Talk:Remote keyless system

message: Is there any truth to the rumor on the internet about being able to open a remote keyless entry system with a mobile phone? See this wsdmag claim. And should the truth or falsity of this be mentioned in this article? ~ Nanobug 16:23, 10 November 2006 (UTC)
replies: text: False. A mobile phone converts radio signals to and from sound; it does not relay radio signals.  There may have been apparent successes at short range due to the ordinary range of the system being longer than the user thought, and the distance may then have been exaggerated as the rumour spread.--QuantumEngineer 16:43, 10 November 2006 (UTC)
replies: text:  False. This has also been dis-proved by experiment on National Geographic Channel's series "What Would Happen If". Is it worth adding a section on this myth in the main page? Jetsetpainter (talk) 12:22, 30 January 2008 (UTC)

message: I've never seen or even heard of a tv remote operating on radio instead of IR. I suppose that does happen in american sitcom where neighbours change your tv channel. But I think that the sentence is obscure at best.  —Preceding unsigned comment added by 212.50.147.101 (talk) 10:47, 31 January 2008 (UTC)

message: Dear Curator(s),
Firstly it's a transponder not a transducer.  The "bubble" is the car sending an uncoded signal on 125 or 134 kHz.  When the smart key gets close enough to "hear" this it responds with a coded signal on 315 (US) or 433 MHz (elsewhere).  If the car recognizes the code it does the active or passive things described.  So that's an active transponder.  The older keys that you actually had to put in the ignition (lock or slot) had passive transponders (transmitter powered by received energy).  The smart keys also contain such a passive transponder as backup if their battery fails - in these circumstances you have to enter with a mechanical key and hold the smart key near the start button.  All of this info is widely available on the web, but I am not clear on what constitutes acceptable evidence on Wikipedia.
Here is a link to a smart key test box http://www.thediagnosticbox.com/downloads/TDB003_Manual.pdf 
Please see pages 4 and 5 which describe the system including frequencies. 
Anecdotally some vehicle manufacturers changed the interrogation frequency from 125 to 134 kHZ when the former was preempted for EZPass and similar systems.

message: Does anyone have any additional sources on the history or keyless entry systems? This seems to be lacking in this article. Also, it would be useful to have some sort of availability data, e.g. what percentage of cars are equipped with RKEs (from government or manufacturer statistics possibly?)
