Hi all,

I've just bought a 2006 UK spec Impreza WRX (and am in love with it!). I've got a couple of issues I'm trying to get my head around regarding the alarm/immobiliser/extra keys. I tried to search but if anything that confused me further.

Essentially the car has come with single button 1 key, and very little else aside from a log book and a bit of service history/invoices for some mechanical bits (no handbook, no codes etc). I'd originally thought getting a spare key would be fairly straightforward until I did a little research.
I'm trying to work out what I need to do in order to get a second key (fully functional with button), and will I need the PIN for the keypad for it to be programmed? If not, why do I even have this keypad? I'm scared to touch it in case I end up immobilising the car or something.

Any help would be great, I'm new the the Impreza scene, or in fact any kind of interesting car scene (I also have a 2016 Mercedes A Class diesel, very dull!)

Dealer for my spare key £276

 

When new the car would have been supplied with 2 single button keys.
This single button not only opens/locks your doors (Keyless Entry System) it also operates the Sigma M30 Cat1 alarm system that UK cars are fitted with.
This means you have two imobiliser circuits - 1 that functions via a transponder in the key to the ecu/security module and 2 - fitted as part of the Sigma alarm.
The alarm keypad is for use when the key fob either runs out of battery or dies some other way and you can't stop the alarm going off.
For this reason it's very handy to know the PIN or whilst you have a working key re-program the PIN to something you can remember.

Your vehicle should also have been supplied with a copy of the alarm users manual.

As to obtaining an additional key it can be very expensive to get one from Subaru (£300 plus)
It's also possible to get a key from Timpsons or similar who can clone the transponder chip from the original giving you access to the car but not the alarm.
By obtaining an alarm fob and programming it to the alarm you are then covered.

Ouch! But I guess it might save money down the line if I find myself locked out.

That's really awesome information, thank you so much!
Can I just confirm that my working key is enough for me to re-program the PIN?
If I somehow make a mistake when I'm doing the PIN re-program is it possible for me so immobilise the car to the point where my remaining key won't work? I'm very nervous about this

 

Apologies, I did reply yesterday but the post appears to not be here!

Ouch, that's a lot, but I suppose if I lost my key it would be money well spent to have a spare

That's brilliant information, thanks. I'm really anxious about trying to change the PIN on the alarm, if I have a working key is it possible for me to somehow render that useless setting the PIN? I really don't want my new car to be immobilised!

 

Thanks both, I've actually already replied twice but it said something about the post being moderated, so here goes again!

I've tried resetting the PIN now, I had a load of beeps come from it during the process, not sure if it's a good thing. I need to work out how to test the new PIN works now (ideally without annoying the neighbours and setting the alarm off!)

Decided to ignore the neighbours complaints and set the alarm off getting in, put new PIN in and it worked, thank you so much!

I've also just ordered a handbook on eBay, hopefully save some of my silly questions!

I posted a link where you can download a copy for free

I printed that already and have written my new code on the front for future reference
I mean a handbook for the car itself (I didn't get one with the car) - £25 on eBay, not too bad I guess

 

Ahh OK

Hopefully the UK/European version not the US/Canadian one

 

I hope UK/European (I can't imagine many US/Canadian cars here in UK), but if not I guess I'll just relist it and keep an eye out for another one
