electronic car key repair near me - he said -
Modern car keys aren't simple pieces of metal you can cut at a self-service kiosk. They're advanced electronic devices that require special programming to work correctly with your car key remote repair's security system.
Locksmiths can program certain programs, but more sophisticated tools are required by many dealerships. The instructions are available in your owner's manual, or by contacting a local specialist.
Transponder Keys
Transponder keys, also referred to as chip keys, have an embedded electronic microchip in the plastic head. The antenna ring on the ignition lock transmits signals from the key to the computer system in your car when you insert it into the ignition. The car's computer detects the signal and responds with an identification code. This is a confirmation that the key you are using is the correct one for your car. The car will not start unless this response is received.
This is a relatively new type of anti-theft technology, but it has proven to be effective in stopping theft. Transponder chips are present in the majority of modern vehicles.
The key with a chip is usually thicker than the traditional flat keys made of metal and emits a more powerful electrical signal when it is inserted into the ignition cylinder. You can test the chip by wrapping the plastic part of your key with some tin foil before trying to start the engine. If it doesn't work it's likely that the key has an internal transponder.
Most transponder keys also contain batteries that supply the power needed to operate the chip. However, this battery can be damaged over time, causing the chip to cease working. This will cause your key to no 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 aren't as easy to duplicate like an ordinary mechanical key, so getting an entirely new key can be expensive. You should seek out a locksmith rather than your car dealer for this service. Locksmiths in your area have the tools and expertise to program a transponder key properly for your vehicle.
A transponder key may be programmed at home, but the process is more complicated and requires a greater level of understanding about your vehicle's security system. You can attempt to do this yourself if you own the right equipment, however this isn't recommended and could cause damage to the information stored on your car key repair service's chip.
Switchblade Keys
The car keys of the past are no longer the simple metal objects they once were. Today, many key fobs have additional security layers built in that prevent non-authorized users from opening or locking your vehicle. Understanding how the various types of car keys function will help you make informed choices when it comes to replacing or upgrading your key fob.
Traditional car keys feature an all-metal key blade that operates mechanically by inserting it into the ignition cylinder and opening the doors. Contrary to transponder keys, these keys do not communicate with the car's computer. Certain vehicles, especially older models, still use keys that are not transponder compatible. They are relatively cheap to replace should they are lost, but they are less secure than modern keys.
In the 1990s automakers began using transponder keys that communicates with a sensor in the ignition of the car. They are a safer option since they require the car to be within range of the sensor in order to allow the engine to start. This key is more difficult to duplicate since both sides are laser-cut. Keys like this are also referred to as "flip keys" or "transponder key". Certain car manufacturers utilize a similar design, referred to as a Tibbe Key which is more difficult to duplicate.
Modern cars come with keys that combine the traditional car key with an remote control. It looks like a key with buttons to open doors, roll windows down and to activate alarms. Some keys come with a spring-loaded switchblade-like key that folds up into a fob.

Key Fobs
Since their introduction in the year 1990, key fobs are now an essential feature of cars. These small devices do much more than unlock doors and start a car they also serve as significant security measures against theft. Key fobs use radio signals to communicate with the vehicle and carry out various functions. When the button is pressed on the key fob it transmits a signal with the unique code to a receiver near the locking system of the vehicle. The receiver interprets this code and executes the requested actions, like unlocking doors or starting the car. Certain key fobs can be used for controlling other functions such as activating a panic alarm or disarming or arming the security system.
The radio frequency (RF) signals utilized by keyfobs are similar in nature to those used by cell phone. When the key fob is in the range of a receiver it sends out a tiny amount of energy, which energizes copper coils located on both sides of the device. These coils convert energy from the radio into electricity, powering the microcomputer inside the fob. The computer then transmits a digitized version of the unique ID number of your car that is then confirmed by the receiver.
Many of the latest vehicles are equipped with remote starter systems that allow the user to push a button on the 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 majority of modern fobs have small, metal keys designed to work if 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 work and look as the original.

Trunk Lever Cylinder Locks
Over time, trunk lever locks will accumulate dirt, road grit, or corrosion. This can lead to a problem due to the fact that the lock's internal components are tiny, high-precision parts that require minimal friction to function. Grit or dirt in the cylinder may cause enough resistance to prevent the key from turning when placed. This can be fixed by spraying a dry, lubricant into the cylinder (TeflonTM or graphite, silicon or). Spray the lubricant into cylinder, and then turn the key several times in both directions. The lock should be free of any obstructions and can be turned with the key.
If the trunk still won't open, the cylinder could be damaged and must be replaced. A locksmith can replace your cylinder and reprogram the key to work with the lock. If the cylinder was destroyed during a burglary or accident, you may need to replace the entire key assembly as well.
Sometimes, the issue lies caused by the actuator for the trunk lock which controls the release of the lock when activated. This issue could be caused by burning fuse or damaged wiring. It is best to consult a professional determine what is required to be done.
Instead of the carved keys of the past, most modern vehicles use laser-cut flip keys, which are fitted with a transponder chip that can activate the ignition system and control other functions on your vehicle.
