well it might not have an alarm if a euro import, or it may have an alarm that relies on the immobiliser chip in the key hence why it may start.
I would try these tests:
1) lock car with remote - wait 1 minute then open the car with the key. Alarm should sound.
2) open boot and leave open-lock car with remote-alarm should beep that boot is open.
3) open flap on right hand side of steering column on binacle - is there a keypad in there? or can you just see the fuses? If keypad then you have standard fit alarm - if fuses then you havent got standard fit alarm.

The other options are that you have an alarm that isnt working for some reason or you just havent got an alarm.

If it is a UK bugeye then it should have a Sigma M30 alarm with the keypad as described.

iv looked for the fuse box and there isent one there in the drivers area under the dash there is a obd socket in the middle under the steeering wheel
on the right there is a compartment for putting stuff in like a handy ash tray but bigger .

where will i find the fuse box ............. just in case the key pad is somewhere else .

The compartment thing pulls out (lift up and pull) and the fusebox is behind. The keypad would be in the compartment thing.
Result is you have no alarm.

All official UK Imprezas from 99MY onward, were fitted with the Sigma M30 Cat 1 as standard. If there is no system fitted, as it would appear, then the car cannot have passed through the official distribution centre and must be an import.
Other points to check for a UK car:
- Alarm LED is located to the left of the clock in the centre binacle.
- Ultrasonic sensors are mounted on both A-pillars (these are colour coded and spherical on 2001MY and later vehicles)
- A "single button" ignition key - to lock/unlock the car, unless it is a very early 2001 model, see text below (An import will always have a "two button" ignition key).
- Later 2001 RHD models also have the factory pre-wired harness for the Sigma M30.

With regard to fitting an Cat 1 alarm/immobiliser to your vehicle, if it is an import, there are two main points to ensure:

1. Immobilisation
There are a number of Thatcham 2 to 1 upgrade alarm systems on the market that are designed to be fitted to vehicles with an existing Category 2 immobiliser, but their Thatcham approval is granted only on the understanding that they are fitted to vehicles whose existing immobilization system carries Thatcham Category 2 approval.
Unfortunately, the standard Subaru transponder immobiliser has not been tested on its own by Thatcham and so does not carry Category 2 approval.
Any Thatcham 2 to 1 upgrade alarm system fitted to an imported Subaru that utilizes the existing Subaru transponder immobiliser will no longer be Thatcham category 1 approved.
A full Category 1 Alarm immobiliser with 2-circuit passive arming immobiliser must be fitted to imported vehicles NOT Category 2 to 1 upgrade systems.
It is easy to check that the immobiliser has been fitted, as the engine should not start with the alarm system alarmed/sounding

2. Method of switching the alarm system
The original "2 button" ignition key on non-UK vehicles is designed solely for convenience to lock/unlock the doors, with little thought to security. It does not utilize the necessary random encryption transmission required by Thatcham to switch a Category 1 alarm system.

There are Thatcham approved alarm systems on the market that are designed to be switched from a vehicle’s original equipment transmitter, but their Thatcham approval is granted only on the understanding that they are fitted to vehicles whose existing transmitters have secure encryption to Thatcham's specification.
However, as most manufacturers (Subaru included) now use transponder technology to switch their standard immobiliser systems, there is no need for them to produce an encrypted transmitter just to operate the vehicles locking - there are no requirements in this area.
Therefore, any Cat 1 alarm system fitted to an imported Subaru that switches from the original "2 button" ignition key will no longer be Thatcham approved as the transmission is susceptible to code scanning and grabbing.

On early 2001 vehicles when the "2 button" ignition key was first introduced from the factory, a separate separate Sigma Radio Key with the Blue Subaru decal was supplied with UK vehicles to securely switch the alarm system and meet Thatcham approval.
The batteries were deliberately removed from these early "2 button" ignition keys to prevent them from working - if the vehicle were locked with the separate Radio Key and then unlocked with the "2 button" ignition key the vehicle would unlock, but with the alarm still armed, leading to a trigger when the door was opened and then confusion over which button to press!

For later UK vehicles the Sigma Radio Keys transmitter was redesigned to fit inside the Subaru ignition key housing, whilst retaining the Thatcham encryption.
As the Sigma transmitter utilizes a single button to both lock/unlock the vehicle, a new top section for the ignition key was manufactured in the UK for the single button.
If you have an early UK car (with a "disabled" 2-button ignition key and the separate Sigma Radio Key with the Blue Subaru decal) or an import with a Sigma M30, then the re-designed Sigma transmitter and single button key housing can be purchased from Subaru and programmed to your system.
The part number is SACC 3507 for these parts and should cost around £40.
Don’t pay over the odds for programming, as this can be done yourself using the keypad in a couple of minutes, provided you have the system's PIN code or an existing working Radio Key.


If the convenience of a single transmitter is important to you and your vehicle has the factory pre-wiring for the Sigma M30, then it would be straightforward to fit a Sigma M30 and then purchase the parts to build the transmitter into the ignition key from a Subaru dealer.
Unfortunately the M30 was superceded in the after-market by the S-Series some years ago and may be hard to find now.

The later Sigma S30 is widely available, and being the latest system has additional outputs and features such as Key Theft Protection etc. This sytsem will become standard fit to the next generation Subaru models from 2008MY and, although not currently available from a Subaru dealer, similar transmitter parts to the SACC 3507 will be available from summer 2007 to enable the transmitter to be integrated into the ignition key (the transmitter PCB is different for the S30 system as it uses different encryption, although the key housing shape will remain the same for 2008MY UK vehicles). Provided that you can make do with a separate Radio key for 6 months or so, then this may be the best option.

In short, if you have an imported vehicle:

1. Ensure you have a full Category 1 alarm system fitted with two circuit passive arming immobilisation fitted - NOT a 2 to 1 upgrade.

2. Ensure your system is armed/disarmed by a separate Radio Key (only the Sigma M30 can be armed/disarmed from the built-in "single button" UK ignition key) – NOT from the original “2 button” type

I hope that may have explained things, rather than confuse you further!
