My remote control seems to be not working, i think its the buttons as ive replaced the battery.

Should i hit it with some contact spray or get a new one?

you can try the spray but i think a new one is in order

I fixed mine using this how to:

Did you just replace the battery and now it does not work? If so you will need to reprogram it. How to program it is in the handbook.

Thanks guys, resoldered the button and gave one of the sticky buttons a good spray of contact cleaner. All good now.
