    RF interference

    Just wondering how common RF interference actually is and how often, if at all it has affected you

    I had this happen to me today, when parked in a shopping center car park, I was in the open and could not see any transmitters around, not near any shops etc

    Parked up, got out, pressed the fob to lock, and nothing, tried several times still no go, locked with the key, and went to find the wife.
    Got back and tried again, still nothing, opened with key and set off alarm
    Gave up after around 10 minutes and got the bus home, (much to the delight of our 4 year old, such an adventure!), to grab the EAK and nanocom, spare key etc
    I knew it was RF interference as I had not had any problems before, but was still a bit frustrated by it all
    Got back to the car park, pressed unlock and flash go the light and click go the doors

    Of course my wife thought it was hilarious, I was just glad i got it sorted

    My next coure of action would have been the EAK, (I wasn't sure if it was correct though as i have never tried it), trying to move it back a couple of spaces, and finally a call to the RAA.

    So got it home and checked out the EAK and will store it in my phone for future reference

    Ah, the joys of technology!

    Using Nanocom you can change it to whatever you like...

    My EKA is a well known to me (and wife) code now

    Cheers Mike,

    Had the EAK, but it was at home - no good to me there I know, hence the bus ride
    I have since verified that it is correct with the Nanocom, so I will be prepared next time

    I was more frustratred by the whole thing, and just wondered how common it is?

    The Telstra tower at Black Mountain ACT has warning signs about this. My rangie had to be locked and opened manually. Otherwise no problem.

    About 5 cars ago I had a Jeep Grand Cherokee and I had the same problem, park near a telstra mobile tower and no lock or unlock but worse issue with the Jeep it also inhibited engine start unless it received a signal from the key pad. Only solution I found with the Jeep was to shield the internal receiver area with an aluminium windscreen sun protector until I could get a signal to the reciever system in the car. I found at the time that the USA frequency for the car keypad clashed with Australian phone frequencies at the time. A year before I replaced the Jeep Chryler replaced the car receivers and key transmitters with ones that were compatible with Aussie standards!

    Some years ago there was a Telstra tower in a country town over here... was notorious for stopping cars from starting. It was safe enough to drive through the Twilight Zone but not to shut off the engine.

    Solution was to push them a dozen or so metres further down the hill...

    Understand that Telstra was not shy about unofficially boosting the RF output where it needed a commercial advantage... A bit like their demonstration range test when CDMA as being rolled out.

    With my D2, it got to such a point, and me very paranoid, that wherever I parked I would try and lock myself in immediately on shut down. If it didn't I'd start the engine immediately (during the time delay) and move the truck till I got clear air. Over the years the problems went away. A lot of the problematic areas contained Chemists or bank sub branches and their alarm systems.

    Cheers

    RF interferance

    Happens in the places you don`t expect,Tamworth,near tourist centre/train station for one. Something there obviously!
    Supermarket car parks..on occasion!

    Hint! place key fob under right mudguard then try.
    acts as a shield against RF interferance.

    Happened to me at the BP servo on Hume Hwy near Wallan - no response from key fob, wouldn't work with keyand I didn't (still don't) know how to use the EKA.
    Ended up getting towed home to pick up the spare key! Tow truck driver said he picks up Landies from there all the time with similar issues.

    Know your pain mate - Disco 2, 2002 V8. Amcal chemists used to upset it. Also, the procedure for manual unlock with key in driver's side door lock (turn left 6 times, then right 3 times etc etc) wouldnt work in shutting down the alarm nor disabling the ignition cut out. The only thing that worked was waiting, and at times pushing the bastard 100m away...

    I got sick of it and out of warranty I approached LR who initially fobbed (no pun intended) me off, and I told them that the late D1 frequency was much better and less prone to interference (info I got off an ex-dealer) and that this is the frequency I required to use the vehicle for what it was designed for...ie running.

    They came to the party and took down the hoodlining and replaced the receiver and both keys with the old frequency and not a drama ever since (so for about 6 years now...and that includes same places as before that would regularly cause problems).

    Cheers
