Electronic Car Key Repair Near Me
Modern car keys aren't basic pieces of metal you can get cut at a self service kiosk. They're highly sophisticated electronic devices that require specialized programming to function properly with your car's security system.
Some can be programmed by locksmiths, but others require sophisticated tools for programming that a lot of dealerships do not have. You can find instructions in the owner's manual or by contacting a local expert.
Transponder Keys
Transponder keys (also known as chip keys) comprise an electronic microchip embedded in the plastic head of your car key. When you insert the key into the ignition cylinder, it sends a signal to the computer system of your car via an antenna ring on the lock of the ignition cylinder. The car's computer detects the signal and responds with an identification code. This confirms that the key you are using is the correct one for your car. The car won't start unless this response is received.
This is a relatively new technology for preventing theft however, it has proven effective in stopping theft. Modern cars are equipped with transponder chips.
The key with a chip generally thicker than flat metal keys and emits an electric signal with more power when it's inserted into the ignition cylinder. You can test the chip by wrapping a few sheets of tin foil around the plastic portion of the key and then trying to start the car. If it doesn't work it's likely that the key has a transponder in it.
The majority of transponder keys also have a battery to charge the chip. However, this battery may be damaged over time, causing the chip to cease working. This will cause your key to not longer activate the immobilizer or turn the ignition. If you own a transponder key it is essential to get the battery replaced immediately.
Transponder chips are more difficult to duplicate than mechanical keys. This means that a replacement key will likely cost a lot. It is recommended to go to a local locksmith instead of visiting the car dealership to get this service. Local locksmiths are more likely have the tools and expertise needed to properly program the new transponder key to your vehicle.
Certain transponder keys can be programmed in-house, however the process is more complex and requires a higher degree of knowledge regarding your vehicle's security system. If you have the right equipment, you can perform it yourself. However, car key repair is not recommended as it could cause damage to the data on the chip in your car.
Switchblade Keys
Car keys have evolved beyond the basic metal instruments of the past. Today, many key fobs have additional security features designed to prevent non-authorized users from opening or locking your vehicle. Understanding how different types of car keys function can help you make informed decisions about key fob replacements or upgrades.
The standard car key is an iron blade that operates mechanically by inserting it into the ignition cylinder to open the doors. Unlike transponder keys, they don't communicate with the computer in the car. These types of keys are still found in certain cars, particularly older models. They are fairly inexpensive to replace if you lose them, but they are less secure than modern keys.
In the 1990s, automakers started using transponder keys to communicate with a sensor in the ignition of the car. They are a safer option due to the fact that they require the car to be within the range of the sensor in order for the engine to begin. This key is more difficult to duplicate since both sides are laser-cut. These keys are commonly referred to as "flip key" or "transponder keys." Certain automobile manufacturers also have a similar cylindrical key design known as the Tibbe key that is more difficult to duplicate.
The majority of modern cars have keys that are able to combine a traditional car key and a remote control. It resembles 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 key that folds up into fob. If you lose this kind of key, you'll need to go to the dealership to purchase a replacement and have it electronically paired to your vehicle.
An auto locksmith is the cheapest alternative to replace a key. They will usually offer you a new key and have it programmed right on the moment of the call. The cost is much lower than a dealership, but may take longer if they have to purchase the right key for your vehicle. If you're not in a rush and don't need the extra cash roadside assistance or your insurance provider can help.
Key Fobs
Since their introduction in the year 1990, key fobs are now a standard feature of automobiles. These tiny devices are much more than a way to unlock doors and start the car. They also function as a significant theft deterrent. Key fobs communicate with vehicles and perform various functions by using radio signals. When the key fob is pressed it sends the coded signal to a receiver near the vehicle's lock system. The receiver interprets the code and executes the requested action such as unlocking doors or launching the car. Certain key fobs can be used for controlling other functions, such as activating a panic alarm, or disarming/arming the security system.
The radio frequency (RF) signals used by key fobs are the same as those that are used by cell phones. When the key fob comes within the range of a radio receiver it sends out a short burst of energy that activates the copper coils that are located on either side of the device. The coils convert the energy from radio waves into electrical energy which powers a microcomputer chip inside 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 let 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 in order to start your vehicle. Most newer fobs also come with a small key made of metal that is 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 car. They are available in a variety of brands and look exactly the same as the original. Some of these fobs are programmable at home with an application from the car maker or a third party developer. Other replacement fobs cannot be programmed at a dealership since they require software and technical expertise that is exclusive to dealers' service department.
The majority of modern key fobs are also designed to remotely control your vehicle's other features, such as the windows. When you press a button on your fob will cause the car's sliding side windows to roll down. This is helpful if you are shopping in a busy mall and don't want your car to be left unattended.
Trunk Lever Cylinder Locks
Over time, trunk lever cylinder locks may accumulate dirt, road grit or even corrosion. This can cause problems because the internal parts of the lock are tiny, precise components that require little friction to function. Grit or dirt in the cylinder may cause enough resistance to stop the key from turning when being inserted. This can be corrected by spraying dry oil-based lubricant into the cylinder (TeflonTM silicon, graphite or TeflonTM). Spray the lubricant into the cylinder, and then turn the key several times in both directions. The lock should be clear of obstructions and turnable using the key.
If the trunk still won't open, the cylinder might be damaged and must be replaced. A locksmith can replace the cylinder and reprogram your car key to work with the new lock. If the cylinder is damaged in a break-in or a collision, you may also need to replace the car key assembly.
Sometimes, the problem is caused by the actuator for the trunk lock or switch that determines whether the lock releases when activated. This issue could be caused by burning fuse or damaged wiring. It is recommended to seek out a professional to determine what is required to be done.
Modern cars, unlike the carved metal keys from the past, use laser-cut keys and chips that trigger the ignition and also controls other functions of the vehicle. Key fobs can also be used to open the trunk, glovebox or rear hatch. These key systems can be more complicated and difficult to fix compared to their predecessors.
If the key fob works perfectly but your trunk or other lock isn't working, it's best to leave the car and call an automotive locksmith to figure out the root of the issue. A professional locksmith will be able to quickly re-program the key fob to work with a different lock, remove any obstructions that are blocking the lock's pins and tumblers or disassemble and replace the cylinder of your car lock.
