Just bought my 2nd Subaru Outback.Had a '05 plater, sold it for a Volvo V 70 - big mistake, only kept it 5 months! found my '12 plater, very pleased with it EXCEPT FOR- intermittent problem with remote locking/ unlocking on the key fobs. Replaced batteries in both, (both low, 2.8v in one! 0.6 in the other. No different, still having probs. Tried unlocking by using key in door, get in, alarm goes off!

Any ideas, anyone?

NB. No prob with main car battery, starts 1st time every time.

Is it not unlocking sorry might have just miss read the question or is it locking on it's own :) 

You might want to try unravelling / re-positioning the antenna wire - I believe it is under the carpet on the drivers side

Thanks for getting back to me.

1. It can take four, five or more attempts to unlock, then can take three or four to lock. If I unlock it by putting the key in the door, the alarm goes off once I get in.

Tried putting the fob on the windscreen (Forester suggestion), no difference.

2. I'll have a look for the antenna wire suggestion, thanks for the tip.

Thursday. Looked under the carpet, only lead I could find was the cable feeding the electric seat adjustment.

Any ideas why the alarm goes off and the engine won't start if I get in by using the key in the door lock?

You need to use the key in conjunction with the pin pad to manually De activate the alarm,

May be of some use as they haven't changed the systems much
