Electronic Car Key Repair Near Me
Modern car keys aren't the simple pieces of metal that you can cut at a self-service kiosk. They're highly sophisticated electronic devices that require specific programming to work correctly with your car's security system.
Some are programmed by locksmiths, but others require advanced programming tools that many dealerships do not have. You can find instructions in the owner's manual or by contacting a local expert.
Transponder Keys
Transponder keys, also referred to as chip keys, are comprised of an embedded electronic microchip in the head made of plastic. When you insert the key into the ignition cylinder, it transmits a signal your car's computer system through an antenna ring on the ignition cylinder lock. The chip inside your car detects the signal and responds with a unique code confirming that the key is the correct one for the vehicle. The car will not start without this response.
This is a relatively new kind of anti-theft technology, and it has proven effective at deterring theft. Modern cars are equipped with transponder chips.
The key with a chip is generally thicker than flat metal keys and emits an electrical signal that is more powerful when it's inserted into the ignition cylinder. You can test the chip by wrapping a few layers of aluminum foil around the plastic portion of the key before trying to start your car. If it fails the key may have an internal transponder.
Most transponder keys also have batteries that supply the power to operate the chip. This battery can break and cause the chip to stop working. If this occurs your key will no longer operate the ignition or turn on the immobilizer inside your car. If you own transponder keys it is crucial to get the battery replaced as soon as possible.
Transponder chips can be more difficult to duplicate than a mechanical key. This means that the replacement key is likely to be expensive. It is recommended to visit a local locksmith instead of visiting the car dealership to get this service. Local locksmiths have more tools and experience to program a transponder key correctly for your vehicle.
Some transponder keys can be programmed on-board, but this procedure is typically more complicated and requires a greater level of understanding of your specific vehicle's security system. You could try this yourself if you own the proper equipment, but this isn't recommended and may corrupt the information on the chip in your vehicle.
Switchblade Keys
The keys to your car from the past are no longer the simple metal objects that they once were. Nowadays key fobs come with additional security features built-in that stop non-authorized users from opening or locking your vehicle. Understanding how the various types of car key work will allow you to make informed decisions when upgrading or replacing your key fob.
The traditional car key has a metal blade that is operated mechanically by inserting it into the ignition piston to open the doors. They don't communicate with the computer of the car unlike transponder keys. Certain cars, especially older models, still have these keys. They are fairly inexpensive to replace, however they are less secure than the modern alternatives.
In the early 1990s, automakers started using transponder keys that communicates with a sensor located on the car's ignition. They are more secure because the car must be within the range of a sensor to start the engine. This key is more difficult to replicate, as both sides are laser-cut. These keys are commonly referred to as "flip key" or "transponder keys." Certain automakers also use the same cylindrical design of keys, called the Tibbe key which is harder to duplicate.
Most modern cars have keys that combine the traditional car key with remote control. It resembles an advanced key that has buttons that open doors, roll down windows, and activate the alarm. Some also come with an electronic key that folds into the fob like the shape of a switchblade. If you lose the key, you'll have to visit the dealer to purchase a replacement and then have it electronically connected to your car.
The cheapest way to get an old key replaced is through an auto locksmith. They will usually provide you with a new key and have it programmed on the on the spot. The cost is significantly cheaper than at a car dealership, however it could take longer if they need to purchase the right key for your vehicle. If you don't want to be in a hurry or don't need the cost, you can use roadside assistance or your car insurance provider.
Key Fobs
Key fobs have become a common automobile feature since their introduction in the 1990s. These small devices are more than a way to unlock doors and start the car. They also act as a powerful deterrent to theft. Key fobs are able to communicate with vehicles and perform different functions by using radio signals. When you press a button on the key fob, it transmits a signal containing an unique code to a receiver located near the vehicle's locking system. The receiver interprets the code and executes the requested actions, like unlocking doors or starting the car. Some key fobs also control other functions, like activating the vehicle's panic alarm system or disarming and arming the security system.
The radio frequency (RF) signals used by key fobs are akin to the ones that are used by cell phones. When the key fob is within the range of a radio receiver it sends out a short burst of energy that activates the copper coils located on either side of the device. These coils convert the energy of the RF into electricity, which powers 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 you to press a button on a fob to start the engine. In certain instances, however, you'll still need a physical key to insert into the ignition lock to turn on your vehicle. Most newer fobs also come with a tiny metal key that is designed to work in the event that the RF system fails.
NAPA Auto Parts offers a range of key fobs that are compatible with your car. They are available in various brands and appear the same as the original. Some of these fobs can even be programmed at home by using an application available from the car manufacturer or a third-party developer. Other replacement fobs cannot be programmed in a dealership, as they require software and expertise that is exclusive to dealers' service department.

With a single touch, you can open the sliding side-door window of your vehicle. key repairs can be handy if you're shopping at an area that is crowded and you don't want to leave your car unattended when you're looking at the merchandise.
Trunk Lever Cylinder Locks
Over time, trunk lever cylinder locks can build up road grit, dirt or corrosion. This can cause a problem because the lock's internal components are small, precise parts that require only minimal friction to function. Dirt or grit can cause the cylinder to become so clogged that the key will not turn when it is inserted. This can be resolved by spraying a dry, oil-based lubricant into the cylinder (TeflonTM silicon, graphite or TeflonTM). Spray the lubricant inside 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 must be replaced. Locksmiths can replace the cylinder and reprogram your car key to work with the new lock. If the cylinder was destroyed in a burglary or accident, you might need to replace the entire key assembly as well.
Sometimes the issue is the trunk lock actuator. The switch controls whether the lock will release upon activation. This problem can be caused by an ignited fuse or defective wiring. It is best to consult a professional determine what needs to happen.
Modern cars, in contrast to the keys made of metal that were carved in the past, have laser-cut keys that have a chip that activates the ignition and controls other functions of the 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 more difficult to diagnose than their predecessors.
If your key fob works well, but the trunk or other lock doesn't work it's best to get out of the car and contact an automotive locksmith. They can determine the cause. A locksmith with the right abilities can quickly reprogram the key fob so that it can work with a different type of lock, remove any obstructions to pins and tumblers in the lock, or remove the car lock and then replace the cylinder.
