Key problems

Recommended Posts

My  2003 forester has been playing up for the last 12 months, If the temperature of the key fob gets chilled you have to warm it in your hand for a couple of minutes before it will lock / unlock and let you start the car despite fitting brand new batteries several times. 

then today it would not lock or unlock at all, 

after dismantling both sets of keys I removed the tiny circuit board and found it full of sticky gunge and the button switch stuck down. so , out with some meths and washed it off and managed to release the switch, dried it all off and reassemble the keys, new batteries again, I did however , manage to set the alarm off. so disconnected the car Battery , left it for half an hour. put in the 4 digit code *^^^^# still nothing. what am I doing wrong ? I am booked on a cross channel ferry to France on Wednesday so getting desperate.

HELP PLEASE

the sparky  came out ,checked all the fuses  , all ok. ..shorted the car Battery out and pressed the key button. and it stopped the alarm. and now the keypad does not respond to any input at all .the armed light has gone from flashing to solid on. he thinks the problem is in the module itself. so tomorrow I have to hire a car to get us to France.

Put key in ignition turn twice so icons light up engine, oil, batt, etc then press unlock key on fob see if light flashes once if it does it should allow you to start the car. I would try everything twice I could before bypassing alarm or immobilizer not (shorting Battery terminals) immobiliser/alarm is there for a reason.

An update on the alarm problem : Had to cancel the trip to France until the car is sorted,  so I phoned a different dealership at Abergavenny, talked to the  guy in the parts department, told him all the symptoms, he confirmed that it is the main alarm unit burned out. 

Also told me that the original units have a component that cannot be obtained anymore but they have a new replacement for the whole thing , a plugin unit that comes as a  kit with new keys  for £238;50p  so I will get that this week. 

apparently this is a very common problem now. He also told me that replacement keys are only £35 each . not the £350 quoted by Shuckers of Shrewsbury. 

 Forget that by-pass unit from Stoke , they no longer make them.

Hope this helps any other member for the future with similar problems.

Thanks to everyone for your help guys.

regards Doug ( Tizaala.)

PS for anyone looking for their unit , it is either behind the glovebox , or above the clutch pedal

I can bypass faulty alarms or remove leaving just the default transponder immobilizer, for £100 to £200.

I wouldn't say the main modules are that common for faults but hand fobs are as get thrown around, wet etc.

Highly likely just fobs have issue over main module & I suspect disconnecting power if still armed made further alarm confusion.

I've dealt with more sigma alarms on subarus than I can remember & normally reprogramming key fob, new key fobs or batteries & setting new 4 digit pin codes is all that needed

Only ever replaced couple of main modules & lately rechargeable PP3 Battery in siren housings

Hope module route works out for you.

Biggest issue as getting old is Battery cell in the siren housing.

User manual in above link is quite useful, hopefully you get alarm working normally & you can rebook your ferry trip soon.

The saga continues, 

Having ordered the replacement kit last Friday ( a week ago today) the dealership had it in stores on Saturday,but instead of dispatching it on Monday  it got delayed because someone had a day off ....so the couriers Hermese , ( useless twats ) collected the package on Tuesday, 

Now common sense dictates that I should have got this on Wednesday/ Thursday at the latest , no show by mid afternoon so I rang the MD of the franchise and complained bitterly. the guy from the parts dept then rang me this morning to say that he had ordered another kit and was delivering it in person, and sure enough this afternoon he turned up with it . Much better customer service.

Should the courier ever show up I won't sign and will make them return the parcel.

what a perlaver
