DANGEROUS DAVY

Anyone had problems with there alarm when parked next to, police stations I had to get towed away tonight from police station second time this year, apparently radio masts interfere with remote signals for alarm, anyone had this problem if so do you have a cure for it help.

Never heard of that.
How do the police subaru's in manchester cope ?

It happened to me at an airport once, had to overide the system.
On a lighter note, are you any relation to Angry Anderson

Affected my 00MY UK car. Bugeye not bothered by them. Use the keypad to overcome the problem

Police stations , fire stations, just about any building that has a radio/microwave transmitter will mess up some Car alarm systems, i had to get mine shielded when i lived in the big smoke as i was between 2 high freq masts. I dont know what you may have to do, what make and model alarm have you?

darren...

It's the Tetra radio system - it's known for interfering with car alarms / remote systems. You'll also find that you can park in the same spot each day and it won't always affect you

It was something to do with cars between a certain date. they used a frequency that is now only used for the emergency services. As mentioned, you should know the pin to override this on the alarm keypad.

yep, sigma provided the alarm for subaru, they found problems with police stations and something els, which also effected the range, me m8 told me as he worked for sigma and changes the reciever unit in the alarm for me

I find that in most cases, if you unlock the car maunually, get in and shut the door (alarm will be going off - obviously) then try the remote whilst inside the car with teh door closed, you'll find it'll work.

its a sigma m30 alarm cars a 2000 bugeye wrx

Think I will change the receiver unit shouldnt be to expensive, or buy a P1

DANGEROUS DAVY

remote would not lock car used key to lock it when I got back to car opened it with key press key fob from inside and outside with door open and shut till I had blisters on thumb LOL

Works with the old unshielded TOADs

I was quoted about £150 from Subaru dealer to change the alarm unit to one more shielded. Order period for unit was quite some time.

So, I looked up the keypad code number and use that when required - have to practice in the dark as numbers are not in the usually calculator/keyboard layout :-)

Since owning the car from new in 2000, i have been caught out less than 10 times - but always to maximise embarrassment!

Cheers,

Ive got an 02 bugeye with a standard subaru alarm - alarm keypad - do i have on of these, if so where and how do i get the code - (subaru dealers?)

Chelspeed

Keypad is down by your right knee, pull a little flap down and the key pads inside.

The code comes with the car when new but often gets lost or ignored as, unless you get this kind of problem, you never need to use it.

powerman1

there is an upgrade available and i think it was about £36 from the main dealers. I suffered the same problems on my MY00 when it was parked near certain mobile phone masts

DANGEROUS DAVY

I have tried using key pad its ultra sensitive every time I push a button it flashes about six times and never seems to work its been checked by subaru dealer they say it works ok even tried it when key fob was working still did not work

Not certain (ut S/Net user Sigma Sam posts in security)is very knowledgable in these systems.

IIRC the early Sigma M30's (1999-2001) were susceptable.

Some 1998-2000 models wouldn't start if your mobile phone was in a hands free cradle by the Dash apparantly can interfer with the Transponder signal

Ps here's a quote

Where is SIGMA SAM when you need him?
Oh should say OE SAM now days to be PC.

From your descriptions it would seem that you do not have a faulty radio key/alarm but the security system is being affected by "Radio key lockout" - An explanation of which is below:

Right here goes....
All alarm systems manufactured for use in the UK in 1999 were required to operate on the frequency of 433MHz. Subsequently, in late 2000, the government allowed the introduction of "Tetra" radio networks for telecommunication companies, the military, emergency services etc which was allocated the 420-430 bandwidths.
Although not exactly the same frequency these "Tetra" transmitters are licensed and are allowed to operate at around 20,000 watts, compared with the alarm systems 0.5 watt radio key.
As a result when you are near a transmitting "Tetra" mast you can get a degree of bleedover as their signal is so much stronger and this can swap the transmission from the radio key.
The problem is not exclusive to this system and can occur on a number of manufacturers systems produced prior to 2001, due to the same outside influance.

In 2001 the reciever boards were re-designed to focus more accurately on the 433.92MHz frequency as soon as the problem became evident, however the systems manufactured prior to this were not considered faulty and therefore were not considered for warranty. However, as a goodwill measure, customers who suffered exceptional radio lock out were offered an upgraded reciever board if the vehicle was still within the warranty period. This measure finished in December 2004.

The keypad, supplied with the security system as standard, is intended to overcome instances such as occassional lock out using the 4 didgit pin code, if this is not available please pm me, and I will take the case from there.

In essence to overcome this, when you are affected by radio key lockout either use the four digit pin through the keypad as this is not atall affected by radio lockout or obtain a later shielded receiver ECU from Subaru they will supply and fit this ECU and the part no for the ECU just in-case you decide to follow this route is SACC3465, either way your problems should then be solved.

Hope I havent bored you too much with this info, but it is for everybodies benefit in the long-run.
