Recently got the low fob battery beeps when unlocking my '03 1.8 3 door so I fitted a new battery but still got the beeps. Thinking that I might have bought a dud battery I got another but the beeps are still there. Has anybody got any ideas or do I take it that my fob is knackered?

Managed to fix it, cleaned the battery contacts with contact cleaner.
Should have thought of that before!
