My lock was rusty and key snapped while trying to unlock bike so now its permanently locked I was trying to open the lock to use the bike, the key was jammed and I forced it so much it snapped so now part of the key is inside the lock and consequently the bike is locked and the whole lock is impossible to remove. What is the best procedure to follow?
If this is the cable or chain lock use bolt cutter. If it's a D-lock (U-lock) you have to use a hacksaw.
