[s-cars] IR keyless

[JR]

My IR keyless entry system in my 93 URS4 seems to be flaky.  It's hit or 
miss at best.  Sometimes I have to press it 4 or 5 times to get the door 
to lock or unlock on the drivers side.  The passenger side seems to work 
much more often, but still sometimes I have to use the key.  I've 
changed the batteries so it isn't that.  When I cup my hands around it 
and look at the emitter I see a red flash so it appears to be doing 
something.  It just doesn't work all the time.  Anyone know what could 
be wrong with it?

Thanks,

JR
