Electronic Car Key Repair Near Me
Modern car keys are not the basic metal pieces you can cut at self-service kiosks. They are sophisticated electronic devices that require specialized programming to function with your car's safety system.
Some are programmed by locksmiths, but others require sophisticated software that most dealerships do not have. Check your owner's manual for instructions, or locate a specialist in your area.
key fob repairs (also known as chip keys) comprise an electronic microchip embedded in the head of your car key. The antenna ring on the ignition lock transmits signals from the key to the computer system inside your car when you insert it into the ignition. The chip inside your car receives the signal and responds with an identification code, to confirm that the key is the correct one for the vehicle. Without this response, the car will not start.
This is a relatively new form of anti-theft technology, and it has proved effective in stopping theft. Transponder chips are found in all modern cars.
The key with a chip is usually thicker than the traditional flat keys made of metal, and will emit an electrical signal that is more powerful when it is inserted into the ignition cylinder. You can test the chip by wrapping a few layers of tin foil around the plastic part of the key, and then trying to start your car. If it doesn't work the key may have a transponder inside.
Most transponder key also include batteries to charge the chip. This battery can fail and cause the chip to stop working. This can cause your key to not longer turn off the immobilizer, or turn off the ignition. If you have transponder keys, it is important to replace the battery as soon as you can.
Transponder chips are more difficult to duplicate than a mechanical key. This means that the replacement key will likely cost a lot. It is recommended that you visit the local locksmith instead of going to the car dealership for this service. Locksmiths in your area have the tools and experience to program a transponder lock correctly for your car.
Certain transponder keys can be programmed at home, but the process is more difficult and requires a higher degree of knowledge regarding the security system of your vehicle. You could try this yourself if you own the proper equipment, but this is not recommended and could cause damage to the information stored on the chip in your vehicle.
Switchblade Keys
Car keys have evolved beyond the basic metal tools of yesteryear. Nowadays keys have additional security features designed to prevent unauthorized users from starting or unlocking your car. Understanding how the various types of car keys work will help you make informed choices when it comes to replacing or upgrading your key fob.
Traditional car keys have an all-metal key blade that works mechanically by inserting into the ignition cylinder, then opening the doors.

They are relatively inexpensive to replace if you lose them, however they are less secure than modern ones.
In the 1990s, automakers started using transponder keys to communicate with a sensor in the car's ignition. They are a more secure option because they require the car to be within the range of the sensor for the engine to start. This key is more difficult to duplicate because both sides are laser-cut. These keys are also referred to as "flip keys" or "transponder key". Certain car manufacturers use a similar cylindrical design called the Tibbe Key which is more difficult to duplicate.
Modern cars have keys that combine the traditional car key with an remote control. It appears like it's a key that has buttons to open doors, shut windows and to activate alarms.

Key Fobs
Since their introduction in 1990, key fobs are now an essential feature of cars. These small devices do much more than unlock doors and start cars and are also important anti-theft devices. Key fobs connect with vehicles and perform a variety of functions using radio signals. When remote key repair is pressed on the key fob, it transmits a signal that contains the unique code to a receiver located near the locking system of the vehicle. The receiver reads this code and performs any requested action, such as opening doors or even starting the car. Some key fobs can also be used to 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 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, which then energizes copper coils located on both sides of the device. These coils convert the energy of the RF into electricity, which powers a microcomputer chip inside the fob. The computer then transmits a digitized version of your car's unique ID number, which is confirmed by the receiver.
Many newer vehicles come with remote starters that allow the user to push a button on the fob to turn on the engine. In some cases you will have to insert a physical key into the ignition lock in order to start your vehicle. The majority of modern fobs have keys made of metal designed to work if the RF system fails.
If you need a replacement key fob for your vehicle, NAPA Auto Parts has a variety of key fobs from different brands that look and work as the original.

The most recent key fobs are also able to allow you to remotely control your car's other features, including windows. By pressing a button, you can roll down the sliding side-door window of your car. This is a great option when you're shopping at a busy mall and do not want to leave your car unattended when you're looking at the merchandise.
Trunk Lever Cylinder Locks
Over time, the locks on trunk levers may accumulate dirt, road grit, or corrosion. This could cause problems because the lock's internal components are small, precise parts that require minimal friction to function. Grit or dirt could cause the cylinder to become so blocked that the key won't turn when inserted. It's usually easy to fix this by spraying dry lubricant (Teflon(tm) or silicon, or graphite) into the cylinder. Spray the lubricant inside the cylinder, and then turn the key multiple times in both directions. The lock should be clean and be able to rotate with the key.
If the trunk doesn't open, the cylinder could be damaged and need to be replaced. A locksmith 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 have to replace the entire key assembly as well.
Sometimes, the issue is with the actuator for the trunk lock. This switch determines whether or not the lock opens after activation. A burnt fuse or wiring issue could cause this issue, and it's best to have a professional check the problem to see what needs to be addressed.
Instead of the carved keys of the past, most modern vehicles use laser-cut flip keys, which are fitted with a transponder chips to activate the ignition system and control other functions of your vehicle. Key fobs can also be used to open the trunk and glovebox as well as the rear hatch. Key systems like these can be more complex and difficult to troubleshoot compared to their predecessors.
If the key fob works perfectly but your trunk or another 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 skilled locksmith can 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 car lock cylinder.
