I'm keen to get the chirp when locking/unlocking my car. I find myself pressing the button about 3 times, "Just to make sure.." A chirp would give an audible confirmation, and put my mind at rest. There is instructions online for 08 Legacy, Impreza, Forester(?) to enable/disable the noise via a sequence involving the key in the ignition and holding the lock button on the door. No luck.
It seems like this was standard on practically every USDM model Subaru... Seems like the ADM missed out.
The OEM buzzer sits just behind their grill, on the vertical support bar. We have the mounting hole, just no buzzer. I hoped I'd find the wires in the vicinity anyway but no luck. I also found an old page where an Aussie guy had added a piezo buzzer to the solenoid in his Outback's tailgate. I'm sure that on a sedan this would make a noise only when opening the boot, and not when locking/unlocking the main doors. Also found another site where Mini owners were adding it to the fuel cap solenoid… Either way, it just gives one loud tone for lock, and one quieter tone for unlock.
Then theres this, which I'm keen on as it would appear to be factory.. DIY chirp with indicator flash.
Instructions here...http://www.crossfireforum.org/forum/tsbs-how-articles/23009-do-you-want-keyless-entry-alert-tone.html
"...The short version is that you install a 12VDC low current ‘tone’ buzzer across the coil of the Remote Keyless Entry Relay. This is the relay that blinks the front & rear signal lights 1 time when the doors are unlocked and 3 times when locked by the remote…"
So, finally- my question is this: Do we have such a relay? And if so, is this possible? I have the buzzer sitting in the garage, just haven't had the knowledge to go at it..
