I'm having an issue with the keyless entry system not working two days after I collected my STI 330s 2009 hatchback, it just stopped working and I have to press the unlock on the fob,. The interior light comes on when I approach the car and the boot works on the entry system but not the doors.
I have changed the battery in the fob for new but still no joy
I have also noticed a keypad under the flap on the right side under the mirror controls like an immobiliser type keypad and haven't a clue what it's for I have trawled the web on the keyless entry system and on here but can't find a solution to the problem and it says in the manual that the doors should lock automatically after 30 seconds if I forgot to lock it and that's not working also,. any ideas would be appreciated[/B]

 

I have a keypad same as you on my 2011 wrx sti . The keypad is for the immobiliser if the battery goes flat in the key, I have keyless start.
You should have a PIN number, think its a 4 digit.

 

I take it you've change the battery in the fob.


does it not work with both fobs?

have you tried it at various location too?

 

Neither fob works and tried at various locations, phoned Subaru and they said the keys will need reprogramming?

 

Wow keyless entry! How these cars have moved on didn't know they had it

 

Keyless entry is now working yippee!!!! I dug out the Alarm system operating instructions and reset everything and reprogrammed everything from scratch.
All the features are switched off at installation and it says in the manual "can be switched on by your Subaru dealer" so I did a bit of googling and a bit of reading and playing about with the keypad thingy and hey presto it's started working again.

 

Technically any car with a remote fob is keyless entry.

However, the 330S is totally keyless.
