs the desired actions, like unlocking doors or launching the car. Key fobs may also control other functions, such as 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 that are used 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 located on either side of the device. The coils convert the RF energy into electricity, which powers the microcomputer inside the fob. The computer transmits a digital 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 let you to press a button on a fob to start the engine. In some cases however, you'll require a key to insert into the ignition lock to turn on your car. The latest fobs are also equipped with a small key made of metal that's designed to work in the event that the RF system fails.
If you require a replacement key fob for your vehicle, NAPA Auto Parts has an array of fobs from various brands that function and look as the original. Some fobs are able to be programmed at home by using an app that is available from the car manufacturer or an independent developer. Other replacement fobs must be programmed at a dealership, as they require software and expertise that is exclusive to dealers' service department.
The most recent key fobs are also designed to remotely control your vehicle's other features, such as windows. By pressing a button you can open the sliding side-door window of your car. This is a great option when you're shopping at an area that is crowded and you don't want to leave your car unattended while looking at the merchandise.
Trunk Lever Cylinder Locks
Over time, trunk lever cylinder locks can collect road grit, dirt or corrosion. This can cause problems, as the internal parts of the lock are tiny, precise components that require minimal friction to function. Grit or dirt in the cylinder may cause enough resistance to stop the key from turning when being inserted. It's typically easy to correct this by spraying dry lubricant (Teflon(tm) or silicon, or graphite) into the cylinder. Spray the lubricant in the cylinder, then turn the key multiple times in both directions. The lock should now be free of debris and able to turn with the key.
If the trunk isn't open, the cylinder might be damaged and must be replaced. Locksmiths can repair your cylinder and reprogram the key to work with the lock. If the cylinder was damaged during a burglary or accident, you might need to replace the entire car key assembly as well.
Sometimes the issue is the trunk lock actuator. This switch controls whether the lock will release upon activation. This issue could be caused by an ignited fuse or defective wiring. It is recommended to consult a professional to determine what is required to be done.
Instead of the carved keys of the past, most modern vehicles use laser-cut flip keys that are equipped with a transponder chip that can activate the ignition system and control other functions on your vehicle. Key fobs can also be used to open the trunk or glovebox, or the rear hatch. These key systems are more sophisticated and are difficult to repair than their predecessors.
If your key fob is working fine, but the trunk or other lock doesn't work, it's best that you leave the car to call an automotive locksmith. They can identify the problem. A professional locksmith will be able to quickly program the key fob in order to work with a different lock. They can also remove any obstructions that are blocking the lock's pins and tumblers or take apart and replace the car lock cylinder.
