Remotes

Most seat alhambra key programming 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

As car immobilisers became more popular in the late nineties, car theft rates began to drop, however thieves are smart and constantly trying to find ways to get around security systems. They were able get through the early immobiliser systems employing a scanner to locate the transponder's code chip, and then copying it onto an unlocked key seat, but since then, technology has improved and they've been forced to come up with new ways to get around them.

Luckily, the majority of immobilisers we offer and install are Thatcham Cat 2 certified. The Thatcham Research organisation has tested and certified them. This non-profit organization is responsible for the system of grading and approval of automotive aftermarket security and alarm systems, including car immobilisers.

When the Thatcham approved system is activated, it will send a signal coded to the Engine Management System (EMS) of the vehicle which prevents the engine from starting if it does not have the proper key. This means that if the vehicle has been "hot wired" following entry, the engine will cease to function within 30 seconds, rendering it impossible to start.

Like any computer, the immobiliser may be prone to problems. Sometimes, the battery or key fob may need to be replaced. The best option is always to hire a professional to carry out the work as it will ensure that everything is fitted correctly and that it works.

Transponders

Transponders send an identifying signal back when it is probed. This helps to maintain a clear line between aircrafts and also identifies an aircraft to air traffic controllers if it is using an active radar system. The identifying information sent back by the transponder varies depending on the type of system that is used.

Transponders are also found in satellites and spacecraft to communicate with Earth systems such as cell phone networks or other networks for communication. These devices receive signals on a range of frequencies, and then retransmit them at another frequency, similar to the way repeaters function in land-based cellular phone networks.

The most sophisticated passive transponders are typically found on board aircraft. They are used to monitor flight status and provide navigation information including the aircraft's position speed, altitude, speed and the route. Air traffic controllers utilize the data from these transponders in order to control the flight path and ensure security.

A lot of personal keys have transponder chips, in addition to aircraft transponders. These chips do not require batteries and are passive. This allows the ECU to read the signal of the transponder once it is put into the ignition lock.

Most aircrafts have a switch on the flight deck that enables pilots to turn on and off their transponders. They can also select an "ident" mode that allows the transponder to broadcast its unique squawk code and help it stand out on a busy air traffic control screens.
