My GM keyless entry pad is intermittant. Cleaning dosen't seem to help.
Anyone seen a schematic for these things?

Thanks, Chuck

Hi!

Have you changed the battery in any recent time?

I worked on one for a late model Chevy Malibu recently and found bad
solder on all of the battery connections. Resoldering the contacts
(some of which were easier than others) restored perfect operation.

I would not call it really easy, as the through-hole pins of the
battery holder were only barely long enough to be seen on the other
side of the hole in the circuit board.
