I'm hoping someone out their can help
When trying to get in to the car I'm standing there like a numpty pressing the button, while holding the key near the mirror
So I changed the battery thinking its that but no its still the same...... now I should say that once you start the car for a few minutes and turn it off the key works perfectly locks and unlocks go back 15 minutes later same thing stand there pressing the button
I've tryed the key pad that I know did work but now it just flashes and nothing happens
Does anyone have a answer to this

 

Bump

 

is it the M or S 30 ?
the M30 was prone to interference.

 

Its on a 04 wrx
How can you tell the difference ?

 

Will be M series and yes it was prone to interference they lost the BMW contract
because of radio lock out
Is it in one place or random places ?

Ian

 

It can be any place

 

I tryed it this morning and again nothing so I took the key apart and held the circuit board against the battery and pushed the silver button on the board and unlocked and locked several times put it all back together and it still worked
Repaired a snapped bolt and went to lock it nothing for about 5 or 6 presses then it locked and unlocked I'm hoping it's just somthing stupid because it is doing my nut in

 

do you have a spare key / fob you could try for a few days to see if the symptoms change ?

 

Yeah sort of I managed to get a genuine subaru key blank a couple of months back came with both internals for sigma m and s.... but I put it away with the intention of getting it cut and programed when I had time but now I can't find were I put the bloody thing

 

I found the key blank this morning so poped a fresh battery in and the sigma m circuit board, programed the new key and old one in and wouldn't you know it they both work perfectly even the old one now

Thanks for the help it's good to know there's places like this you can go for advice
