Key fob not working

Can anyone recomend a good place to have my spare key fob checked out and programmed in Norwich or Norfolk. When we purchased the car the vendor said it just needed a new battery and guess what ? I've given the various recommended methods a try but no success so any help would be very much appreciated

Is it a Lucas (square) or Pektron (round) fob?

The subtext to Bruce's question is one is problematic the other less so. Let's hope yours is an earlier car in which case it'll be the square Lucas fob & that is the lesser of the two evils.

Who’d of ever imagined that Lucas the Prince of Darkness, would be the preferable alternative! :omg: :bust:
