Electronic Car Key Repair Near Me Modern car keys aren't the simple metal pieces you can cut at self-service kiosks. They are sophisticated electronic devices which require special programming in order to work with your car's security system. Locksmiths can program some programs, but more sophisticated tools are required by many dealerships. Look through your owner's manual to find instructions, or locate a professional in your area. Transponder Keys Transponder keys (also known as chip keys) comprise an electronic microchip embedded within the head of your car key. The antenna ring on the ignition lock transmits a signal from the key to the computer system of your car when you insert it into the ignition. The chip inside your car detects the signal and responds with a unique code to confirm that the key is the right one for the vehicle. The car will not start without this confirmation. This is a relatively new kind of anti-theft technology, and it has proven to be effective in stopping theft. The majority of modern vehicles are equipped with transponder chips. The key with a chip is usually thicker than the traditional flat keys made of metal and will emit an electric signal with more power when it's inserted into an ignition cylinder. You can test your chip by wrapping a few layers of thin aluminum foil over the plastic portion of the key before trying to start your car. 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 required to operate the chip. However, this battery can be damaged over time, causing the chip to stop functioning. This can result in your key not being able to longer activate the immobilizer or turn off the ignition. It is important to replace the battery as quickly as you can, if you have a transponder. Transponder chips can be more difficult to duplicate than mechanical keys. This means that a replacement key is likely to be expensive. It is recommended that you go to a local locksmith instead of going to the car dealership for this service. Local locksmiths are more likely to have the equipment and know-how required to correctly program the new transponder key to your car. Some transponder key can be programmed in-house, however the process is more complicated and requires a greater level of understanding about your vehicle's security system. If you have the proper equipment, you can do it yourself. However, this is not recommended because it could corrupt the information stored on the chip in your car. Switchblade Keys Car keys have evolved beyond the basic metal implements of yesteryear. Now key fobs come with additional layers of security designed to prevent non-authorized users from opening or unlocking your car. Understanding how different kinds of car keys work helps you make educated decisions regarding key fob replacements or upgrades. The standard car key is an iron blade that is operated mechanically by inserting it into the ignition door cylinder to open it. In contrast to transponder keys they do not communicate with the computer in the car. Certain vehicles, especially older models, still have these keys. They are relatively cheap to replace should you lose them, however they are less secure than modern alternatives. In the 1990s, automakers began using transponder keys to communicate with a sensor inside the ignition of the car. They are a more secure option because they require that the vehicle be within range of the sensor for the engine to start. This type of key is also difficult to duplicate, as it is laser cut on both sides. These keys are also referred to as “flip keys” or “transponder key”. Some car brands utilize a similar design, referred to as a Tibbe Key that is more difficult to duplicate. Modern cars have a key fob which combines the traditional car key with an remote control. It appears like a key with buttons to open doors, lower windows and to activate alarms. Some keys have a spring-loaded switchblade-like type of key that folds into an accessory. If you lose this type of key, you'll need to go to the dealership to purchase a new one and then have it electronically linked with your car. The cheapest method to get an old key replaced is through an auto locksmith. They can usually offer you a new key and have it programmed on the moment of the call. The cost will be considerably cheaper than a dealership, but it may take longer if the new key needs to be ordered for your vehicle. If you don't want to rush or don't want to pay the extra cost, you can utilize roadside assistance or your car insurance provider. Key Fobs Since their introduction in the year 1990, key fobs are now a standard feature of automobiles. These small devices are more than an instrument to unlock doors and start the vehicle. They also act as a significant theft deterrent. Key fobs utilize radio signals to communicate with the vehicle and perform various functions. When the button is pressed on the key fob it transmits a signal with an unique code to a receiver located near the vehicle's locking system. The receiver interprets the code and performs any requested action such as unlocking doors or starting the car. Some key fobs can also be used to control other functions for example, activating the car's panic alarm system, or disarming and arming the security system. The radio frequency (RF), signals used by key fobs are similar in nature to those that are used by cell phones. When the key fob is in the range of a receiver it emits a brief burst of energy that energizes copper coils located on both sides of the device. These coils convert energy from radio waves into electrical energy which powers a microcomputer chip in the fob. The computer transmits a digitalized version of the unique ID number of your car, which is then verified by the receiver. Many of the latest vehicles are equipped with remote starter systems that allow users to press a button on the fob to turn on the engine. In some instances, you'll still need to insert an actual key into the ignition lock in order to start your vehicle. The majority of modern fobs have keys made of metal that is designed to work in the event that the RF system is not working. If you need an alternative key fob for your vehicle, NAPA Auto Parts has an array of fobs from different brands that look and work like the original. Some of these fobs are programmable at home with an app from the car maker or a third party developer. Certain replacement fobs are only programmable at a dealer, as they require special software and technical knowledge. Many of the more modern key fobs can be used to control other features in your car, such as its windows. By pressing a button, you can roll down the sliding side-door window of your vehicle. This is helpful when you're shopping at a busy mall and do not want your car to be left unattended. Trunk Lever Cylinder Locks Over time the cylinder locks on trunk levers may collect road grit, dirt or corrosion. This could cause problems due to the fact that the lock's internal components are small, precise components that require little friction to operate. Grit or dirt can cause the cylinder to be so clogged that the key won't turn when inserted. It's often easy to correct this by spraying a dry lubricant (Teflon™, silicon or graphite) into the cylinder. Spray the lubricant into cylinder and then turn the key several times in both directions. TheKeyLab should be clean and should be able to turn using the key. If the trunk is not opening it could indicate that the cylinder is damaged and will need to be replaced. Locksmiths can replace your key cylinder and program it to work with the lock. If the cylinder was damaged during a break-in or by accident, you may need to replace the entire car key assembly as well. Sometimes, the issue is caused by the actuator for the trunk lock or switch that determines the release of the lock when it is activated. This issue could be caused by a burned fuse or faulty wiring. It is best to seek out a professional to determine what needs to happen. Modern cars, in contrast to the keys made of carved metal from the past, utilize laser-cut keys with chip that activates the ignition and controls other functions of your car. The key fob is also used to open the trunk or glovebox, or the rear hatch. These key systems are more complex and difficult to repair in comparison to their predecessors. If your key fob functions well, but the trunk or other lock doesn't work, it's best that you quit the car and call an automotive locksmith. They can determine the problem. A skilled locksmith can quickly program the key fob in order to work with a different lock, take out any obstructions to the lock's pins and tumblers or disassemble and replace the cylinder of your car lock.
