Remotes

Most seat key fob drivers keep a spare remote in the house or garage, but when they lose it getting replacement keys from a dealer is expensive and time consuming. This is because most dealers will programme the key using the car's computer which will need to be reset. However, many people buy second-hand keys off the internet that are not programmed to their car. This can be a much cheaper alternative to going to the dealer. But, these key will not start the car because they will not have a transponder chip inside them. You can see the chip (yellow) in this picture below, it is a Dual Inline Package or DIP 18 pin chip. There are also a diode, transistor and resonator, all these parts make up the key's circuit.

Immobilisers

The number of car thefts started to decline since car immobilisers became more popular in the latter part of the 1990s. However criminals are always looking for ways to evade security systems. The initial immobilisers were bypassed by scanning the chip's coding and then copying it onto a blank key. However, technology has advanced and thieves have had to devise new tricks.

Luckily, the majority of immobilisers we offer and install are Thatcham Cat 2 certified. This means that they have been tested and approved by the Thatcham Research organisation. This non-profit organisation is the grading and approval system for automotive aftermarket alarm and security devices, such as car immobilisers.

When the Thatcham approved immobiliser device is activated it will send a coded message to the Engine Management System of the vehicle, which prevents the engine from running until the correct key is available. This means that if a car is "hot wired" after entry and the engine is cease to function within 30 seconds, rendering it impossible to start.

As with an electronic device, the immobiliser could develop problems and sometimes the battery inside or the key fob may need replacing. It is best to have an expert do the work and make sure everything is installed correctly and is working.

Transponders

A transponder is an instrument which transmits an identifying signal upon being questioned. This helps to maintain a clear line between aircrafts and also identifies an aircraft to air traffic controllers when it is using an active radar system. The information that is transmitted by the transponder can differ based on the type of system that is used.

Transponders can also be found on spacecrafts and satellites, allowing them to communicate with Earth systems like cell phone networks or other networks for communication. These devices receive incoming signals in a variety frequencies, and then transmit them at an additional frequency, similar to how repeaters operate in terrestrial cellular phone networks.

Often, sophisticated passive transponders can be located on aircraft. They are utilized to monitor the status of the flight and provide navigation information like the aircraft's location as well as speed, altitude and route. Air traffic controllers utilize the information from these transponders to manage the flight path and ensure security.

A lot of personal keys have a transponder chip in addition to aircraft transponders. These chips don't require batteries and are purely passive. This allows the ECU to read the transponder's signal whenever it is placed in the ignition lock.

The flight deck of the majority of aircrafts has a switch that pilots can switch their transponders on or off. They can also choose an "ident" mode, which enables the transponder to broadcast its unique squawk code and help it stand out on a busy air traffic control screen.
