Hi Guys,
2003 Elite
My remote locking was working fine until this evening.
On leaving the car tonight, the system wouldn't lock unless I held the key against the drivers window while operating the buttons.
Changed the key battery, still the same.
Tried to re sync but it won't operate the locks to confirm.
Tried my spare key, exactly the same problem.
Took battery out of key for 15 mins, tried to re sync but still no joy.
Thought if I disconnected main battery then the system might reset itself, but all that happened was alarm went off.
Any ideas chaps..................?
-
did you buy your spare battery at the same time as the one in the key? Maybe both are flat? More experienced chaps will be along in a bit no doubt.

Nope.....new battery, also checked its good with a multimeter, solid 3v

Yo disconnect main battery, disconnect within 15s of switching off ign to prevent alarm going off.
As to the sudden reduced range, not sure. Alarm ecu (with integral aerial) is in drivers kick panel.

Cheers for that info.....I'll disconnect the battery for half an hour to see if anything resets itself. I've got my radio code ready... ;D

You'll need to reset windows and sunroof after as well.
Not convinced it will make a difference, but let us know :y
-
You were correct........range still rubbish... :'(
It works fine inside the car, but still need to be within an inch of drivers door window for outside.
Its as if the key signal is too weak, but I can't see both my keys going wrong at the same time.
Changed batts again but still no joy.
Strange the keys still work without re syncing, but at this much reduced range...
-
Update.....
Still poor range this morning, but when I got to work it was back to normal. Returned home....poor range......went shopping.....worked fine...back home....poor range again..
So, is something close to my home suddenly interfering with my signal. If so, what could it be???
Nothing had been changed in my house.
Anyone know what frequency the keys work on?
Maybe someone in our street has bought an illegal TV repeater, or started a pirate radio station... ;D

483Mhz ain't they, one of the licence exempt bands

And my remote doorbell has stopped working too...same frequency.
Getting spooky................gonna ask neighbours if they bought any new toys over the weekend

You going to Fairford next week? 8-)

Probably way off the mark here...its when you said about your remote doorbell that made me wonder.
Would a mobile phone signal blocker cause the interference you describe (basically the do as described...kill a mobile phone signal.. :-?)...i know from another forum these have recently been sold too members who enjoy being mindless prats and blocking neighbours mobiles from working.
Just a thought. :y

Have you lost your mobile phone signal as well then? easy way to dismiss that one!! most doorbells have a range of settings / frequencies - tried another?
Although not necessarily on the same frequencies, it wouldn`t be unknown for something new to the area giving off some form of "harmonic" signal that is disrupting your stuff.
Same can be said for 2-way radios (taxi/pmr) and CCTV with the IR/Night detectors can also knock out the Infra red alarm remotes (great fun in our car park with that one!)
:(

Well, as mysteriously as it started, the problem has gone.... :-?
This morning the doorbell is working fine, and the car could be unlocked throu the kitchen window as before.
We had no trouble with our mobiles while this was happening.
I got to find out what this was...really buggin me... ;D
-
That's an odd one. Dad has trouble with the fob for his Harley under mobile masts and some cctv installations
-
The problem has returned this morning................
I remembered I had a scanner somewhere, so I've had a play with it, and found a very strong signal at 433.90/433.92 Mhz around my house and into the front garden.
If I press my key near the scanner I can hear it transmitting, same with my doorbell push.
Now realised its also blocking my lounge/dining room electric blinds.
Any ideas guys............?
-
If you have a scanner, make a loop aerial, plug it in and go hunting.
-
Ahh, a bit of fox hunting. http://en.wikipedia.org/wiki/Transmitter_hunting
As Dave said, fabricate some sort of directional antenna and see if you can find the source. It can be fun.
License exempt devices are supposed to only be capable of transmitting in small bursts so they can't jam the allocated frequency but if something has gone wrong it could be a duff device of some sort transmitting permanently I guess.
Also be aware that 433.92 is in an amateur radio band so a local amateur could be using it, although it's unlikely that they'd be doing so for long periods at a time.

In light of your blinds etc also being remote control, before chasing around, kill the power to the house and just make sure its not one of your own devices thats gone faulty
:-/
-
Any resolution to this? I am intrigued!

Having now spoken to several neighbours, all are having the same problem with key fobs (various makes of vehicles), but none have had any new transmitting equipment.
Still getting a strong signal on my scanner at 433.92 Mhz, which does a double bleep every couple of minuites.
Several of us have now emailed/written to Ofcom to see if they can help
Its a real pain......................!!
-
Shut down the power to each house one by one to determine where the rogue device is located.
Could be your doorbell gone faulty, anyone had a baby recently ? (Baby monitors play hell with my Home hub)
-
Your not near Luton airport are you?
-
I finally contacted Ofcom last Friday, had a phone call in reply to my email within 10 mins.... :o
Ofcom guy came round tonight armed with some impressive kit.....took him all of five mins to identify the problem.
Next door's Sky magic eye had gone faulty, and was transmitting a constant signal flooding the area. Embarresment for them then...she was telling me the other day how fed up she was with her BMW locking playing up, and how her TV picture had got very poor... ;D
-
A good result ;). Especially as it was someone else's fault! :y
-
A fascinating educational thread John, which one assumes could affect anyone when such a device goes wrong and now we are all fore warned! 8-) 8-)
Glad you got it all sorted in the end! :y

Great Stuff :y thought it was going to be another Xfiles episode :o
