Hi, for anyone having this problem, as below, make the hole behind the badge, drill the two anti-tamper bolts out, the lock barrel can then be removed, remove the plastic rod and then use a screwdriver to open from then on, thats what I did, also with the bits out you can see what the issue was and may be able to put it back together again.
