Default Key immobiliser

Hi I have an late 02 early 03 Outback with I think the same alarm/immobiliser system as on that aged Imprezas

Thing is I am down to one key.

This key has a single button built into the key, that arms and disarms the car alarm/ operates central locking.

More importantly you need to push this button after turning the key in the ignition to de-activate the immobilser to allow the car to start

A new key costs more than the car believe it or not. I was wondering if I go another key off ebay for £30 or so could I program this key to the car? It seems that on some US Subaru systems if you turn the ignition from lock to the first click and back again 10x the hooter sounds and the key is programmed to the car. Is this the case with UK versions with just one button ?

If this is the case, does it also program the immobiliser function to the car? If so then all I need to do is get my existing key blade copied and then somehow fit this blade to the newly programmed keyfob

Anyone know anything ?

You can program the lock & unlock function pretty easily as long as you have one working remote or the pin number.

the immobilizer is a different kettle of fish, if you can get the chip out & swap it then it should work fine, if not then its a trip to the dealers to reprogram the ecu to the keys

thanks for this, I have no code, just 1x 100% working keyfob.

I would like another keyfob. If I was to buy a s/h key of the same single button type I could program this to operate the central locking, but not the immobilser?

As it is an old knock about farm car, I was thinking of getting another key cut(blade), then bodging this onto a s/h keyfob with a single button on it. I would then have to take this to Subaru for it to be programmed to the immobiliser ?

As the car does not go on the road this is going to be a problem and when Subaru dealer sees the bodged key, I doubt they will want to programme it. If they do they would charge and arm and a leg I bet ?

I found this from elsewhere, a post on its own, I wonder if there is any truth in this and is it on about programming the immobiliser ?




I reprogrammed mine its really very simple...

The 'Reprogramming' was simply a matter of connecting a white connector found in the left hand side front door pillar and pushing one of the buttons on the key to get it register with the car.

Its really very simple, I don't know why it took me so long to figure it out! There is a white connector behind a trim panel on the passenger side door post in the foot well (left hand side of the car on RHD and LDH cars). When you open the panel the connector should not be connected, connect it, then close the doors of the car and press the open button once (I did this sitting in the drivers seat LHD). This should make the door locks click, and thats it... your key is programmed (don't forget to undo the connector afterwards).

Of course the key bit probably wont fit the locks, i use my non remote spare now and cut the key part off with a grinder and now have a smaller, lighter remote fob.

I got my second key fob off ebay by the way, cost me the grand sum of 1£!

But then you may be talking about separate fobs... I just reread the post!

Paul,

Have a look at this thread: https://www.scoobynet.com/scoobynet-...-pad-code.html

This page also describes how to add more fobs: http://www.scoobypedia.co.uk/index.p...RemoteControls


I didn't know my code either, but had one working fob, so I changed the code using the method in the first link, and then bought another fob off ebay and married that one up too.

I believe the method works for newer sigma alarms too (i.e. the ones where everything is built into the key, rather than a separate fob), so you should be good.

Much appreciated Henrik.. The links seem very informative, however I think it relates only programming alarm to keys ?. So I take it, programming the immobiliser to the key chip to be a very different thing?

Part of me says yes as I have been told the immobilser chip is separate to the alarm circuit (key just needs to be very close to ignition) However that said, why do I have to turn key on, then push the single button on the key to get the car to start if the two circuits are not related ? Unless of course the single button press just energises that immobilser chip temporarily so the car can read it ?

Shame the immobilser can be disconnected as it is a farm car and one in a condition that is dumped not nicked !

Subaru want £250 for a new key up and running btw

The alarm fob will disable the immobiliser too.

Yes, but that doesnt mean that the car would recognize a different key even with the inbuilt alarm fob programmed to the alarm though

My understanding is that the alarm and the immobiliser are different entities here. They are not related. Ie a new key, requires a blade to be cut, key mated to the alarm/central locking and thirdly the immobilser has to be programmed to recognise the chip in the key, before you can start the engine.

This last requirement is the awkward one to get around

The key will need to be coded to the ecu, a dealer can do that or a mapper using Ecutek software can also code keys, I do it on a regular basis to accommodate ecu changes takes less than 5 mins to do. You need to get both keys coded together

So if a mapper is replacing the ecu and going ecutek at the same time. Can my existing keys be coded?

What would happen if I had a key which wasn't coded to the car. Can the mapper code in the new key or would the new key need to be coded into the old ecu before it can be changed to the new one?

Regards.
