Key Not Unlocking Car

[dram300]

Wife called from shops this morning.

They remote key fob won't open the car up. I suggested she go get a battery and a wee screw driver from Maplins which she did. Key still won't open car. Is this just a key synch issue now or is something else wrong?

Hoping someone comes up with a clever idea whilst she shops a bit more and I try and find the PIN code for the keypad !!

Any ideas?

Mate, its probably a mast or somthing... If you know the code for the alarm, then open the door with the key, this will set the alarm off, then punch in the code in the little keypad (Either in the glove box, or the little cubby down to the right of the steeringwheel)

But dont put it in too quick, as you only have a couple of attempts and then you have to wait 30 minutes to try again!

Don't think its a mast, the car gets parked in the same place every week so ??

If only I knew the code !!! Its know its around here somewhere, I've used it in the past to immobilise the car for holidays.

Its in my best interests to explain to do it slowly ... a lot of shopping to be done during each 30 minute break !!!

Cheers.

Key still no worky, but shes in the car and about to drive off.

Hopefully figure out why soon enough - guessing its key synch post battery change !?!?

Possibly, I cant remember, but I think that if you leave the battery out for too long it can lose the code....

Might be worth taking a look at the Sigma Sam thread...

Theres lots of good info there about reprogramming keyfobs and the likes... Hope that Helps.

It could be interference from a shops alarm/security system ,i had this problem before.

[StewartyBoy]

A common one this. Subaru systems seem to be open to interference, it must run on a wideband. Get it home and see if it works then.

though one question now that she's able to move the car, is how old is it? because from later 2001 I think onwards, so newages basically, shouldn't be so badly affected because they run on the different frequency...

[dram300]

New age (2005).

The car was parked in EK shopping centre like it has done loads of times in the past.

She got it going with the key and code.

Tried her key when she got home, didn't work. Tried mine and it worked just fine. So I set about re-synching the keys with the car and hey presto, its all good again. Checked the old battery too - 3V, exactly as it should be.

For some reason, the key lost synch with the car ???

Anyway, its all good now.

Thanks for the replies.

I had exactly the same in my 2005 Sport today - no mobile and 3 mile walk each way (went togetthe spare key and/or code) wearing tshirt and jeans in -3°C! Just about warm now but both keys working fine now the cars at home! Odd.
