Two mile commute
Senior Member
I've been using the Onguard lock every week since about May and now the lock won't undo. The keys just turn in the lock with one key almost breaking. The lock is currently in two parts as I could unlock it but cannot now turn key to pull bolts back to allow D to go into shackle (if you follow). I've tried GT85 and squirting chain oil in the lock but no joy. Any suggestions, please?
