306 Key Fob Batteries Dying

My wife has a 1999 306 1.9td saloon which has the IR type key and is not
fitted with an alarm.

She has three keys and they eat batteries like there is no tomorrow. One
flattens its two batteries in just over a week and the other two cant last
as long as a month. It works fine the old fashioned way of putting the key
in the lock and turning it but it is infuriating that it won't work (at
least for very long) in the way that is intended and really puzzling that
all three keys have the same problem. Any thoughts please?

 

All I can say is that all is not right!

We've had our 1998 306 1.4l from 2001 and the batteries in my remote
(IR, no deadlock, single button) haven't needed changing yet. Okay, I
don't drive the car on a daily basis, but even so I might use the remote
once a day - more on some days.

Common problem on the IR Pug remotes, I've had 3 remotes do the same to
me. Had to buy a new remote.

I'm guessing the chip shouldn't draw any current with both buttons
un-pressed, a logical place to test would be the switches on the buttons
which may not be switching off completely.
(an Ohmeter across the switch should show zero pressed and infinity
un-pressed, you'll see a reading if the switch is leaking)
This used to be a common one on early tranny radios.

Oh P.S.
The most common cause of this kind of thing in tv/vid remote controls is
dried up coffe/beer/etc spilled on em.
Strangely no one is ever responsible for this, claims are usually that it
can't possibly be true, but a good clean out of the gunk with Isopropyl
alcohol always does the trick.

Thanks for the responses. It certainly appears to be a common(ish) problem.
I have persuaded my wife that IR is not really essential.
