Keyless entry remote control problem

[dr. d]

Hi mga Sir, saan ko po ba pwede paayos yung isang remote nung alarm/ keyless entry ko.

Nung una pumapalya lang sya, sinusumpong, until hindi na talaga sya gumana. akala namin battery ang problema.

Nagpunta kami sa concorde kung san sya binili, binuksan nung tagaduon tapos napagana nya, hindi naman pala battery ang deperensya.pero ilang gamit lang ganun nanaman...

Ano po kaya problema??

in my experience...
the battery isn't terribly expensive.
just replace it, po.
and clean the contacts in the process.

i equate "dirty contact" to weak batteries. (how can the contact get dirty in there?)
