What does all this mean?
- Effectiveness - Does the product do what you expect it to do?
- Reliability - Will your car always start with the device installed and will there be no false alarms?
- Ease of Use - If it is hard or confusing, people won't use it. Is the system simple to use?
- Prevents Auto Theft - Does the device actually PREVENT auto theft?

Known in the industry as "nuisance alarms." Outlawed in some major cities, including New York City. They are totally ineffective in deterring auto theft.
According to the non-profit Highway Loss Data Institute, cars with alarms "show no overall reduction in theft losses" compared to cars without alarms.
Thunderstorms, passing vehicles, slight bumps, and even temperature fluctuations can set them off. Who hasn't heard and ignored an alarm?
To make matters worse, a "code grabber" or "scanner" that will overcome any alarm system manufactured today can be purchased for less than $100 on the Internet. Even the systems that claim to have Anti-Scan or Code Grabbing Technology can still be defeated, as demonstrated on CBS' The Early Show and 48 Hours.
Some tow truck companies and car washes have and use these scanners when someone's keys are accidentally locked in a car that is equipped with an alarm. Another negative: If the remote transmitter battery dies, you cannot get the vehicle started until you replace the battery in the transmitter. Trying to find a suitable battery can be a chore in itself.
Car dealers usually will push an alarm system because it makes them more money and they are very easy to install.
The remote control "keyless entry" capability for locking and unlocking the doors of a vehicle with this type of alarm system is a great option to have, but as far as security is concerned, the remote control alarm system only interrupts the starter wire, and this can easily be bypassed by a thief under the dash in a matter of seconds.

Although they sound good on paper, these costly systems are not very effective.
They come into play only after the vehicle has been stolen, as reported by the Boston Police Department, the city in which the idea originated.
By the time the victim reports their vehicle stolen, (which is usually the next day) it has already been stripped and dumped.
If the owner of the stolen vehicle is lucky, the thief will not have removed the tracking transponder while stripping the vehicle and the tracking system will lead the police to the abandoned shell of the vehicle.
These systems are not available in all areas, and they are not very practical in big cities. Furthermore, they are expensive ($595 and up) and some even require a monthly monitoring fee.
Many people in the security industry call the system "after the fact jack" rather than LoJack.
General Motors offers a system called the "OnStar System". These systems are easily defeated by the thief breaking the antenna off of the roof of the vehicle. No Security What So Ever!
What you might not know about tracking systems and vehicle recovery:
- Vehicle tracking systems are costly, often with a monthly monitoring fee on top of an up front purchase price.
- Will your car get top police priority by the oilice after being reported?
- Most recovered vehicles have already been picked over by the thieves. Using simple hand tools it only takes minutes to get the most valuable parts of your car.
- The resale value of a recovered car can drop dramatically, and the theft will appear on the vehicle history report.
- Consider the amount of time you'll need to take off work, or from your personal life in dealing with a car theft.
As indicated by the NICB "Look for a well-designed layer 3 device - such as the Ravelco Anti-Theft Device."
A good layer three device will foil amateurs and professional thieves and should eliminate the need for a tracking device.

GM's PASSlock II, FORD's SecuriLock, CHRYSLER's SentryKey and TOYOTA's Engine Immobilizer
These transponder based anti theft systems consist of a miniature transponder which is imbedded in the ignition key head itself. When the key is inserted into the ignition a radio frequency (RF) is transmitted to the key. This in turn energizes the transponder which replies with an ID number.
If the ID is recognized by the on board computer the ignition and starting system is enabled. If access is attempted without the correct code, critical systems (ignition, starter) remain inoperable. These systems are factory installed, on almost all the new GM, FORD, CHRYSLER and TOYOTA vehicles, at no charge.
These systems keep honest people honest and are very easy to bypass. All a thief has to do is cut the black wire in the three wire ribbon cable located under the dash and measure the resistance between the black wire and the yellow starter wire with a volt meter. They then touch the two wires with the matching resistor and the vehicle will start.
This sounds complicated, but only takes about 20 seconds to defeat . . . which is probably why the factory installs these systems free. These systems are not very effective and they are bypassed all the time.
Recently, a national automotive magazine published information on how to bypass these systems, also there is are companies who manufacture products that bypass the transponder key system in any vehicle made. Available on the internet for under $100.
