Re: Key fob is not switching off alarm or lockin the...
Check
your remote to see whether it is held together by a small Philips-head
screw. If so, remove it. Look at the join seam that runs along the
middle of your remote. Search for a small indentation in which your
miniature flathead screwdriver can be inserted. If not, use the seam
itself, and gently pry it apart with your flathead screwdriver.
Spray the inside of the remote with canned air to remove any
debris. Remove the battery, and dispose of it unless it is relatively
new. It should be replaced when you re-assemble the fob.
Remove the button pad from the top of the remote, and using
the alcohol with cotton swabs, clean around the buttons and the plastic
frame it fits in to make sure it's clean. Lay it aside for it to dry.
Remove the remote's interior circuit board. Generally, the
problem with remotes is that the contacts have worn thin and have ceased
to make a proper electrical contact with the rest of the remote. These
contacts are usually gold in color. Clean these with the cotton swabs
and alcohol. Reassemble your fob, and check to see whether it works.
Reopen the fob if the clean contacts did not make a
difference. To rebuild the contact surface, do one of several things:
First, use a tiny bit of metallic paint applied gingerly with a paint
brush or build up the contact surface by rubbing it with a pencil.
Another solution is to use conductive coating, which is available at
electronic shops. Let it dry 12 hours before re-assembling the fob and
checking to see if it works.
Replace your battery, and close your key fob by pressing the
two halves back together. It should click back into place. Replace any
screws removed upon disassembly.
