Can anyone assist, tried to get replacement keys for my Abbey Spectrum 418 and not having any luck, none of the locks have numbered identification so it’s impossible to get replacements. I’ve also tried a master key that’s supposed to open any lock, didn’t work! Any suggestions? I’ve also tried to find a locksmith that will replace all the locks for me but no caravan service suppliers in my area do it, feeling a bit lost. I’m in Cirencester, Thanks in advance 👍
