REMOTES AND TRANSPONDERS

How Remote Controls Work

Remote controls for alarms and keyless entry systems are coded in various ways.  All remote controls use an integrated circuit, commonly called an IC or ‘chip’.  A chip is actually a tiny electronic circuit assembled and sealed in an epoxy resin. In most cases the actual coding is visible on the printed circuit.  Some methods of coding are, however, not visible.  There are usually two rows of pins protruding from the sides and extending below the case. The pins are the chips means of communicating with other components on the printed circuit. 

The purpose of the chip is to encode a radio frequency transmission, or an infra-red beam of light, in such a way that the ‘receiver’, in the unit, will recognize the signal and, if the code is correct, act upon the instruction sent by the remote control.

Each generic type of chip is capable of producing many different codes within a given ‘style’ of codes.  Moreover, each generic type of chip is different:  One type cannot produce codes that will operate a unit using a different type of chip.

Some remote controls have two buttons. In these cases, usually, one button arms or disarms the unit and the secondary button is used for ‘panic’ or personal attack setting the alarm siren off if used in an alarm.  In other cases one button may arm the alarm and the other button disarm it. There are numerous other purposes that extra buttons can be designed for. As for the transmitted codes of two button devices, it is normal for the secondary buttons to modify the transmitted code pattern, in a minor way, allowing the alarm to recognize the main part of the code pattern as belonging to it and the minor alteration as an instruction to perform a specific function.

Code Labels

Code numbers are almost invariably printed or written on white labels, usually mounted on the encryption chip.

Code numbers are never printed directly on anything other than a label , unless hand written onto the printed circuit. Any numbers printed on the encryption chip are NOT code numbers. Every code number refers to the data pulses that will be transmitted by the remote control.

For encryption chips that are coded by solder bridges or print cutting, the code number is translated, usually by a mathematical algorithm, into a pattern which is then systematically applied to the transmitter printed circuit and thus to the encryption chip. For hard-programmed and EEPROM types the code number is, again, translated and 'written' to the micro controller or EEPROM.  Not all alarms use code numbers, especially ‘Code Learning’ types. These types do not, normally, have code labels.

Code Learning Remotes

Aka, "Self Learning" Alarms:  This type of alarm ‘learns’ its code from a suitable remote control. They cannot learn codes from remote controls designed for any other make of alarm.

This system has the advantage that code numbers are not actually necessary for the purpose of making a replacement remote control as they can usually learn 2 to 4 different codes.

The disadvantage is that if the user has lost all remote controls for the alarm, it is very difficult to supply a replacement.

The method of coding the remote control may be either Visible or Electronic. The methods of learning new codes varies from model to model, but generally it is necessary to have one working remote control to initiate the learning process. Of course, if the coding method is visible, then an exact copy can be made, of the original, thus the learning process is avoided.
