Keyless Entry Problem on 2002 Honda

Son's 2002 CRV keyless entry has developed problems . It works eratically.
He has use his other key also and it does the same thing. He has even tries
new batteries to no avail.

Is there a central receiver on these?
Any idea on how to remedy or check this out?

 

-------------------

Start by injecting all five locks with LockEase and 'massage' it in with
the key to be sure the mechanisms aren't dragging, causing too much
friction. I got the stuff at a locksmith, but I think Home Depot and
Revy carry it too. The lock on the tailgate of the CR-V tends to
accumulate crud the worst. The ignition switch is also included because
it gets a lot of usage. It's a graphite aerosol, and therefore messy,
but it's the same stuff a locksmith might use to do preventative
maintenance on your locks.

There's lots of 'articles' at hondasuv.com if you want to search around.

I get it at the local NAPA... it's fairly common and good stuff. After using
I run a key in and out a dozen times or so and wipe the key with a shop
towel (or my jeans if the wife isn't looking!) to control the messiness a
bit.
