Sometimes you may find a car driving near you making entirely too much noise, most likely that car has a damaged exhaust system or a missing their muffler. A Muffler is used on internal combustion engines to lessen the amount of noise the engine makes.

A muffler is specially tuned to lessen the noise coming from the motor due to a remarkable feat of engineering, creating destructive interference to offset the engine noise. Mufflers are also used to reduce back pressure which decreases wear on the engine and boosts efficiency.

To begin we must learn why we hear the noise from the engine the way we do. The motor’s exhaust valves open and allow high pressure exhaust gases to escape into the exhaust system. Low pressure waves already in the exhaust stack with the high pressure waves and exit the exhaust system. Your eardrums vibrate when these sound waves reach them, which is how we hear the noise from a car engine.

By having a sound wave that is opposite the original sound wave, which is the simple description of a muffler’s function, the two sound waves then cancel each other out. The first sound wave is at its lowest point as the first sound wave is at its highest point, so your eardrum does not register the noise.

The muffler is designed and built in such a way that sound will be redirected before leaving the muffler. A secondary chamber inside the unit is a specified length and contains a specific amount of air that is calculated to create a wave to cancel out the sound wave from an engine.

Some mufflers function a different way, due to a different configuration. A cherry bomb or glass pack is the name of a muffler that uses a pipe filled with holes, wrapped in glass insulation and surrounded by a steel cover. Not as effective as the other type of muffler, it does not deaden the engine noise as much. People that want higher performance from their engine often choose to use this type of muffler.

A new type of muffler is being developed that will use microphones, a speaker and a computer to muffle engine exhaust noises. This sophisticated system is known as active noise canceling.The first microphone picks up the exhaust noise, the computer generates a noise to cancel the original sound wave. The second microphone listens and reports back to the computer so any needed adjustments can be made. These systems are mainly used on industrial generators today.

I hear that I can keep the old locks I replace and buy a new cylinder and program it to the lock I need. I am just not sure what is the cheapest way. I have already looked at barginlocks.com and similar sites.

If I buy a used transponder key from ebay that’s been used with another car can it be reprogrammed? Can the chip be replaced? If so, any ideas on how or where? Thanks.

Most pin tumbler locks are built on the same principles. The main parts of the lock are the cylinder and the latch. The cylinder is built from two main parts ? the cylinder housing and the cylinder plug. In order to understand how to rekey a lock, you must first understand how a lock works. In general you have the cylinder plug which can be seen on the outside of a lock as the keyhole area. When you insert the correct key inside the keyhole the key lifts the bottom pins up until they are perfectly aligned with the sheer line between the cylinder plug and the cylinder housing. Once they are aligned there is nothing preventing the cylinder plug from turning. Each one of these bottom pins can be of different height and therefore a common lock which typically holds five pins can have thousands of possible combinations.

The bottom pins are shaped in a certain way, they are small cylinders with one pointy end and one flat end, and resemble the shape of a bullet. The pointy end is the part that faces down and is in contact with the key once inserted. Above the bottom pins are top pins which unlike the bottom pins, they are flat on both ends and are normally all equal in size for each particular lock. Above the top pins you will find springs. These springs are made to place constant force on the top pins which also place force on the bottom pins. All the springs in a lock are of the same size and have the same amount of pressure. Now that we understand a bit more about the anatomy of a lock, we know that the only thing that makes a lock work with the right key is in fact the bottom pins. So in order to rekey or match a new key to a lock, all that is needed to do is replace the bottom pins only.

In order to replace the bottom pins you must first release any screws or clips holding the cylinder plug to the cylinder housing. Then you must insert the correct key and turn the cylinder plug to an angle where the bottom pins are no longer in contact with the top pins. Then you must use a locksmith tool known as a cylinder follower. This tool is usually a brass tube and is made to push the plug outward while at the same time holding all the top pins and springs in place. You would need to slide the follower from the back end of the cylinder against the cylinder plug until the plug is completely out of the cylinder and the follower has taken its place. Now you must match a new key to the plug. For this stage you would need a pinning kit.

A pinning kit would be a kit which includes all the variation of bottom and top pins required to rekey most locks. These pinning kits normally have all the codes referring to the different sized pins for different brand locks. For instance a number 2 bottom pin on a Kwikset lock would be 0.195 .Some keys have a numeric code engraved on them which represents the pins that need to be placed in the lock for it to match the key. If you do not have a numeric code on the new key you can insert the key in the plug and load one pin at a time until you find pins that are aligning with the surface of the key plug. Once you have all the correct bottom pins you need to insert the cylinder plug back into the cylinder housing the same way it was pulled out earlier. Once back in, you need to attach the screw or clip that holds the plug to the housing. Test your new lock with the new key and see that it turns smoothly. If you didn?t match the correct pins, the key might be a bit stiff to turn or will not turn at all!

Quality of Service is the most important thing when it comes to locksmiths and security. f you are going to get it done, do it the right way professionally. If you get the job done the wrong way, the family that lives in that home is in jeopardy. The family is not only in danger of burglaries, but by the person who installed the locks if they are not licensed. They can sell copies of the key to burglars. You cannot be too cautious when it comes to safety. When a job is well done you should not be able to tell that anything was repaired. That is the difference between a professional locksmith and your convenient handy man in the neighborhood.

There are a number of vocational and trade schools that offer classes on certification for various crafts and expertise. The schools offer classes for individuals to become plumbers, electricians, mechanics, or even locksmiths. The aforementioned locksmith industry is a growing trend for young adults. There are plenty of scenarios to seek the help of a locksmith:

keys get lost, tenants move without returning their keys causing a lock change, anyone who has served in the house has left for good without giving the keys, anyone who has stayed in the house as paying guest leaves without handing over the keys, or if a person accidentally locks themselves outside with the keys inside the house or the car.

If ever you are placed in one of these unforeseen unfortunate situations, it is important to not dial the first number listed in your local directory. Depending on the size of your location and city, you should first ask for references for a trustworthy locksmith company. In doing so you should specify the targeted work whether it is a car lock, door lock, lockout, etc. Another hint for the type of service you may be requesting is the length of time that it takes for a locksmith to arrive. It is very important that the company that you chose for the job only employs certified locksmiths, as well.
